How to prevent "Local transaction already has 1 non-XA Resource" exception?
- by Zeratul
Hi,
I'm using 2 PU in stateless EJB and each of them is invoked on one method:
@PersistenceContext(unitName="PU")
private EntityManager em;
@PersistenceContext(unitName="PU2")
private EntityManager em2;
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW )
public void getCandidates(final Integer eventId) throws ControllerException {
ElectionEvent electionEvent = em.find(ElectionEvent.class, eventId);
...
Person person = getPerson(candidate.getLogin());
...
}
@TransactionAttribute(TransactionAttributeType.REQUIRES_NEW )
private Person getPerson(String login) throws ControllerException {
Person person = em2.find(Person.class, login);
return person;
}
Those methods are annotated with REQUIRES_NEW transcaction to avoid this exception. When I was calling these method from javaFX applet, all worked as expected. Now I'm trying to call them from JAX-RS webservice (I don't see any logical difference as in both cases ejb was looked up in initial context) and I keep getting this exception. When I set up XADatasource in glassfish 2.1 connection pools, I got nullpointer exception on em2.
Any ideas what to try next?
Regards
