Hi,

I created a “superb” Class-diagramm within MyEclipse For Spring (latest version, 30-days Trial-version) , and now I wanted to let generate the java code.
When I choose the “Generate java code…” option, nothing happens !?!??!

I’m using MacOSX 10.6.

Thank you very much.

Esteban.

Esteban,
Can you give some more information on this?
1. Can you copy paste your installation details from MyEclipse > Installation Summary > Installation Details?
2. Can you look for any relevant errors logged in workspace dir > .metadata > .log?

Thanks, Shalini for your answer.

What I see in the .log file is the following Exception:
Is there something (plug-in !?) missing ?

Esteban,
Can you try using the -clean as mentioned in the link below –
https://www.genuitec.com/forums/topic/troubleshoot-using-the-clean-command-line-argument/
Also, Can you switch to a new workspace and check if the issue persists?

[echavez]

Shalini,

I restarted eclipse (-clean) but same result. But after switching to a new workspace, the code generation dialog appeared (- the one where I choose the classes to generate). This didn’t appear before. Seems that its going on…
Now the question : how can I export my diagram from the previous workspace into the new one. I don’t would like to create anything again from scratch…

Thanks,
Esteban.

[support-shalini]

Esteban,
I am afraid you cannot export the diagram from the IDE. However, you can copy the .uml and .umldi files into your new workspace project.
