in other domains, and inappropriateness of sequential lifecycles. It explores the key ideas in
iterative lifecycle and agile development processes, and their expression in the Unified Process,
Extreme Programming, DSDM, and Scrum. It examines agile modeling and the tradeoffs of
formality and specificity in modeling, versus rapid programming. The presentation concludes
with suggestions for high-impact visual modeling techniques.

In this talk we give a tour of Natix, a database management system
designed from scratch for storing and processing XML data.
Contrary to the common belief that management of XML data is just another application for traditional databases like relational systems, we illustrate how almost every component in a database system is affected in terms of adequacy and performance.
We show how to design and optimize areas such as storage, transaction management comprising recovery and multi-user synchronization as well as query processing for XML.

new tool for structuring the design and code of software systems.
 
AOP simplifies development of system aspects that previously were
among the most difficult to handle, including failure handling
strategies, synchronization policies, change propagation, security
checking, distribution, policy enforcment and many others.
 
AOP using AspectJ makes it possible to describe, in just one place in
the system, the implementation of such crosscutting aspects.  This
reduces development time, improves software quality, and makes
software more flexible.
 
This talk will show what it is like to design and implement with
AspectJ, and what implications this has for software developers in
terms of time-to-market, software quality, and product flexibility.

with one another in order to come to mutually acceptable
agreements are likely to become pervasive in the next generation
of networked systems (e.g., Semantic Web, Grid Computing, Pervasive

to participate in a range of negotiation scenarios and exhibit
a range of negotiation behaviours (depending on the context).
To this end, this talk explores the issues involved in
designing and implementating a number of automated negotiators
for auctions, bi-lateral negotiations and persuasive negotiations

Eclipse allows you to independently develop tools that integrate with other tools in a seamless way. Users will not know where one tool ends and another starts. To achieve this goal Eclipse provides a so called workbench that can be extended by plug-ins. This talk starts with a technical overview of the Eclipse architecture, its generic functionality and its key plug-in mechanism.

The phenomenon of emergence involves:

- self-organization of the dynamical systems such that the synergetic effects can occur;
- interaction with other systems from which the synergetic properties can evolve in a new context.

Multi-agent Systems enable cloning of real-life systems into autonomous software entities with a ‘life’ of their own in the dynamic information environment offered by today’s Cyberspace. After introducing the concept of Holonic Enterprise (HE) as a paradigm for the networked world that enables virtual representation of real-life organizations as multi-agent systems I will present a fuzzy-evolutionary approach which mimics emergence in Cyberspace as follows:

- it induces self-organizing properties by minimizing the entropy measuring the information spread across the virtual system/organization such that equilibrium is reached in an optimal interaction between the system’s parts to reach the system’s objectives most efficiently;
- it enables system’s evolution into a better one by enabling interaction with external systems found via genetic search strategies (mimicking mating with most fit partners in natural evolution) such that the new system’s optimal organizational structure (reached by minimizing the entropy) is better then the one before evolution.

The holonic enterprise paradigm provides a framework for information and resource management in global virtual organizations by modeling enterprise entities as software agents linked through the internet. Applying the proposed fuzzy-evolutionary approach to the virtual societies ‘living’ on the dynamic Web endows them with behavioral properties characteristic to natural systems. In this parallel universe of information, enterprises enabled with the proposed emergence mechanism can evolve towards better and better structures while at the same time self-organizing their resources to optimally accomplish the desired objectives.

the subject of R&D and some exist as commercial products.  The GRIDs concept
represents many different things to different people: metacomputing,
distributed computing, advanced networking, distributed database,
information retrieval, digital libraries, hypermedia, cooperative working,
knowledge management, advanced user interfaces, mobile and pervasive

technology as a means to an end - to improve quality, speed of working and
cooperation in their field.  GRIDs will deliver the required information in
an appropriate form to the right place in a timely fashion.  The novelty of
GRIDs lies in the information systems engineering required in generating
missing components and putting the components together.  Ambient
computing provides new possibilities in connectivity of a person (with or
without sensors or data detectors) to a GRIDs environment allowing previously
unimanigable possibilities in informaiton delivery, data colection, command and

IT-Industrie. So stützten sich wesentliche Teile der
Web-Technologie auf Standards ab, die durch offene Prozesse
innerhalb von herstellerunabhängigen Konsortien entwickelt wurden.

Der Trend zur Standardisierung läßt sich jedoch weiter
zurückverfolgen. Bildete internationale Normierung in der Frühzeit
der IT den üblichen Innovationspfad (z.B. ADA, COBOL) so verlor
diese Grundidee mit dem Aufkommen leistungsfähiger
Arbeitsplatzrechner immer mehr an Bedeutung. Dieser Verlust ging
mit einem neuen Ansatz der Vereinheitlichung einher, der nicht
mehr den herstellübergreifenden Konsens in den Vordergrund zu
stellen suchte, sondern die in Standardisierung als internes Thema
Begriff (z.B. IBM, aber vor allem: Microsoft). Als Reaktion auf
die wachsenden Interoperabilitätsprobleme dieser, ohne Einwirkung
des Marktes und der Öffentlichkeit entwickelten, quasi- und
de-facto Standards etablieren sich seit den 1980er Jahren
regierungsunabhängige Standardisierungsgremien wie die OMG und das
W3C, welche mit technischen Foci durch Anbieter und Käufer
gleichermaßen, ins Leben gerufen wurden.

Von diesen Gremien geht aktuell die wirkungsmächtigste Dynamik
aus, welche versucht die Techniken der verschiedensten Hersteller
auf der Basis offener, allgemein akzeptierter und breit
umgesetzter Übereinkünfte zu standardisieren. Ziel ist es hierbei
nicht gleiche Implementierungen zu befördern, sondern die als
wettbewerbstdifferenzierend erkannte Diversifität zu erhalten und
Standards als Brücken zwischen den Herstellerwelten zu etablieren.

The process of software development and evolution is an ambitious undertaking involving a huge number of variables under dynamically changing requirements, processes, actors, stakeholders, tools and techniques. Very often, this is combined with incomplete, imprecise, fuzzy or inconsistent information about all the involved artefacts. The challenge is to provide sound methodological support for enabling good decisions about processes and products, risks and bottlenecks as well as for selection of tools, methods and techniques.
The idea of offering decision support always arises when decisions have to be made in complex and dynamic environments. Support here means assistance for structuring the problem, and for analyzing and verifying the obtained structure. Software engineering decision support systems are an extension and continuation of the software engineering experience factory and learning software organizations approach. In addition to collecting, retrieving and maintaining models, knowledge, and experience in the form of lessons learned, SE DSS generates new insights from on-line investigations in a virtual (model-based) world, by offering facilities to better structure the problem as well in ranking and selecting alternatives.
The talk will present fundamental principles and basic methodology of software engineering decision support. Emphasis will be on the OO and component based software development paradigm.

Things become less straightforward when wait() and notify() have to be employed to realize more flexible synchronization schemes. Using two well-known examples, the bounded buffer and the readers and writers problem, the snares and traps of hand-coded synchronization code and its entanglement with the actual application code are illustrated. Following that, interaction expressions are introduced as a completely different approach where synchronization problems are solved in a declarative way by simply specifying permissible execution sequences of methods. Their integration into the Java programming language using a simple pre-compiler and the basic ideas to enforce the synchronization con-straints specified that way are described.

In contrast to systems like AspectJ, weaving and unweaving in AspectS happens dynamically at runtime, on-demand, employing metaobject composition. Instead of introducing new language constructs, AspectS utilizes the expressiveness of Smalltalk itself as a pointcut language.

When an application is started, the hosting Java Virtual Machine (JVM) gets the required classes one by one as they are needed from these archives. For this purpose, the JVM locates the related byte code taking the names of the class and its package and evaluating the environment setting CLASSPATH. This is well-suited as long as there is only one byte code matching the given class name. However, this procedure is not feasible when the byte code has to be selected among others related to the same class name using properties such as version numbers or manufacturer. In this paper, we introduce so called Java Class Collections which enable the logical grouping of classes separately from their physical deployment within Java Archives and allow tagging them with supplementary properties used to select the right byte code. Finally, we illustrate the application of the approach for multi-application hosting and in remotely composable application systems.

The well-known, published product-line-engineering methods tend to focus on the early stages of the software life cycle and address product line issues at a high-level of abstraction. Connecting product-line concepts with established implementation technologies is thus largely left to the user. This paper introduces a method, known as the KobrA method, which addresses this problem by enabling product line concerns to be coupled with regular (non-product line) architectural artifacts, and thus introduced incrementally. By explaining how the method can be understood as a concrete instantiation of the well-established PuLSEDSSA product-line architecture approach, the paper clarifies the product line features of the KobrA method and illustrates how they can be used in tandem with established, general-purpose product line methods.

Their aim is to process transactions quickly, cost-effectively, and with minimal human intervention. Due to the nature of the financial industry, inconsistencies inevitably appear throughout the lifetime of a financial transaction and their resolution introduces cost and time overheads. We give an overview of requirements for inconsistency detection in our particular domain of interest: the over-the-counter (OTC) financial derivatives sector. We propose a taxonomy for the classes of consistency constraints that occur in this domain and present how xlinkit, a generic technology for managing the consistency of distributed documents, can be used to specify consistency constraints and detect transaction inconsistencies. We present the result of an evaluation where xlinkit has been used to specify the evaluation rules for version 1.0 of the Financial Products Markup Language (FpML). The results of that evaluation were so encouraging that they have led the FpML Steering Committee to consider xlinkit as the standard for specifying validation constraints throughout.

Existing UML diagrams can be used to conveniently model behavior, but these diagrams can be hardly used to model mobility. In this paper we present an extension to UML class and activity diagrams to model mobile systems. We assume that mobile objects can migrate from one location to another. Locations can be nested and mobile too.We introduce stereotypes to model mobile objects, locations, and activities like moving or cloning. We introduce two notational variants of activity diagrams for modeling mobility. One variant is location centered and focuses on the topology of locations. The other one focuses on the actor responsible for an activity. We compare these two types of diagrams and define a metamodel for them.

In this paper, we present a framework for resource management and information storage in P2P networks. Our framework aims at providing an easy to use and flexible model for P2P computing encouraging more modularised application development and permitting reuse of components. Efficient localization of resource and representation of information are central needs of P2P applications. To address this need our resource management framework (RMF) forms a distributed in-formation space enabling not only at storage of information but forming graph structures that can be used to build new kinds of applications enabling the users to browse the contents of a P2P network.

Unfortunately, integrating existing components practically means reuse (i.e., adaptation and use) rather than use only, which makes a clean, ideal component-based development hard to realize in practice. Product line engineering, however, is an approach that tackles this problem by making components systematically as generic as needed for a particular product family and thus allows components to be reused easily within a family context. Making a component generic means a component covers variabilities among systems in the family and thus that its implementation must consider variabilities. In this paper, we describe a process for implementing generic product line components and give an overview of variability mechanisms at the implementation level. The proc-ess, as well as the described variability mechanisms, is illustrated by a running example, a generic test compo-nent.

The current use of entity beans for persistent data storage has a number of weaknesses. Component level inheritance and dynamic querying are not supported appropriately, and the whole approach seems to be overweight. In order to overcome these weaknesses, we implemented a JCA-compliant resource adapter, which enables the use of Java Data Objects (JDO) instead of Entity Beans and allows the introducuction of a lightweight, easy to use and powerful transparent persistence layer for the Java 2 Enterprise Environment (J2EE).

This paper describes the design and prototypical implementation of a simple, lightweight communication infrastructure specifically targeted to devices with limited resources. One of the central ideas of the infrastructure is to encode both remote procedure calls and user interface abstractions in XML format which provides a broad range of interoperability. In addition, we rely on simple, easily implementable software components in order to adapt the architecture to a large variety of small devices without having to resort on proxy technologies or virtual machines in extremely memory-restricted systems.

Such software is only possible due to the impressive success of the hardware developers. The main reason for this trend is the user's demand for new gimmicks driving the software developers to include all possible features into their systems. Those features are all loaded every time the program is executed and make the system bulky. The fact that most add-ons are simply integrated without a clear interface only adds insult to the injury.
This paper shows a way to design software which helps to battle this development of bulky systems. The well-known plug-in concept is formally described as a design pattern. Based on this pattern a development principle is proposed. As a special case, GUI development is treated in more detail.

It is, therefore, essential that database support be extended to new programming paradigms as and when they emerge. This paper proposes an approach to support the storage, reuse and mining of aspects - constructs used in Aspect-Oriented Programming (AOP) to separate crosscutting concerns - in AspectJ (an aspect language for Java) using a relational database. The approach is based on mapping an aspect's anatomy to the relational model hence allowing fine-grained queries to be composed. This results in greater flexibility during search and retrieval in contrast with most existing code repositories which store the code as BLObs comple-mented by meta-data about the code.

To support capturing and re-establishment of distributed execution-state, we developed a byte code transformer that adds this functionality to a Java application by extracting execution-state from the application code. An important benefit of our mechanism is its portability. It can transparently be integrated into any legacy Java application. Furthermore, it does require no modifications to the Java Virtual Machine (JVM) or to the underlying Object Request Broker. Our mechanism can serve many purposes such as migrating execution-state over the network or storing it on disk. In particular, we describe the implementation of a prototype for re-partitioning distributed Java applications at runtime. Proper partitioning of distributed objects over the different machines is critical to the global performance of the distributed application. Methods for partitioning exist, and employ a graph-based model of the application being partitioned. Our mechanism enables then applying these methods at any point in an ongoing distributed computation.

While the required technologies for a component-style system development are widely available, for instance Sun_s Enterprise Java Beans, a problem inhibits the breakthrough of the component paradigm in business application domains: com-pared to traditional engineering disciplines there is a lack of standardized methods to describe business compo-nents. Such a description has to address several aspects: What services are offered and requested by a business component? How can these services be used? Are there any interdependencies between the services of a set of business components? What quality characteristics do the offered services fulfill? And so on. In this paper, we present a holistic approach to specify a business component. This approach consists of seven specification levels which address both technical and business aspects. Furthermore, we show the application of this method by specifying a simple business component that deals with German bank codes.

This dependence on technology enables innovative business models, but also demands that supporting software systems are developed alongside careful consideration of the company's future strategy and business models. This paper presents a new approach to semi-automated component-based evolution of eBusiness support systems. The process is automated by linking business strategy with software structure using mappings between business process patterns and software patterns. Identified software patterns are used to guide the procurement of appro-priate components using software "test harnesses". A strategic positioning and planning tool, the eBusiness Ma-turity Model (eBMM) is used for the strategic level input by positioning a company depending on which business processes are automated, and then planning the future extensions of software support to progress up the EBusi-ness maturity levels. We illustrate the use of this model in an eCommerce start-up and show how the model guides the procurement of software components to support mission-critical parts of the business whilst enabling future growth in the marketplace.

Together with the success of the Internet technology, it is often necessary to offer a web-based software solution. For Java development, J2EE builds a bridge from traditional towards web application development. With Java Server Pages and Servlets it is possible to implement web sites with dynamic content. Using these techniques, it is possible to apply well-tried programming paradigms, e.g. the Model-View-Controller (MVC) paradigm. With regard to software quality as well as adaptability, unit testing has become more and more important during application development. It provides a powerful technique to develop new functionality as well as to change existing parts. This is also strengthened with success of Agile Processes that force a test-driven development. From there, appli-cation code grows up with unit tests from scratch on.
For Java, JUnit has become the de-facto standard unit test environment that supports a test-driven approach for traditional software development quite good. Nevertheless, web application development requires broadening the unit test approach. Both, the scope of the unit tests as well as the JUnit framework, have to be extended to enable unit tests considering the special requirements of web application development. In this paper, we present an ap-proach to customize the unit test approach as well as the JUnit Framework towards a test-driven web application development.

The have to be enriched by detailed behavioral information in order to be used for statistical test case generation.
This paper introduces an approach for generating sys-tem-level test cases based on use case models and refined by state diagrams. These models are transformed into usage models to describe both system behavior and us-age. The method is intended for integration into an iterative software development process model. The resulting test cases are suited to be carried out in conventional ways, i.e., either manually or using test tools. The method is supported by a XML-based tool for model transformation.

Lightweight, 'agile' software development methods are not a replacement for traditional, heavyweight methods. But under certain assumptions, they are a welcome alternative in many areas of software development. In this paper, we outline the differences between agile and traditional approaches of software development and examine how development tools are used in the latter. We consider experience from industrial projects as well as results found in the research community. Then we discuss the requirements which agile methods and development processes impose on development tools and show how existing tool technology can be used to build agile tools. These tools allow agile methods to evolve through suitable tool support.

In order to judge the risks in a situation and initiate precautionary actions, future systems have to possess the capability to predict the behavior of surrounding traffic participants. This paper outlines an approach to predictive situation analysis for driver assistance systems and discusses one key issue in more detail - namely the predictive action recognition. In this context, a situation representation formalism will be introduced that exploits time as a compact physical measure. Furthermore, it will be shown how probabilistic networks can be used for reasoning about driver (action) intentions and how such networks can help to cope with uncertainty resulting from inaccuracy in models and sensor data. First results are shown in simulation for highway overtake scenarios. In the situations presented the prediction for an upcoming lane change can be made by the assessment of the time gaps to the nearest neighbors of that specific vehicle.

This development methodology requires that the
application’s task set and the characteristics of each task – execution period,
worst case execution time, etc. – are previously known. Although leading to
proven systems, the adaptability to changes in the system’s architecture is quite low, due to the static nature of the design. In the area of distributed real-time systems, complex applications are arising where the need for adaptation and flexibility can not be ignored. The concept of agent based software development is proposed as suitable to cope with the complexity of such systems, providing intrinsic characteristics of autonomy and self-regulation. As example, an automotive electronic control system is presented, as well as the vision of an agent based approach to the scenario.

cardinality, and communication syntax/semantics. Analytical planning approaches
were usually designed for specific domains and therefore are relative domain-depend.
In this work, these difficulties are addressed through a generic algorithmic approach, namely the Co-evolutionary Planning (CEVOP) methodology, which provides a planning mechanism for multiple co-operating and/or competing homogeneous and/or heterogeneous agents through a single co-evolutionary algorithm. CEVOP is rather a framework for mapping the planning problem from the multi-agent domain onto the co-evolutionary algorithm domain, in order to find concrete plans to be executed later by the agents co-operatively and/or competitively.

