This is the V3 trunk, active development. I've been tasked with
implementing MEJB, the JSR 77 Management EJB.
I'm a newbie at EJB, any ideas are appreciated— I'm having a problem
where PortableRemoteObject.narrow() returns null.
The app is deployed fine:

My test code is below. When I run it, an IOR exists, so I presume
this means that the ejb can be seen and referenced.
But I get null from PortableRemoteObject.narrow().
Got ref: IOR:
