When I run the app nothing is in the database. It is completely empty!

I use OpenJPA as persistence provider. But as I mentioned earlier.
This issue has nothing to do with any persistence impl. I commented
out any persist/merge etc. methods so nothing on JPA is invoked.
The thing is serialization between a standalone app client and a
session bean instance (remotely called) does not work. The error
occures while marshalling or unmarshalling the data sent to the
session bean. On the server side no actual business method is
invoked. Thus nothing to with JPA...
Anyway thanks for your ideas.