This paper presents an approach of negotiation using fuzzy reasoning, in particular fuzzy backward reasoning. A fuzzy collaborative agent has local knowledge in the form of a fuzzy model. Fuzzy backward reasoning is performed based on the fuzzy model to generate and modify an action plan in each agent.

applied this within a community of Buyers and Sellers in a simulated car hire
scenario. An automated negotiation environment has been developed and the
various negotiation algorithms made to compete against each other. In a single
tournament, each algorithm was used as both a Buyer-negotiator and a Sellernegotiator.
Each negotiating algorithm accommodates the parameters for negotiation as a set of desirable goals, represented as examples of product specifications. It was the task of each negotiating algorithm to get the best deal possible from every one of their opposites (i.e. Buyer versus Seller) in the sense of being close to the examples they were given as goals. One algorithm proved to be superior to the others against which it was made to compete.

This system consists of various autonomous agents which have the capability of communicating with each other and making decisions based on its knowledge. An iterative bidding mechanism is proposed to facilitate the process of job assignment to machines and handle the negotiation between agents. This mechanism enables optimum process plans and production schedules to be produced concurrently. A currency
scheme is proposed to encourage or prohibit machine agents to put forward their bids. To deal with the optimisation problem, i.e. to what degree and how the currency values are adjusted in each iteration, a genetic algorithm (GA) approach is developed. This system is implemented in a Java platform. A test case is used and the results will be discussed in this paper.

As traditional process planning and production scheduling operate independently for process plans and production schedules generation respectively, production schedules generation processes become inflexible and is restricted by the pregenerated
process plan. In response to this issue, a multi-agent Monte Carlo configuration and optimization method is proposed to integrate process planning, production scheduling, and resource optimization for concurrent
evaluation of planning and scheduling options. The principle of this
methodology is to integrate agent bidding mechanism and Monte Carlo optimization, in which agents perform iterative interactions to evaluate
production decisions dynamically for an optimum solution determination.

These examples are analyzed with respect to common values of the organizational variables ‘goal orientation’, ‘coordination’ resp. ‘co-operation’, ‘division of labor and allocation of work’, and ‘delegation and responsibility’.
Particularly, depending on the situational variables ‘information availability’,
‘environmental dynamics’ and ‘problem-complexity’ these organizational
variables show typical ranges. Thus, a common framework is established in
order to classify multi-agent systems for their ability to solve business
problems.
In recent decades principal-agent-theory has turned out to be one of the most
prominent theoretical foundations of management science. Applying this theory
to the application of MAS in enterprises, an improved and theoretically guided
understanding of deficits of MAS applications will result. Combining these
insights with the situational variables ‘information availability’,‘environmental dynamics’ and ‘problem-complexity’ most promising research areas for future applications are identified.

In this context, the system that allows controlling the production has to be a modular, flexible and reactive system. The hierarchized and classical approaches don’t permit any more to take into
account the complexity linked to such system. That’s why, we propose an
approach, which has reactive, distributive, and emergent properties to control
the system of production, based on multi-agent system principles. After having
introduced the context and reasoning work, we describe the different parts of
our multi-agent model. Lastly, we illustrate this approach on a practical

In this paper, assuming a Distributed approach to Knowledge Management (DKM), is proposed that technological and social architectures must be reciprocally consistent.
Moreover, in the domain of Knowledge Management, technological architectures
should be designed in order to support the interplay between two
qualitatively different processes: the autonomous management of knowledge of
individuals and groups - here called Knowledge Nodes (KNs) -, and the coordination required in order to exchange knowledge among them. Finally a peer to peer architecture to support knowledge exchange across distributed and
autonomous KNs is presented.

specification. The concept of social commitment policies, which govern various
aspects of group behaviour, including penalties for individual acts in the context of group activities, is at the heart of this model. The concept of penalty is presented as an important concern in light of the assumption that, even conceived as society members, agents are still autonomous, so they can violate the established social commitments. The different types of social commitment policies are classified, and the interest of their application not only as an organisational abstraction but also as a mechanism for specifying the expected behaviour of the agent society is discussed. It is also shown how deontic, action and temporal (DAT) modal logic will be used in the formal specification of the different types of policies and their related concept of violation. This formalisation will allow agents to reason deliberatively about the existing social norms, the responsibilities proper to their position and the consequences of violating these responsibilities. Finally, attention is paid to the formalisation of policy dynamics by means of illocutionary logic.

These models are parts of a layered architecture which separates the aspects regarding the communication from the decision activities of the agents. By this, application independent conversation protocols are defined. The application dependent parts of the model are formed by a sequence of activities an agent has to perform to solve a problem. The different layers of the architecture are separated from each other by well-defined interfaces.

As this occurs, the nature and extent of human interaction with computers will alter correspondingly. Although the characteristics of interaction cannot be fully anticipated, it is clear that as sy stems gain intelligence and autonomy, the demands placed on them will become more exacting. To meet these expectations, the Semantic Web should incorporate work-centered services. These services will provide focused, intelligent points of contact between the Web and its users. Users will access work-centered services to formulate and conduct investigations, and to collect, organize, and analyze results. Work-centered services will direct tasks in behalf of the user and communicate with the user in a humanly coherent manner. As a result, the concept of the user interface will broaden and deepen to include specialized agents, possessing the expertise to assemble information for end-user consumption. These agents will occupy the web-continuum just as any other knowledge resources.
This paper introduces the concept of work-centered services and describes related research and development being performed as part of the KnoWeb project.

little practical experience about the use of agents in such a demanding environment exists. Nowadays automation systems face new challenges and therefore new concepts are needed to meet them. This paper presents a vision of using agents within industrial automation systems from the point of view of automation engineering. To this end, the characteristic structures of automation systems are analyzed and opportunities, as well as advantages, of applying agentoriented concepts are investigated. A possible approach for the integration of a multi-agent system into existing automation systems is introduced and illustrated by an application example.

The architecture provides a suitable decision-making framework where each agent represents a node in the hierarchic tree of manufacturing systems such as the company as a whole, each plant within the company, each cell or line within the plant, each machine in a cell or line. Each agent has the ability to perceive and evaluate changes that occur in the manufacturing environment, interact with other agents in the system in order to reach an optimal decision, and act based on that decision. In other words, agents respond timely to unexpected changes by continuously co-ordinating their activities, and allocating manufacturing resources dynamically based on actual shop-floor situation. The flexibility of this architecture also lies in its ability to accommodate both homogenous and heterogeneous agents, and its capability for the dynamic addition and removal of agents using a conceptual intelligent communication mechanism similar to the blackboard messaging system.

team as a collective abstract attitude, in which is embedded a novel way of
solving problems and conflicts in our domain. We argue that this collective
attitude is further decomposed into the individual attitudes of the agents
towards various team attributes (Team definition, team methods … etc.). We
then evaluate the different types of the agent teams in a simulated fire world
using teams with and without different types of attitudes. The application and
implementation of this model to a virtual fire world has revealed a promising
prospect in developing team agents.

It is especially interesting taking in consideration the fact that centralized systems appeared later than pure peer-to-peer systems did, but very soon pushed the peer-to-peer completely out of the scene. The _killer_ application that would prove the 100% necessity of fully decentralized systems or their 100% benefit in comparison to the centralized systems is still not found as it was not found 30 years ago when the first peer-to-peer systems appeared. Nevertheless, we do talk about peer-to-peer today as about technology of high importance. We do not want to dedicate this paper to the search for a killer application for peer-to-peer technology or to attempts to find the ways to replace the centralized systems. Instead, we will talk about other class of systems _ _ad-hoc_ _ and about peer-to-peer as enabling technology for ad-hoc systems. We would like to analyze why do we need ad-hoc systems, discuss their features and requirements, and based on this analysis discover the opportunities of peer-to-peer networking. We also provide a list of requirements to the peer-to-peer systems as well as to the existing network technologies that need to be fulfilled in order to fully enable ad-hoc networking in the future.

The original meaning of the term Web services is not to publish software services to the Internet. Web services means _Web of services_, distributed applications assembled from a web of software services, a new way of constructing software: language, platform and location independence.

The presentation provides an overview on the technical foundations and the current state of Web services technology and will further examine some candidate software services in the area of a corporate intranet.

The focus of the presentation: Software systems solve real world application problems. Since the real world is changing, software systems have to be adapted or often completely reconstructed to reflect those changes. To overcome this maintenance problem, dynamic adaptability has to be an inherent property of a software system. That is the idea behind Dynamic Web Services

Kernaussage: In einem Zeitpunkt, in dem eine stabile mobile Dateninfrastruktur besteht, beginnen Unternehmen sich für die Mobilisierung der Geschäftsprozesse zu interessieren. Ziele sind Kosteneinsparung, Produktivitätssteigerung und Erhöhung des Servicegrads beim Kunden.

