[jboss-user] [JBoss Seam] - Re: Using the JPA delegate

[eirirlar]

It seems that the entityManager.getDelegate() returns either a SessionImpl or a EntityManagerImpl, depending on wether or not you have the following set up in your components.xml:

<core:managed-persistence-context name="bookingDatabase"
  |                        auto-create="true"
  | persistence-unit-jndi-name="java:/EntityManagerFactories/bookingData"/>

and persistence.xml:

<property name="jboss.entity.manager.factory.jndi.name" 
  |           value="java:/EntityManagerFactories/bookingData"/>

That is - if this is set up, SessionImpl is returned. Otherwise EntitiyManagerImpl is returned.

I can't really find a logical explanation for this, but it's not a problem as long as I know about it.
