Web applications running inside a webbrowser bring new requirements to the traditional desktop application devel- opment process. Since web applications usually don’t come to life using model based approaches or Story Driven Mod- elling the Fujaba Toolsuite has to be adopted to fulfil the new requirements. The Fujaba group of Kassel wanted to get all the help we are used to get from Fujaba in ordinary application develop- ment for our web applications, too. Thus, we are developing a new code generation for the generation of Google Web Toolkit compliant Java code that will then be compiled into JavaScript running on web browsers. In addition, we develop tool support for building the GUIs of such web applications. And, on the server side, we develop technologies to facilitate service development with Fujaba. This paper reports on the design of these new Fujaba web components.Sat Mar 29 22:38:08 CET 2008GermanyTechnical ReportFebruary{Systematic Story Driven Modeling}2004flipbook DA fup fujaba sdm Sat Mar 29 22:34:06 CET 2008February{Isolating Relevant Component Interactions with JINSI}2006flipbook askigor DA jinsi When a component in a large system fails, developers encounter two problems: (1) reproducing the failure, and (2) investigating the causes of such a failure. Our JINSI tool lets developers capture and replay the interactions between a component and its environment, thus allowing for reproducing the failure at will. In addition, JINSI uses delta debugging to automatically isolate the subset of the in- teractions that is relevant for the failure. In a first study, JINSI has successfully isolated the relevant interaction of a JAVA component: “Out of the 32 interactions with the VendingMachine compo- nent, seven interactions suffice to produce the failure.”Sat Mar 29 22:26:01 CET 2008SIGSOFT FSE1-10Isolating cause-effect chains from computer programs.2002delta debugger DA ask igor Sat Mar 29 20:21:21 CET 2008CoRRinformal publicationDebugging Backwards in Timecs.SE/03100162003omniscient debugger java DA ODB Sat Mar 29 20:11:09 CET 2008OOPSLAconf/oopsla/2007535-552Scalable omniscient debugging.2007omniscient TOD trace debugger DA Sat Mar 29 17:27:20 CET 2008The Addison-Wesley Signature SeriesTest-Driven Development by Example2003testing DA junit tdd Sat Mar 29 16:52:54 CET 2008Modellgetriebene Softwareentwicklung: Techniken, Engineering, Management2007driven mdd modell DA Sat Mar 29 16:07:26 CET 2008Braunschweig, GermanyDiploma Thesis{Automatische JUnit Testgenerierung aus UML-Szenarien mit Fujaba}2004automated scenario testing DA junit fup fujaba uml Sat Mar 29 15:27:35 CET 2008Braunschweig, GermanyBachelor Thesis (Studienarbeit){Design Level Debugging mit Fujaba}2002edobs flipbook level dobs DA debugging design Sat Mar 29 15:26:46 CET 2008Bad Schussenried, Germany{Informatiktage 2002 der Gesellschaft für Informatik (GI)}November{Design Level Debugging mit Fujaba}2002edobs flipbook level dobs DA debugging design 8 - 9Sat Mar 29 14:54:30 CET 2008Natal, Brasil{3rd International Workshop on Graph-Based Tools (GraBaTs) ICGT Workshop}September{eDOBS - Graphical Debugging for Eclipse}2006edobs flipbook DA fujaba 17 - 23Fri Mar 28 15:33:45 CET 2008CoObRA: Eine Plattform zur Verteilung und Replikation komplexer Objektstrukturen mit optimistischen Sperrkonzepten2007phd flipbook coobra DA se fujaba scm n der vorliegenden Arbeit wird die Konzeption und Realisierung der Persistenz-, Verteilungs- und Versionierungsbibliothek CoObRA 2 vorgestellt. Es werden zunächst die Anforderungen an ein solches Rahmenwerk aufgenommen und vorhandene Technologien für dieses Anwendungsgebiet vorgestellt. Das in der neuen Bibliothek eingesetzte Verfahren setzt Änderungsprotokolle beziehungsweise -listen ein, um Persistenzdaten für Dokumente und Versionen zu definieren. Dieses Konzept wird dabei durch eine Abbildung auf Kontrukte aus der Graphentheorie gestützt, um die Semantik von Modell, Änderungen und deren Anwendung zu definieren. Bei der Umsetzung werden insbesondere das Design der Bibliothek und die Entscheidungen, die zu der gewählten Softwarearchitektur führten, eingehend erläutert. Dies ist zentraler Aspekt der Arbeit, da die Flexibilität des Rahmenwerks eine wichtige Anforderung darstellt. Abschließend werden die Einsatzmöglichkeiten an konkreten Beispielanwendungen erläutert und bereits gemachte Erfahrungen beim Einsatz in CASE-Tools, Forschungsanwendungen und Echtzeit-Simulationsumgebungen präsentiert. --------------------------------------------------------------------------------------------------------------------------------------- This thesis presents the conception and realization of the persistency, distribution and versioning library CoObRA 2. Foremost the requirements for such a framework are analyzed and defined. Subsequently existing technologies from the application area and related work are introduced. Afterward the approach used in the library is presented. It utilizes change protocols to define persistent data and versions of documents. This concept is based on a mapping to constructs from graph theory, to define the semantics of models, changes and their application. The desciption of the realization focuses on the design of the library and the decisions which were leading to the software architecture, afterwards. This is a central aspect of the presented