Herausforderungen: Mobile IT Lösungen werden an der Schnittstelle von mobiler Datenübertragungstechnologie (GPRS, UMTS, Bluetooth, WLAN, etc.) und den bestehenden IT Systemen gesucht. Vor allem muss eine Mobilisierung aber intelligent, selektiv und einfach sein - "SAP/R3 auf einem kleinen iPaq funktioniert nicht - allein schon aus Sicht des Benutzers". Gleichzeitig muss Mobilisierung pro-aktiv sein: Mit Hilfe von einfachen Instrumenten, wie z.B. SMS oder Kalender-Alerts, können Mitarbeiter über kritische Änderungen informiert werden. Schneller, zeitgenauer Push von Informationen statt Pull.

Beispiel für eine erfolgreiche Mobilisierung anhand eines konkreten Business Cases: Der internationale Chemiekonzern DSM

Die bedeutet für junge Softwareunternehmen: Opportunities!

It is easy to discuss Web services, but the actual act of integrating services can be extremely complicated. This session will discuss interoperability between Web services, J2EE and CORBA "from PC's over Unix to the Mainframe" highlighting the following technologies:
 The exposure of Enterprise Java Beans (EJB_s) as Web services
 The exposure of CORBA Objects as Web services
 The interoperability of CORBA and Enterprise Java Beans: CORBA calling EJB_s, EJB_s calling CORBA including CORBA based mainframe integration.
How do all these technologies communicate? 2-Phase Transactional interoperability becomes increasingly important as more computer languages are developed; security (incl. HTTPS, SAML/XKML, CSIv2, TLS/SSL, RACF) also becomes an issue as the technologies are used to transfer sensitive materials that need to remain private.

This presentation will include a demo of Web services technology interoperating with J2EE and CORBA technology, presenting an overall application server platform example. Also included are both, integration architecture and _hands on_ real world project samples.

insights into the dynamic nature of the development process and a better understanding why it is so difficult
to keep the process alive. It shows the fight between order and chaos, chaos that can make a software system
so immobile that the search for solutions and the learning process (that mean the ability to adapt the models
to new insights and keep them synchronized) come to an end.

Due to their flexibility and neutrality regarding programming languages and providers, Web Services are becoming increasingly important in all areas of commercial technology, and thus may be viewed as a mainstream development within IT.

Despite of all optimism and the obvious fundamental possibilities, the introduction barrier of this technology, which is created by established - even though often inefficient – procedures, and the inclusion of legacy systems should not be underestimated. Effective migration approaches and mechanisms to comprise today’s IT landscape are required. Only then Web Service technology will experience a true market breakthrough after initial success reports of early adopters.

This article gives an overview of the current situation with Web Services both from a technical and an economic point of view. After a brief introduction of the basic principles, a closer look will be taken into what is available right now and what is under work or can be expected as far as the level of standards in the near future is concerned. Furthermore, Web Services sometimes considered as the ultimate way of process and system integration, are compared with other XML-based approaches like ebXML and RosettaNet.

With our explanations we try to bridge the arch of today’s Web Services technology and previously used mechanisms, and demonstrate how, by the help of modern integration tools, the hurdles of migration and mixed environments can be overcome, and how the required integration of new and legacy systems can efficiently be realized.

As application development grows from basic J2EE elements like Java Server Pages (JSP's), Servlets and basic Enterprise Java Beans (EJB) more and more J2EE applications will use the whole spectrum of J2EE features.

Moreover, new applications will demand _peer to peer_ secure (and may even secure, 2-PC-transactional) interoperability amongst J2EE Application Servers and backend systems, especially existing mainframe systems with their huge IMS/CICS-based COBOL/PL-I applications. Such systems are may integrated by means of CORBA, JCA, JMS etc. Larger companies, especially, use such features within their enterprise wide application systems.

This talks will present, how all these technical elements can be secured in an overall enterprise security platform. It gives an verview about the relevant security standard elements, thus:
- Web Services security based on XKML. SAML
- CORBA-based secure interoperability based on CSIv2, TLS/SSL
- J2EE 1.3 security features (J2EE basic authentication & authorization, JAAS)
- Integration with RACF authentication for the mainframe

As an overall example serves IONA_s Security Platform (ISP), which is a fully standards-based solution, which allows to secure all the mentioned elements within the Orbix E2A integration platform. ISP provides a _plugin architecture_ for security, which easily allows to interface with the enterprises existing authentication & authorization systems like Siteminder, Entrust etc. as well as with different cryptographic libraries. The ISP is not limited to IONA_s integration solutions, but allows to integrate e.g. with other J2EE application servers and CORBA implementations as well.

don’t enable the rapid implementation of agents from reusable components.
This is because of the underlying problem that the agent-oriented programming
paradigm, defining how abstraction, decomposition, and modularity
are achieved, is not sufficiently understood or developed. This paper presents
an agent decomposition framework that offers agent-oriented programming and
software engineering separation of concern guidelines in the context of proposing a more flexible and extensible internal agent architecture than current MAS frameworks provide. This architecture provides an infrastructure that supports constructing agents from reusable components at the subsystem level. Subsystems are added to an agent through a dynamic description, event, and ontology registration process. Once connected, the composite subsystems interact by an event-based software bus that acts as the central nervous system of an agent. This gives subsystems the ability to reason about the functionality and current state of their constituent parts and allows agents to be composed from industry wide best known components instead of building agents from a single MAS framework repository.

They use hierarchical reactive plans to perform arbitration between their component modules. BOD provides not only architectural specifications for modules and plans, but a methodology for building them. The BOD methodology is cyclic, consisting of rules for an initial decomposition and heuristics for revising the specification over the process of development.

This paper argues for using stepwise feature introduction as a building methodology for reliable cooperative
agent systems, and explain how to resolve feature ordering and feature interaction problems between different layers when implementing agent systems by this approach.

Now, both communities tend to foster the gap. Our work is part of this trend, by exploring the notion of situated composition, where each agent or component can have its own compositional perception of the rest of the system, and by considering that an agent is actually an extended component. We achieve agent dynamic composition in terms of delegation and agent proxies. This way, component aggregation accounts for synchronization and existing interaction patterns. Agent conversations are the natural canvas supporting compositional relationships, and agents are recursively decomposable, without having to introduce other organizational constructs that might disturb agents fundamental properties.

The system should reach some goals and provide specific requirements. The designer should produce an accurate model for the domain ontology, the agents’ knowledge and interactions. The structural and behavioral description of the system will descend from these elements and will also generate some constraints in the other parts of the design.
From these considerations and our experiences in designing MAS with a CASE
tool supported methodology (PASSI) we deducted the importance of exploring
the design process of these systems from several different perspectives that
explicitly address the architectural, social, knowledge, resource and physical
aspects of them.

Robustness can be achieved through redundancy, and we hypothesize that agents are an appropriate unit for adding redundancy. As part of our investigation, we asked 53 students to independently build one agent for a simple Multiagent domain.
We did a comparison study between the different student’s agents while working with each other independently and while working with each other as part of collaboration. A simple decision-making mechanism was also introduced and compared. This influx of redundancy in the collaborations provided a discernible increase in productivity. The results shown here should lead to further rich and enlightening research into agent-oriented software engineering.

The need of a quality software engineering approach to their
design arises together with the need of new methodological ways to address
important issues such as ontology representation, security concerns and
production costs. The introduction of an extensive pattern reuse practice can be
determinant in cutting down the time and cost of developing these systems.
Patterns can be extremely successful with MAS (even more than with objectoriented systems) because the great encapsulation of agents allows an easier identification and disposition of reusable parts. In this paper we discuss our approach to the pattern reuse that is a phase of a more comprehensive approach to agent-oriented software design.

A host of standards are being developed in this respect, aiming at
easing and promoting interoperability between heterogeneous agents and multiagent systems. The work of the FIPA is prominent in this field. The effort of this organization centres on defining an abstract architecture that identifies all the elements involved in achieving the above-mentioned interoperability and establishes the relationships between these elements. Nevertheless, this model does not completely address the inherent social-ability of any multi-agent system and which is especially important for achieving a higher level of interoperability. This paper lays the foundations for an extended role model and an organizational model that will serve as a framework for establishing and specifying relationships between heterogeneous agents interacting in an open environment. The agent and agent information models proposed by the FIPA are adapted and extended to accommodate this social viewpoint and social requirements on agent conversations and communication languages are discussed. We then propose a policy framework that constitutes the basis for agent social infrastructure management. Finally, the most relevant platform service infrastructure needed to support the policy framework is presented and defined. Our aim is to be able to model how agents are going to interoperate with one another within an open environment by means of normative policies, and how this environment will be organized and supported.

The agent-oriented paradigm can be considered a natural extension to the object-oriented (OO) paradigm. Agents differ from objects in many issues which requires special modeling elements. Although there is a well-defined OO analysis and design modeling language (UML), agent-oriented development has neither a standard analysis and design modeling language nor a standard development process. In this paper, we propose a software engineering process for agent-oriented analysis and design. The process is based on existing object-oriented software engineering concepts. We also extend the Unified Modeling Language (UML) to model agents.

to the activities that precede the specification of the prescriptive requirements, such as understanding how the intended system would meet the organizational goals. This is obtained by means of the two requirement phases: the early requirements analysis and the late requirements analysis. Moreover, Tropos uses, along these phases, a uniform notation and an homogeneous, smooth, incremental, and iterative process, based on a set of progressive transformational steps.
This paper will take into account the application of the Tropos methodology to a
self-motivating case study: the definition of a support tool for the Tropos methodology itself. The focus here is on the early requirements and on how to manage the transition from them to the late requirement analysis.

