FIDJI 2003 was an international forum for researchers and practitioners in- rested in the advances in, and applications of, software engineering for distri- ted applicationdevelopment. Concerningthe technologies,the workshopfocused on “Java-related” technologies. It was an opportunity to present and observe the latest research, results, and ideas in these areas. All papers submitted to this workshop were reviewed by at least two members of the International Program Committee. Acceptance was based primarily on originality and contribution. We selected, for these post-workshop proceedings, 14 papers, amongst 29 submitted, two tutorials, and one keynote talk. FIDJI 2003 aimed at promoting a scientific approach to software engineering. The scope of the workshop included the following topics: – design of distributed Java applications – Java-related technologies – software and system architecture engineering and development methodo- gies – development methodologies for UML – development methodologies for reliable distributed systems – component-based development methodologies – management of evolutions/iterations in the analysis, design, implementation, and test phases – dependability support during system life-cycles – managing inconsistencies during application development – atomicity and exception handling in system development – software architectures, frameworks, and design patterns for developing d- tributed systems – integration of formal techniques in the development process – formal analysis and grounding of modeling notation and techniques (e. g. , UML, metamodeling) – supporting the security requirements of distributed applications in the - velopment process – refactoring methods – industrial and academic case studies – development and analysis tools Theorganization of such a workshop represents an important amount of work.
