Hello,

I would appreciate if you can answer me :

I have defined a class diagram with papyrus with the goal to automatically generate the Java corresponding code, for the structure it seems good and I find no problem, but i want that the objects interaction will be automatically generated from sequence diagrams, and the operations code of any class will be also generated from activity diagrams.

Is Papyrus offers this functionality?

With Best Regards.

Hi,

Papyrus SW designer does not offer Java code generation for behavior diagrams. It offers C++ code generation for state-machines diagrams and will soon offer it for Java as well. However, it does not offer code generation from sequence diagrams.

Thank you very much for your answer, then if you have any idea to generate the java code from these diagrams can i get the EMF corresponding meta-model and the Ecore model to define an ATL transformation?

Hi,

well, a UML model is an EMF model (there is an UML.ecore in the org.eclipse.uml2.uml model). So, I don't see a problem to write ATL transformations, but you would have to rewrite a Java generator from scratch. Therefore, I would recommend to look into the transformation approach in Papyrus SW designer. The idea is that the code generators support the basic structural UML entities and opaque expressions. Additional functionality, such as state-machine generation is provided by model 2 model transformations (i.e. UML to UML) that are part of a configurable/extensible transformation chain. Doing so, the existing Java code generator is reused. In this case, the required transformation would not be very different from the one we have for C++ .

Hope that helps