For instance, new communication channels need to be deployed, new user-friendly services need to be suggested, and new types of computing resources need to be involved. In addition to the traditional challenges of mobile computing, the following issues are addressed in SAMOS: How to discover m-services in an open wireless environment? How to compose m-services to create sequences? And, how to make m-services runnable on wireless devices?

Static offer schemes assume that all users have the same criteria which may not meet the requirements of all potential buyers. A fixed price might not always refect the current market balance of supply and demand and the specific valuation of a single buyer. In this paper we propose an agent-mediated insurance brokering system using a flexible negotiation model that includes multi-attribute bidding as well as some kind of learning capabilities. Moreover, in the core of the provided brokering facility, we are using conceptual clustering procedures as an approach to better match customers and insurance product offers providing a valuable add-on to both customer's and sellers' sides. Intelligent agents engage themselves in a negotiation process by exchanging proposals and counter-proposals trying
to convince opponents to modify their bidding values. We are now developing a Java based multi-agent infrastructure specifically dedicated to the insurance e-commerce domain, exploiting Toshiba's Bee-gent framework. For both acceptability and generalisation purposes, XML (including appropriate ontology-based messages) has been chosen as our agent communication format.

Web services are self-contained, self-describing, modular applications that can be published, located, and invoked across the Web. Web services perform functions that can be anything from simple requests to complicated business processes. This paper proposes an approach based on software agents to integrate the Web services in Internet. Software agents can significantly improve the design and the development of Web applications thanks to their characteristics of autonomy and adaptability to open and distributed environments. For example, Customers can employ software agents to help them identify, locate and procure the products and services that they require. They can also empower and trust their agents (to varying degrees) to negotiate electronically with providers and/or their agents in order to buy and sell products and services within a complex multimedia information trading system. The aim of this paper is to show the advantage of the introduction in the Web services infrastructure of software agents for the autonomous management and coordination of the integration and query processes over Internet.

However, when later teams approach the system it may not be obvious why particular decisions have been taken. This problem is particularly acute in the case of designers attempting to integrate services from many different service providers. In this paper a mechanism for recording these decisions is described. We illustrate how design decisions can be captured and how these abstractions can then be used in as the basis of reuse in an extension of the Zeus agent toolkit.

Determining matching components of database or XML schemas is needed in many applications, e.g. for E-business and data integration.
Various schema matching systems have been developed to solve the problem semi- automatically. While there have been some evaluations, the overall effectiveness
of currently available automatic schema matching systems is largely unclear. This is because the evaluations were conducted in diverse ways making
it difficult to assess the effectiveness of each single system, let alone to compare their effectiveness. In this paper we survey recently published schema matching evaluations. For this purpose, we introduce the major criteria that influence the effectiveness of a schema matching approach and use these criteria to compare the various systems. Based on our observations, we discuss the requirements for future match implementations and evaluations.

Ill-structured design of Web sites also prevents the users from rapidly accessing the target pages. In this paper, we describe two complementary approaches to Web usage mining as a key solution to these issues. First, we describe an adaptable recommendation system called the system L- R, which constructs user models by classifying the Web access logs and by extracting access patterns based on the transition probability of page accesses and recommends the relevant pages to the users based both on the user models and the Web contents. We have evaluated the prototype system and have obtained the positive effects. Second, we describe another approach to constructing user models, which clusters Web access logs based on access patterns. The user models also help to discover unexpected access paths corresponding to ill-formed Web site design.

However, a solution should also consider client-side cache management for the XML data, synchronization of concurrent access to the XML data, and lost connections during transaction execution. In order to reduce data exchange between client and server, our protocol re-uses data stored in the client’s memory instead of reloading data into the client’s memory wherever possible. A key idea is that the server keeps a ‘living copy’ of the XML fragments in the client’s memory for efficient cache management. Furthermore, our protocol integrates well with a validation based scheduler in such a way that offline work and transaction completion after lost connections are sup-ported. Finally, we present some optimizations that further reduce client-server communication.

While much attention has been paid to performance issues, far less work has been done to address one of the fundamental issues of semistructured data: schema evolution. Semistructured indexing and storage solutions tend to end where schema evolution begins. In practice, a real promise of semistructured data management will be realized where schemas evolve and change. In contrast to fixed schemas, we refer to schemas that grow and change as open schemas. This paper addresses the central complications associated with indexing open and evolving schemas: we specify the features and functionality that should be supported in order to handle evolving semistructured data. Specific contributions include a map of the steps for handling open schemas and an index for open schemas.

A metaphor for this approach views queries as patterns, answers as data items matching the queries. Formally, an answer to a query is defined as a simulation of an instance of the query in a data item.

WrapIt: Automated Integration of Web Databases with Extensional Overlaps 54 ws webdb The world wide web does not longer consist of static web pages. Instead, more and more web pages are created dynamically from user request and database content. Conventional search engines do not consider these dynamic pages, as user input cannot be simulated, thus providing often insufficient results.
A new approach for online integration of web databases will be presented in this paper. Providing only one sample HTML result page for a source, result pages for new requests will be found by structural recognition. Once structural recognition is established for one source, other web databases of the same universe (e.g. movie databases) can be integrated on the fly by content-based recognition. Thus, the user receives results from various sources.
Global schemata will not be produced at all. Instead, the heterogeneity of the single sources will be preserved. The only requirement is given by the existence of an extensional overlap of the databases.

An enhanced indexing scheme at the architecture's core supports quick identification of structural node relationships. Based on this scheme, we extend the application of path join algorithms to implement most parts of the XPath query language specification and add support for keyword search on element and attribute contents.

Publication and query are performed by utilizing UDDI’s Application programming interface (API), which employs SOAP as a communication instrument. By offering an invocation API in addition to two other types for examination, UDDI allows clients to search for and subsequently invoke specific Web services. Failures in invoking already sought and, on the application side, statically cached Web services typi-cally result in re-querying the registry.
However, an application’s reaction time in response to changes is limited due to UDDI’s replication latency, i.e. the amount of time it takes for changes to entries stored inside the UDDI repository to be propagated to all UDDI nodes.
This paper proposes a mechanism termed active UDDI, which al-lows the extension of UDDI’s invocation API in order to enable fault-tolerant and dynamic service invocation.

This next wave of the internet era is being driven by a concept named Web services. The Web services technology provides the underpinning to a new business opportunity, i.e., the possibility of providing value-added Web services. However, the building of value-added services on this new environment is not a trivial task. Due to the many singularities of the Web service environment, such as the inherent structural and behavioral heterogeneity of Web services, as well as their strict autonomy, it is not possible to rely on the current models and solutions to build and coordinate compositions of Web services. In this paper, we present a framework for building reliable Web service compositions on top of heterogeneous and autonomous Web services.

We argue that more adequate specifications can be built on the notion of depen-dency of activities and coordination activities to manage these dependencies. We
propose a Dependency Markup Language to capture dependencies amongst ac-tivities
and generalizations/specializations amongst processes. With that, we can
describe composite services at more suited levels of abstraction and have several options to use such descriptions for service coordination, service discovery and service classification.

Recently, we have witnessed the emergence of web-service description and request languages as well as composition protocols. Transaction management is crucial for implementing reliable and robust web-based business transactions with cohesive web-services.
However, existing service composition protocols tend to provide minimal support for transaction management. This support basically mimics traditional database mechanisms for ensuring ACID-properties of web-services, apparently in an arbitrary way. Ergo, sound theoretical underpinnings for incorporating transactional acidity in web-service composition languages is currently lacking.
This paper outlines a theoretical three-dimensional framework for ACID criteria of e-business transactions. This framework serves as the foundation of a transaction model that relies on “traditional” atomicity spheres.

This paper analyses possible contributions of the emerging Web service archi-tecture to settle open issues that both application integration as well as compo-nent-based application development have in common and thereby focuses on
the specification of components. Within the Web service architecture, specifica-tion is standardized by the UDDI framework, which is at first analyzed based
on some general requirements for specification frameworks. Hereafter various
extensions to the UDDI framework are proposed and elaborated in detail. They
improve the specification of Web services by providing additional information
about various aspects: security, performance, behaviour, coordination, imple-mented terminology (semantics), and implemented processes (pragmatics). Ac-cordingly, a mix of specialized (formal) notations for the particular specifica-tions is proposed. The resulting specification framework is ordered using a
thematic grouping that consists of white, yellow, blue and green pages.

Besides the three standard roles found in current frameworks (i.e., the service provider, the service requestor, and the service registry), our approach introduces an additional role that we call the service notifier. The framework is designed in four layers: the Proxy Layer, the Web Server Layer, the Application Notification Server Layer, and the Application Worker Layer. Since the WSNF itself is a service provider, this framework is reflective in the sense that it checks and notifies itself about changes. The framework is documented using design patterns. The set of patterns applied in the framework design includes the following patterns: the singleton, the delegation, the factory method, the observer, the mediator, the notifier, which is a combination of the mediator and the observer, the item description, and the proxy. The notifier pattern is in fact a publisher-subscribe pattern with push semantics. The framework uses a requestor profile to support notifications related to a category of events related to changes, failures, and version control problems of Web services.

