Re: Minimalistic JPA in GWT 2.1.0.M3

Thanks for the reply. I'm doing something wrong because I'm getting
the same error even when I place persistence.xml to /war/META-INF.
javax.persistence.PersistenceException: No Persistence provider for
EntityManager named Domain

The exception is thrown in both hosted and stand-alone mode. I'll try
to configure JTA transactions first before doing anything else with
the JPA.
