I tried the latest EclipseLink version with our jpa-eclipselink

fine there, so we can rule that out:

Hey Jim,
Wonder if this might be your situation too:
http://www.nabble.com/rg.apache.openejb.OpenEJBException%3A-Unable-to-determine-the-module-type-of-tp24921373p25013439.html
See my followup and mod the "EMFProvider" class you have and have it
do the getResources() check I mention there.
That may help us narrow down your issue.
On a side note, that EMFProvider would make one great Singleton bean:
import javax.ejb.Lock;
import static javax.ejb.LockType.READ;
import javax.ejb.Singleton;
import javax.persistence.EntityManager;
import javax.persistence.EntityManagerFactory;
import javax.persistence.PersistenceUnit;
@Singleton
@Lock(READ)
public class EMFProvider {
@PersistenceUnit(unitName = "daosample")
private EntityManagerFactory emf;
public EntityManager getEM() {
return getEMFactory().createEntityManager();
}
public EntityManagerFactory getEMFactory() {
return emf;
}
}
The result is an bean which is scoped at the app level just as if it
was a static. It's more thread safe -- the previous getEMFactory()
code could result in many EntityManagerFactory instances being
created. You also no longer need to actively clean up the
EntityManagerFactory as the container will do that for you.
That said, I'd get the classloading issues sorted out before
proceeding -- if things don't work now with the java se
"Persistence.createEntityManagerFactory" approach, they won't work
when OpenEJB attempts to make the same call.