Agents_ autonomy allows the execution plan to react dynamically to estimation errors without being penalized by time overheads that usually results from the use of a centralized monitor. Performance evaluation shows the benefits of this approach for standard hash join algorithms. Response time can significantly be reduced : from 3% to 60% when the error on selectivity factor exceeds 40%, and from 11% to 400% when estimation error on the size of a temporary relation is greater than 30%. Performance results serves as a basis for the definition of a strategy for agent mobility.

Since most of the data is stored in relational tables, there must be a way to transform relational data into XML. For a XML document to be readable for every business associate relational database, a mapping must be provided to specify how a XML document fits a specific database model. This paper proposes AXIS (Automatic XML Interchange System), which is an architecture implemented in Java that allows the creation of such mapping and, afterwards, the conversion of relational data to XML and back to relational data.

and condensing the time of software product lifecycles. However, building
reusable and stable analysis patterns is still a challenge. This paper proposes
the novel concept of Stable Analysis Patterns as a new approach for building
stable and reusable analysis patterns. In addition, it introduces eight essential properties to evaluate analysis pattern reusability. This paper contrasts stable analysis patterns with some analysis patterns using the proposed properties.

]]> Hamza, H Hamza, H Hamza Haitham University of Nebraska-Lincoln hhamza@cse.unl.edu Concepts_for_a_Produ ckoerner 15.10.2002 10:59 25 final Concepts for a Product Line Knowledge Base and Variability. 59 ws gcse This paper presents the basic ideas of constructing a product line
content & knowledge base on top of arbitrary configuration management sys-tem.
Its need stems from the fact that evolving product lines arise a number of
significant challenges, which can only be mastered with sound information
base. The complexity of a product line engineering and its sheer number of ad-ditional artifacts and methods aggravates the intellectual control of a product
line and its change over time. Management activities like product design, building of road maps or effort estimation become more difficult than for single product engineering and ask for more sophisticated information. We think that the problems can be solved with the explicit depiction of product line content & knowledge. Only then we can understand and control how a product is constituted from single software artifacts, what are their dependencies and relations, and how changes on shared assets affect the products in a product line. The product line content & knowledge base is a prerequisite for product line management services and processes, which makes it possible to manage the evolution of a product line and to control its consistency and completeness.

In particular much research has focused in topics raised by class evolution either through coercion or versioning. In this paper dynamic attribute addition in terms of versioning is addressed. Dynamic attribute addition in this context concerns modifications of variables of objects and classes at runtime. As a means to an end an approach based at the notion of metaclasses is
proposed. Finally an evaluation of the benefits and the drawbacks that emerge from its use is established.

The Internet - a Meta FIS in one sense - demands for the ability to query many different information sources. Obviously, most of them are structured very differently. Considering databases, XML files, other structured text files or Web Services as information supplier the complexness of integrating the information with their various describing models is not easy to handle.
Even companies that only want to setup a global information system (e.g. a Data Warehouse) are faced with integration problems. As a lot of departments were able to develop their own local information pools there can be a variety of different sometimes redundant data sources even inside a company.
In this paper an new approach of building such a global information
system is described. Besides the theoretical aspects it is mainly
shown that the system is really working and can easily be adapted
to the special needs, a certain Federated Information System has
to fulfill.

Each of these interfaces is usually presented in the form of an API, as a specification of the capabilities of the relevant component. However, while the predominant API model captures the behavior of individual interface members, it neglects the interactions among those members. We propose an approach that incorporates such interactions into an interface specification, and provide a practical application of the approach.

We argue that adaptation is necessary in a changing environment where static configuration of error control does not yield the best performance for many situations.

Grafikdaten in Netzwerken. In den letzten Jahren wurden verschiedene Konzepte für:
- Teleteaching,
- Teleseminare,
- OP-Übertragungen im medizinischen Bereich und
- Videokonferenzen
entwickelt und erfolgreich in die Praxis überführt.
Heute ist die FSU Jena eine der Universitäten, welche das Teleteaching-Konzept im regulären Studienbetrieb in Zusammenarbeit mit der TU Ilmenau und der BU Weimar einsetzt.
Bei den aufgeführten Systemen handelt es sich um synchrone Systeme mit getrenntem Grafikkanal. Da bei diesen Systemen eine hohe Qualität der Audio- Videoübertragung notwendig ist, werden die Daten in MPEG-2 encodiert dann im IP Netz übertragen.
Voraussetzung dafür ist aber die dazu notwendige Kapazität der Datenleitungen. Diese ist zwischen den Universitäten, bedingt durch das G-WiN, garantiert.
Viele universitäre Veranstaltungen haben aber andere Zielgruppen als bei einem Teleteaching Verbund. Internationale Kongresse und auch viele Lehrveranstal-tungen können und sollten einem breiten Nutzerkreis zugänglich gemacht werden. Dabei wird kein besonderer Wert auf eine bidirektionale Kommunikation gelegt(wie sie im synchronen Teleteaching-Systemenunabdingbar ist), sondern eine Verteilung an viele Interessenten mit unterschiedlichen Datenanschlüssen. Die Qualität sollte dabei dem Übertragungsmedium angepasst sein.

Traffic scheduling is considered as the key mechanism to support QoS with respect to protection of flows and fair allocation of the limited link bandwidth. However, scheduling schemes developed for wired networks can not be directly applied to wireless networks due to bursty and location-dependent channel errors. In this paper, we propose a scheduling scheme called Packetized Wireless Scheduler (PWS) for providing both fairness and protection. The key idea of PWS is to keep track of the channel state and to compensate the flows which have received less service due to poor quality of their wireless channel. Since our scheme uses a portion of the link bandwidth for giving an extra compensation service, our scheme can achieve fairness guarantees and protection to individual flows.

Furthermore, the UP encourages flexible adoption within its process framework, providing a structure that can scale up to projects involving hundreds of developers, or down to projects of just a few.
Contrary to some misperception, the UP encourages a light approach. Knowing and adopting the critical elements of the UP, avoiding some common misunderstandings, and reducing attention to its many optional elements, are keys to its successful_and agile _application. In this tutorial you will learn the essential and most useful UP concepts and practices, the keys to its successful introduction in an organization, and how to apply the UP in an adaptive and agile spirit.
Topics include:
_ The key UP ideas to know and apply.
_ The motivation and business case for the UP.
_ What UP artifacts are really worth creating?
_ UP anti-patterns: common worst-practices in adoption and use.
_ How to adopt the UP within an organization.

For example, many Extreme Programming (XP) practices and values are either part of the UP, or specializations of more general UP guidelines. What are these, and which may be adopted consistent with and within a UP project? Nevertheless, this tutorial motivates the need for more than pure XP on many projects, and promotes the skillful capacity of the UP to provide a variety of optional practices and artifacts on larger or higher-ceremony projects. You will learn why a combination of primarily the UP with some XP practices is an excellent process approach.
You will learn about the following:
_ XP practices within the UP.
_ Challenges of pure XP.
_ How to plan an iterative UP project.
_ Tips for good UP artifacts and models.

It can be
used to cleanly modularize the crosscutting structure of concerns such
as exception handling, multi-object protocols, synchronization,
performance optimizations, and resource sharing.
 
When implemented in a non-aspect-oriented fashion, the code for these
concerns typically becomes spread out across entire programs. AspectJ
controls such code-tangling and makes the underlying concerns more
apparent, making programs easier to develop and maintain.
 
This tutorial will introduce aspect-oriented programming and show how
to use AspectJ to implement crosscutting concerns in a concise,
modular way.  We will use examples to develop participant's
understanding of aspect-oriented programming through AspectJ. We will
also demonstrate and use AspectJ's integration with IDEs such as
Eclipse, JBuilder 6 and Forte4J, and emacs, in addition to the core
AspectJ tools.

