Hi Laird,
I think the problem may be to do with the rules of SSBs when
interfaces are implemented as such SSBs define more than one reference.
Jersey will look up the EJB using the class name to derive the
portable JNDI name, and i think the reference obtained from JNDI does
not implement ContextResolver. Need to verify.
