The FUJABA environment

Fujaba is an acronym for From UML to Java And Back Again. The Fujaba environment aims to provide round-trip engineering support for UML and Java. The main distinction to other UML tools is its tight integration of UML class and UML behavior diagrams to a visual programming language. Our use of UML allows to model operations on graph-like object structures on a high-level of abstraction and leverages the user from programming with plain references at code level. Code generation from class diagrams is widely known and supported by most modern CASE tools. However, code generation from class diagrams creates class frames and method declarations without bodies, only. The actual work remains unsupported. The paper considers how Fujaba generates code from collaboration diagrams. It presents an example session