ständig gestiegen. Viele Workshops, Diskussionsrunden, Veröffentlichungen
und Sonderhefte von Zeitschriften standen und stehen unter dem Titel.
Gleichzeitig ist das Gebiet sehr dynamisch und es gibt ständig zahlreiche Neu- und Weiterentwicklungen.
In diesem Tutorial wollen wir verschiedene Ansätze, Veröffentlichungen und
Implementierungen vorstellen, sie klassifizieren und einordnen. Einige
Schwerpunkte werden die Speicherung von XML-Dokumenten, Indizierungsverfahren,
Anfragesprachen für XML-Dokumente, sowie das Generieren von XML-Dokumenten
aus Datenbanken sein.
Ausgehend von einer Klassifikation von XML-Dokumenten wird ein allgemeines
Architekturmodell für XML-Anwendungen entwickelt.
Auf dieser Architektur aufbauend werden verschiedene Verfahren zur Speicherung
von XML-Dokumenten vorgestellt.
Die dabei eingesetzten Verfahren sind teilweise an Verfahren aus den Bereichen
Datenbanken und Dokumentenverarbeitung angelehnt.
Darüber hinaus haben sich auch neue Verfahren etabliert, die speziell auf XML-Anwendungen zugeschnitten sind.
In dem Tutorial wird eine Systematisierung der zahlreichen bekannten Ansätze zur Speicherung von XML-Dokumenten entwickelt.
Indexstrukturen für XML-Dokumente werden ebenfalls vorgestellt.
Eng mit der Speicherung von XML-Dokumenten verbunden, sind Anfragen an die gespeicherten Dokumente.
Ausgehend von generellen Anforderungen an Anfragesprachen werden die
Erfordernisse für spezielle XML-"Anfragesprachen dargelegt.
Mit XQuery wird ausführlich der absehbare Standard im Bereich Anfragesprachen vorgestellt.
Einige der vorgestellten Verfahren benötigen explizit angegebene
Schemainformationen zur Speicherung der XML-Dokumente.
Die konzeptuelle Modellierung von Schemata ist deshalb ein weiteres Thema des
Tutorials.
Die Speicherung von XML-Dokumenten ist nicht die einzige Verbindung der Gebiete XML und Datenbanken.
Viele XML-Dokumente sollen aus Daten generiert werden, die in Datenbanken
gespeichert sind, für diese Aufgabe stehen ebenfalls verschiedene Verfahren zur Verfügung.
Es gibt eine ganze Reihe von kommerziellen Systemen zur Verwaltung und zur Speicherung von XML-Dokumenten von XML-Datenbanken bis hin zu XML-Datentypen objekt-relationaler Datenbanken, diese werden im Detail vorgestellt.
Das Tutorial wird einen umfassenden Einblick in das sehr dynamische Gebiet

of agent development platforms that support building of agent
systems. This tutorial will enable participants to become familiar
with a design methodology for building such systems, that has been
developed as a result of industrial and pedagogical needs.

The methodology covers all stages of SW development - specification,
architectural design, detailed design, implementation, testing and
modification. This tutorial will focus primarily on the specification
and design stages.

The specification and architectural design phases are quite generic
and applicable to any kind of agent system. Focus is on goals and
scenarios, groupings of functionalities into agents, communication
protocols and overview of the system.

The approach to design is hierarchical allowing the designer to work
at arbitrarily many levels of abstraction, making the methodology
easily scalable for large systems.

The detailed design techniques are developed specifically for BDI
style systems such as JACK, PRS, JAM and dMars. In detail design we
look at design of the capabilities the individual agents require. At
this level we cover design of plans, events and data. We have
developed a graphical documentation style which allows the designer to
clearly organise the relationships between events, plans and data, and
to visualise how these work together to achieve the agent goals.

A common problem when new users start to use an agent development
environment is that the code they write does not really fit the agent
paradigm and does not make use of the power available in the system.
The design methodology taught in this tutorial will assist developers
to understand and think within the agent paradigm, thus obtaining
greater benefit from the agent development environments which they
use.

The tutorial will contain practical work where participants work through
examples of the different design stages. Due to time constraints some
stages will be covered in less detail than others.

fuer die Server-seitige Java-Entwicklung. Als Teil der
Java 2 Enterprise Edition (J2EE), haben EJBs das Ziel, die
Entwicklung wiederverwendbarer, plattformunabhaengiger
und verteilbarer Software-Komponenten zu ermoeglichen.
Sie stellen hierzu ein Framework bereit, das eine Basis fuer die
Entwicklung entsprechender Geschaeftskomponenten bzw. Anwendungen
darstellt. Elemente dieses Frameworks sind bspw. die EJB-Typen
Session-Beans und Entity-Beans, ein Namensdienst,
Mechanismen zur Verwaltung verteilter Transaktionen auf JDBC-Basis,
die Integration mit CORBA-basierten Systemen, um u.a. auch heterogene,
nicht Java-basierende Anwendungen ansprechen zu koennen, usw.
Ueber J2EE wiederum wird die Integration mit Web-Servern, z.B.
via Servlets, angeboten.

Die Ablaufumgebung fuer EJB-basierende Komponenten sind typischerweise sogenannte Applikationsserver. Produktbeispiele sind u.a. Orbix E2A Application Server Platform (IONA),
Borland Enterprise Application Server oder WebSphere (IBM). Aufgabe der Applikationsserver ist insbesondere Qualitaetsmerkmale fuer den Ablauf von EJB-Anwendungen sicherzustellen, wie Skalierbarkeit und Lastbalancierung auch bei grossen Nutzerzahlen, moeglichst dynamische
Konfigurierbarkeit bspw. fuer Online-Anwendungen u.a.m.

Auf Basis derartiger Applikationsserver sind bereits eine Reihe
von Anwendungen im produktiven Einsatz. Hier wiederum ist der Uebergang von
"einfachen" JSP/Servlet-basierten Anwendungen hin zu Anwendungen, die
viele J2EE-Elemente (EJB, JCA, JMS, RMI-IIOP CORBA-Interoperabilitaet)
nutzen zu beobachten. In Produktion sind derzeit vor allem EJB 1.1-Standard
basierte Systeme, wobei viele Anwendungen die aktuelle EJB 2.0-Standard
beginnen einzusetzen, denn EJB als Technologie wird kontinuierlich weiterentwickelt.

Ziel des Tutorials ist es, eine Einfuehrung in die genannten
Merkmale der EJB-Technologie im Rahmen von J2EE zu geben.
Es gliedert sich in folgende Themenbloecke:
- EJB im Rahmen von J2EE - Ueberblick
- EJB-Konzepte
- Ueberblick Namensdienst (JNDI) und DB-Zugriffe (JDBC)
- Stateful und Stateless Session Beans
- Container und Bean-managed persistence Entity Beans
mit EJB 1.1 und EJB 2.0 container-managed-relationships
- EJB "Message Driven Beans" & Java Messaging Service (JMS)
- EJB-Transaktionen
- EJB-Sicherheit inkl. CSIV2L0-basierter "secure interoperability"
- Java Connector Architecture (JCA)
- kurzer Ausblick: Geplante Neuerungen in J2EE 1.4
- Beispiele
- J2EE-Produktbeispiel: IONA Orbix E2A J2EE Application Server auf Basis von CORBA
- J2EE-Architektur- und Einsatzbeispiele aus Projekten von JSP/Servlet-Anwendungen,

Ein aktueller Ansatz für eine objektorientierte Generatortechnik basiert auf den Frame/Slot-Konzepten, die ursprünglich aus dem KI-Bereich kommend, jetzt u.a. angewandt werden in Werkzeugen wie Netron Fusion (Paul Basset). In Deutschland entwickelt wurde ANGIE als die neueste und umfassendste Implementierung dieses Prinzips.
Anhand von praxisorientierten Beispielen wird die Anwendung dieser Konzepte dargestellt. Kleine, überschaubare Generatoren, mit denen Design-Pattern wahlweise in C++, Java oder C# übersetzt werden, dienen dazu die Grundlagen zu erläutern. Weitergehende Beispiele zeigen wie Systemfamilien implementiert werden können, wobei insbesondere der Austausch von Meta-Daten im XML-Format mit anderen Werkzeugen eine Rolle spielt. Ein Ausblick in die weitere Entwicklung der Konzepte und Werkzeuge rundet die Darstellung ab.

Während die Geschäftsprozessoptimierung von der Betriebswirtschaft voran getrieben wird, ist es die Informatik, die die Mittel zur Modellierung und damit zur Analyse solcher Prozesse bereitstellt. Ein Ziel ist hier u. a. die Schaffung unternehmensweiter Datenmodelle, die die Entwicklung und Integration von Informationssystemen fördern.
Methoden und Verfahren zur Modellierung von Geschäftsprozessen gibt es genug. Jedoch ist weder eine einheitliche Darstellungspräsentation im Sinne eines Standards verfügbar, noch eine strukturierte Vorgehensweise. Die Unified Modeling Language (UML) entwickelt sich hier zur Basis- bzw. Standardnotation. Im Folgenden soll eine mögliche Herangehensweise zur objektorientierten Geschäftsprozessmodellierung auf Grundlage der UML Version 1.3 aufgezeigt werden.
Die oben vorgestellte Herangehensweise eignet sich zur
Geschäftsprozessmodellierung insbesondere im Bereich der Geschäftsprozessoptimierung, da die Konzentration dabei den Kernprozessen gilt. Kernprozesse betreffen diejenigen Aktivitäten, die Marktstellung und Wettbewerbssituation eines Unternehmens bestimmen.
Die Konstrukte der UML bieten eine für die Geschäftsprozessmodellierung adäquate Möglichkeit, die entsprechenden Strukturen zu modellieren. Hinsichtlich des Vorgehens bei der Beschreibung solcher Prozesse basierend auf einer objektorientierten Sichtweise ist bisher jedoch kein allgemein anerkannter Ansatz verfügbar. Der hier aufgezeigte Weg soll helfen, die Lücke zwischen der reinen Darstellungsform und ihrer Anwendung im Bereich der Unternehmensmodellierung zu schliessen.
Im Bereich der Präsentation von Use Cases wurden Erweiterungen hinsichtlich des zeitlichen Ablaufs von Geschäftsprozessen aufgezeigt. Vorteilhaft wirkt sich hier die Anwendung der Verantwortungsbereiche (Swimlanes) aus. Dies erlaubt eine direkte Zuordnung von Geschäftsprozessen zu ihren operativen Einheiten innerhalb eines Unternehmens. Durch Einbeziehung von Aktivitätsdiagrammen und ihrer Unterteilung in Arbeitsprozesse und Funktionsprozesse können die anfangs modellierten groben Strukturen herunter gebrochen werden.
Ein Geschäftsklassendiagramm präsentiert die für die Abarbeitung der Geschäftsprozesse relevanten Objekte und ihre Beziehungen untereinander.

an overall, well-integrated approach to develop software product families
they can use in practice. The key of our process resides in its ability to
define the software family's potential economies of scope at the
requirements level and, as strictly as possible, propagate these economies
to the reference architecture (the platform). The platform is the most
critical asset of a product family. Its scope both determines its ability to
handle the variation among the different product family members but also
really how much return on the overall investment can be made by switching
the organization to a product family engineering mode of operation. Hence,
gaining a quantitative understanding of the tradeoffs involved when
including or excluding products or features within the family and/or
platform is critical to the success of any product family engineering
endeavor.

