class diagram from java via modisco [message #649902]

Is there a way of creating a class diagram in papyrus from a uml model that was created from java source by modisco.

I'm using the modelling-helios-SR1-incubation build downloaded yesterday from eclipse.org with papyrus and modisco installed via the Help -> Install modelling components menu item.

I find that if I try to open the modisco generated uml file in the papyrus editor then I get an error telling me it needs an associated .di and .notation file. I can't see an alternative method.

Hi Matt,

i don't have the exact answer to this, but i suggest you to have a look into the thread "Diagram generation from models" from october 2010 in the same newsgroup.

Hi,

You can't open directly a UML model with Papyrus.
But you can create a new Model from an existing UML model. It is the
way you should do.

Otherwise, if you want to reverse java code into existing Papyrus UML
models, you can use the java reverse plugins located in SVN
(org.eclipse.mdt.papyrus/trunk/extraplugins/java/):

- org.eclipse.papyrus.java.reverse
- org.eclipse.papyrus.java.reverse.ui

With this plugin, you can select one or more classes (or packages) in
the Package Explorer, and reverse them to the currently open editor with
one single click ! Of course, you can do it as often as you need it.

Hope this help,
Cedric

Thanks guys,

Fabian - I hadnt seen that thread ( http://www.eclipse.org/forums/index.php?t=tree&th=198258) - it suggests that I ought to be able to create a papyrus model from an existing uml model. The technique sketched by Gilbert in the thread hasnt worked for me but it looks like it should - the wizard generates the required files but seems to fail silently (clicking finish doesnt close it) and the files generated have missing elements. But there are other problems in the java -> papyrus pipeline (non empty kdm.log and non validating uml model) so I'm not clear where the root problem(s) actually lie.

Cedric - I'm not sure how to proceed as you suggest. It sounds like a lot of trouble to download and compile the classes from svn making sure all the dependencies work. Is it straightforward?