work, as the flexibility of the framework was an important requirement. The thesis concludes with presenting several example applications, including the experiences gained while using the library in CASE tools, research programs and real time simulation software.Fri Mar 28 15:18:01 CET 2008Germany{Technical Report tr-ri-99-211}{Story Driven Modeling}1999wrongurl fujaba nopdf sdm Fri Mar 28 15:02:09 CET 2008Kassel, Germany{Graph Transformation Tools Contest on 3rd International Workshop and Symposium on Applications of Graph Transformation with Industrial Relevance (AGTIVE 2007)}October{Implementing Ludo with Fujaba - a Case Study}2007edobs flipbook ludo wrongurl DA nopdf 10-12Fri Mar 28 14:55:33 CET 2008ACEconf/ace/2004125-129CRPITVisualising Java Data Structures as Graphs.302004edobs flipbook DA ljv We present a simple, general-purpose tool for visu- alising Java data structures. The tool uses Java re- flection and an open-source graph drawing program to produce text-book quality depictions of arbitrary Java objects. The tool offers certain pedagogical advantages over other “heavy-weight” visualisation systems. Its sim- plicity and generality means that students are able to visualise their own data structures, rather than passively observing a limited range of “correct” visu- alisations prepared in advance by the lecturer. The tool supports an active, exploratory style of learning, and is ideally suited for use in CS1-level courses that introduce Java references and arrays, as well as a range of CS2-level data structure material. Initial classroom results are encouraging. Fri Mar 28 14:49:15 CET 2008Electr. Notes Theor. Comput.

Rößling, V. Almstrum, W. Dann, R. Fleischer, C. Hundhausen, A. Korhonen, L. Malmi, M. McNally, S. Rodger and J. A. Velázquez-Iturbide, Exploring the role of visualization and engagement in computer science education, ACM SIGCSE Bulletin 35 (2003), pp. 131–152], which set the stage for the work described here. That work has resulted in the newest release of a system called JHAVÉ, which fosters active engagement on the part of learners by providing a set of standard support tools for certain types of Algorithm Visualization (AV) systems. These AV engines must implement the JHAVÉ Visualizer interface. In return, such engines have convenient access to the engagement-based tools offered by JHAVÉ. The details of adapting one such engine, Animal, are also described. Fri Mar 28 14:44:55 CET 2008IEEE Computer Graphics and Applications549-55JHAVÉ: Supporting Algorithm Visualization.252005edobs visualization jhave flipbook DA algorithms Algorithm visualization (AV) uses computer graphics to depict an algorithm's actions. For computer science students, AV holds the promise of helping them understand algorithms more easily and in greater depth. However, after 15 years of intensive research in this area, that promise remains largely unfulfilled. This article argues that we now have a better understanding of what must be done to turn AV from being merely impressive graphics into an effective pedagogical tool for computer science educators. The article provides an overview of what has been learned from past effectiveness studies. This knowledge is then related to an engagement taxonomy defined in a recent working group report on AV effectiveness. The article then describes the JHAVÉ system, which fosters this type of active engagement by providing a set of standard support tools for certain types of AV systems.Fri Mar 28 14:00:53 CET 2008SIGPLAN Notices122-27{DDD} - A Free Graphical Front-End for {UNIX} Debuggers311996gdb edobs flipbook ddd DA diagram The Data Display Debugger (DDD) is a novel graphical user interface to GDB and DBX, the popular UNIX debug- gers. Besides “usual” features such as viewing source texts and breakpoints, DDD provides a graphical data dis- play, where data structures are displayed as graphs. A sim- ple mouse click dereferences pointers or reveals structure contents. Complex data structures can be explored incre- mentally and interactively, using automatic layout if pre- ferred. Each time the program stops, the data display re- flects the current variable values. DDD has been designed to compete with well-known commercial debuggers; how- ever, it is free software, protected by the GNU general pub- lic license. In this paper, we give a quick presentation of DDD and describe its architecture and basic functionality from a technical point of view.Fri Mar 28 12:14:23 CET 2008Proceedings of SIGCSE 2007Dynamic Object Viewers for Data Structures2007edobs flipbook jgrasp java DA The jGRASP lightweight IDE has been extended to provide object viewers that automatically generate dynamic, state-based visualizations of data structures in Java. These viewers provide multiple synchronized visualizations of data structures as the user steps through the source code in either debug or workbench mode. This tight integration in a lightweight IDE provides a unique and promising environment for learning data structures. Initial classroom use has demonstrated the object viewers’ potential as an aid to students who are learning to write and modify classes representing data structures. Recently completed controlled experiments with CS2 students indicate that these viewers can have a significant positive impact on student performance.
