It's not a problem and that's a perfectly valid assumption.  I make sure 
to monitor questions in the newcomers newsgroup, but I do always suggest 
they start using the EMF newsgroup instead...

Generally if the *.genmodel exists, you'd invoke "Reload..." to make it 
import from whatever model source it was created from in the first 
place.  It's possible to create (import) a model from an existing Ecore 
in the file system say, from annotated Java (Java interfaces with @model 
information in the Javadoc), an XML Schema, or a Rose model.  I'm not 
sure actually what question you're asking.  :-P

Yes, you only need to create a dependency on it and then you'll be able 
to reuse all the classes.

That would seem bad.  The project with the *.genmodel/*.ecore is what's 
generated from the model and it sound like you just want to reuse that 
generated stuff.  So it's just a matter of creating your project and 
adding a dependency (typically done by working with the MANIFEST.MF).
