[jboss-user] [Beginners Corner] - Should entities bind to JNDI?

[culli]

When I deployed an entity with EJB2/xdoclet I could specify a local-jndi-name in @ejb.bean and it would bind to a JNDI name.

How do I do this with EJB 3 annotations?  I'm using JBoss 4.2.3GA with no modifications and the first jboss example code from Enterprise JavaBeans 3.0 (Bill Burke/Richard Monson-Haefel).  Very basic stuff.  I can run the test client just fine.

I'm checking the JNDIView bean for the Cabin bean and it's not there, but I can see the TravelAgent session bean.  At some point I need to be able to look up my EJB 3 beans from legacy EJB 2 stuff that won't be converted (at least not within a year or so), so doesn't the EJB 3 entity need to be bound in JNDI?
