[Solved:] How to "Generate Java Code"? [message #1219800]

I just discovered the menu option (right click on Class in Class Diagram)
=>Java=>"Generate Java Code"

It gives me following error message:
...................................................
"Problem Occured"
'Generate java classes' has encountered a problem.
No classes or packages produced from the
transformation. Nothing is generated.
...................................................

How do I correctly use this feature to generate java code from an Papyrus UML class diagram? Are there some Tutorials on java code generation with Papyrus?

I only know about some old topics on java code generation:
http://stackoverflow.com/questions/7130937/how-to-generate-code-by-papyrus-on-eclipse
http://www.eclipse.org/forums/index.php/mv/msg/466701/1067046/#msg_1067046

The impression that I get from those old topics is that Papyrus is not able to generate java code on its own and that I would have to use additional plugins. Did this change? If Papyrus is not yet able to generate java code: what is the meaning of that context menu?

Hi Stefan,

I have just try the java generator, and I have the same problem. A
library is missing in qvto.
This is a new bug. I will correct it asap.
Can you fill a bug report in bugzilla (with me in cc) ?

Otherwise, this generator work as you have tried:
- select a class or a package, and choose "generate java file". The
class will be generated.
- you can also model projects, src dir and packages in your UML model
(by using stereotypes). The generator will generate the classes in the
specified project, sources dir and packages.

Hope this help,
Cedric

Try the UML to Java generator based on Acceleo : https://github.com/ObeoNetwork/UML-Java-Generation