To quantify a family economies of scope we use the goal-question-metric
approach integrated within a product map structure as the basis to value and
prioritize features. A requirements engineering process then elicits
full-bodied software requirements segmented as commonalities and
variabilities. The latter, quantified using parameters of variations, serve
as the basis for the decision model -- the PL discriminator. Next, these
requirements are mapped to task and quality scenarios, which are then used
to construct the platform architecture (object-oriented frameworks).
Enterprise organization transition stages are planned and described using
our platform-driven user-to-engineering model. The definition, propagation
and maintenance of the economies of scope over time is fundamental to the
engineering success of a product family. The platform must be
"right-designed' to the specification of the trade-offs defined and/or
accepted during the family definition to provide the anticipated benefits.

How do we stop ourselves from
forgetting the lessons of previous paradigms and just hacking our way
through?
The web's core mechanisms lend themselves all too easily to cut-and-paste
re-use, ad-hoc scripts, direct-to-database code, and fragmented business
logic. In the name of time-to-market, too many of us abandon what we know
and take the path of least resistance. There are capable and articulate people
telling us this is exactly what we should be doing.
We believe, that the lessons of objects do apply to the web. If we apply
them wisely we can have good time-to-market for version 1.0, ship version 2.0
successfully, and improve the user experience along the way. But it's not
obvious how to apply these lessons. What, if anything, is MVC for the web?
What are the architectural layers? How do we support multiple channels
within these layers, when presentation differences can easily creep into the
domain logic? What about EJB?

This tutorial surveys current web technologies with an emphasis on OO
usage, provides best practices and examples from Java and Smalltalk, discusses
myths and truths about components, and describes architecture and development
practices that support good practices.

They come in different flavours, most prominently CORBA, DCOM, .NET Remoting and, most recently, XML webservices.
While each of these technologies use different APIs, protocols or implementation techniques, they are all based on the same patterns. From a high-level view, they all implement the Broker pattern described in the POSA1 book. However, a closer view on the subject reveals several finer grained patterns around the areas of quality of services, remoting framework design, asynchronous invocations, and more.
This tutorial presents a collection of about 40 patterns describing how these oo remoting middlewares work. It also provides real-life examples using CORBA, .NET remoting and webservices.
The tutorial will introduce the patterns one by one, and illustrate them using examples from the mentioned technologies. This provides a step-by-step introduction to the internals of the full-fledged remoting frameworks in use today.

Research activities as well as industrial developments focus on implementing the mechanisms required for remote invocation and automation of Web Services (using standards such as UDDI, WSDL, X-lang, WSFL, e-speak, .NET etc). Concurrently, the idea and vision of the Semantic Web is catching on and researchers as well as companies have started to realize the benefits of this great vision, which includes ontologies that allow machine-supported data interpretation.

While both efforts are very powerful in themselves, their combination, termed Semantic Web enabled Web Services (SWWS) opens tremendous possibilities. Web services will transform the web from a static collection of information into a distributed device of computation. Semantic Web technology makes the World Wide Web machine-interpretable. Semantic Web enabled Web Services, such as the DAML-S effort, will allow the automatic Discovery, selection and execution of inter-organization business logic making areas like dynamic supply chain composition a reality.

This tutorial brings together theories, challenges, issues, languages and tools from the Semantic Web, Web Services and Agent Technology. We will present the current state of the art in Web-Based Services and sort through the increasing array of relevant tools, languages and theories both from academia and industry. The tutorial includes an exploration of the following:

* Current state of the art in web service research and industrial
standards.
* Vision and implications of the Semantic Web and Web Service symbiosis.

* Exploration of the current work and approaches to SWWS

helps you grow your software in small increments.
As a developer, you will write automated code-level unit tests that help you
build the software right. As a tester, you will supply automated system-level
acceptance tests that help the developers build the right software.
Working this way has a number of benefits, among them being able to change
any code in the system with confidence, therefore tremendously reducing your
programming stress.
This tutorial will have short introductory talks, but primarily it will teach
you first-hand experience with required development techniques, such as unit
testing, test-driven development, refactoring, acceptance testing, and isolation
testing with mock objects. In a couple of hands-on exercises, you will learn how
to write automated tests using the JUnit testing framework.

JXTA is an open
source project which was started by Sun Microsystem's technology expert Bill
Joy and which is still pushed by Sun intensively. In contrast to classical
open source projects, JXTA is not primarily focused on software. It stands
for the specification and architecture of a Peer-to-peer platform where the
ingredients, the protocols, and their interaction are specified. Main goal
is the develop of several open protocols that allow networked devices, from
mobile phone over PDA to desktop PC, to communicate with each other and
exchange information as peers in a P2P network. This design is abstract and
programming language independent. Simultaneously with the concepts, however,
a reference implementation as a proof of concept is developed in Java. This
tutorial describes the background of peer-to-peer computing, the concepts
and protocols of JXTA and teaches the participants how to write their own
JXTA applications.

•Einleitung und Motivation
•Einführendes Beispiel
•Struts Details
•Beispiel und Realisierung
•Bewertung
•Zusammenfassung

2.Inhalt
Das Tutorial zeigt an ausgewählten Beispielen, die Erstellung von einfachen Web-Anwendungen unter Verwendung des JSP Frameworks Struts und weiterer Tools.
Struts ist ein Framework der Open Source Projekte der Apache Foundation.
Das Framework unterstützt und vereinfacht die Entwicklung des Controllers und der View. Die Entwicklung der Business-Logik wird von Struts nicht beeinflusst.

Der Tradition von Kernighan & Ritchie folgend, beginnt der praktische Teil mit dem „Hello World„ Beispiel.
Im weiteren Ablauf des Tutorials werden folgende Punkte im Struts Kontext behandelt:
•Grundlagen
•MVC (Model View Controller)
•Designpattern
•JSPs, JavaBeans und Taglibs
•Integration mit EJB

•Nutzung von JNDI und JDBC
•Konfiguration
•Erweiterungen für eigene Anwendungen
•Interne Architektur

Nach der Einführung wird an Hand realer Beispiele der Einsatz von Struts demonstriert. Dazu werden Lösungen unter anderem für folgende Geschäftsanforderungen entwickelt:
•Bereitstellung von Content
•Abrechnung
•Personalisierung
Hierfür werden JSPs, Taglibs (eigene als auch Struts Taglibs) und JavaBeans für die Präsentationsschicht verwendet. Die Web-Anwendung wird durch die Anbindung des Business und Resource-Tiers mit JNDI und JDBC vervollständigt.
Zum Abschluss wird der Einsatz von Struts unter den technischen Kriterien (Sicherheit, Wartbarkeit, Erweiterbarkeit und Architektur), den Nutzungskriterien (Einarbeitung, Einfachheit) und den Qualitätskriterien (Robustheit, Performance) bewertet.

3.Einordnung
•Level : Intermediate, grundlegende Kenntnisse der Anwendung von JavaServer Pages und Servlets werden erwartet
•Zielgruppe : Designer , IT Berater , technische Projektleiter , Java Developer
•Sprache: deutsch

Die mit der generischen Metasprache XML definierten Vokabulare und Sprachen finden Einsatz vom Datenaustausch bis hin als native
Applikationsdatenspeicherungsform.
Ausgehend vom Primärstandard des World Wide Web Consortium (W3C) entwickelt sich derzeit ein dynamisches Geflecht ineinander verzahnter und aufeinander aufbauender Standards.
Den, gemessen an seiner Wirkungsmacht, wichtigsten Standard dürfte "XML Schema" darstellen, der zu Grundlage der XML-Sprachen der zweiten Generation wurde.
Ausgehend von dieser XML-Sprache zur Definition eigener XML-Sprachen stehen wir derzeit einer Entwicklung des Internets in eine neue Anwendungsform gegenüber. Nach den ausschließlich textbasierten Anwendungen der Frühzeit (etwa: Telnet, FTP, Gopher, ...), dem darauf folgenden Übergang zur Übertragung zum präsentationsorientierten Datentransfer durch die Entwicklung des World Wide Web bewegen wir uns heute hin zu einer zunehmend interaktiven pervasiven und in
letzter Konsequenz nicht mehr sichtbaren Applikationform deren erste Anzeichen heute in den Frühformen dienstorientierter Angebote zu sehen sind.
