Major Description
At the moment geronimo trunk is not using the openejb constructed jndi tree. Amazingly this pretty much works except for the cmp jpa persistence context which is looked up in the openejb constructed tree but currently only bound in the geronimo one.
Pending better integration of jndi trees between openejb and geronimo, I'm going to fall back to new InitialContext().lookup(...) if the lookup in the context from deploymentInfo fails.
This should be fixed before an openejb release.
