Thanks for your offer Tom. I will come back to it when I start working on  
the app again.
btw: Will EclipseLink offer dynamic adding/removing of Entities to the  
EntityManager during runtime?
In OSGi I would like to add and remove new Entities to the running system,  
without restarting the app.
Dynamic-JPA allows that to a certain degree. With Hibernate I wrote myself  
a little helper that recreated the EM each time the bundle configuration  
changed. But I was under the impression JPA would already do that, which  
it does not, to my surprise.
