Hello!

How do I get an EntityManager or EntityManagerFactory using JNDI? What are their JNDI names?

Thank you.

You can use the JNVIView mbean to see all of the names in JNDI.

I have done some research on this topic and I had to do this to get an EntityManagerFactory using JNDI:

In my persistence.xml:

<properties>
 <property name="jboss.entity.manager.factory.jndi.name" value="java:/persistence/solicitacoes" />
</properties>

Now I can use the code:

EntityManagerFactory emf = (EntityManagerFactory) new InitialContext().lookup(
 "java:/persistence/solicitacoes");
EntityManager em = emf.createEntityManager();

Is this the "official" way or is there a simple one?

Yes, that is the official way.
