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.

We selected, for these post-workshop proceedings, 14 papers, amongst 29 submitted, two tutorials, and one keynote talk. FIDJI2003aimedatpromotingascienti?capproachtosoftwareengineering. 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 - managementofevolutions/iterationsintheanalysis, 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 The organization of such a workshop represents an important amount of work.
