  Thank you Shaun, I have tried.  With this approach I also have the same
problem.  I'm not sure if the problem is that my oracle jdbc drivers are not
used as osgi bundles but as direct jar libraries. 

Caused by: javax.persistence.PersistenceException: Exception
[EclipseLink-28022] (Eclipse Persistence Services - 2.3.0.v20110604-r9504):
org.eclipse.persistence.exceptions.EntityManagerSetupException
Exception Description: Value [true] for the property [eclipselink.weaving]
is incorrect when global instrumentation is null, value should either be
null, false, or static.

  Do you think I should use the Gemini JPA ? I'm not sure what happens if I
use the Oracle jdbc drivers as library. 

  Thanks,
      Liviu
