I don't think we have any support at the moment foe EJB, Hibernate and 
Struts. I know of a project in ISIS where they have models for CORBA and 
CCM (Corba Component model). 

I don't know exactly what your goals are but I can talk a little about a 
simple use case of GReAT in your setting. I might completely of target but 
at least it will get the discussion going.

you would probably want to first create modeling environments for the 
different target environments e.g. EJB, Hibernate, Struts. The environment 
can then have their code generators that generate code/documentation/XMI. 
In MDA terms this would be the PSM modeler. We could add these models to 
the GME contribution library for future users. 

Then you would create a PIM modeler which is your front end. GReAT could 
then be used to convert the PIM models to whichever PSM you want. 

In the process described you will unfortunately have to implement all the 
parts as none of these environment exist. The good news is that using GME 
creating modeling environments is easy.

GReAT and UDM do not currently have an "export to XMI" for the instance 
models of UDM. UDM class diagrams can be converted to XMI but they do not 
buy much. If you are an expert in XMI a generic export to XMI for UDM 
models would be really helpful and highly appreciated. :)

Thanks,
Adi
