No, works as I would infer from: "EJB3 Persistence Spec 5.5.1" wrote : A JTA entity manager participates in the current JTA transaction, which is begun and committed external to the entity manager and propagated to the underlying resource manager. My interpretation would stipulate that the EM would have to be created in the presence of a JTA Transaction, hence my educated guess earlier. JBoss EJB3 delegates these operations out to the JPA Persistence Provider, in our case, Hibernate EM. So if you've got more detailed questions I'd ask over on the Hibernate forums.
