--------------------------------------------------------------
I have an EJB3 stateless session bean deployed in AS 5.1.0 that I am trying to look up from some client code deployed in a remote AS 4.0.5 installation. The client isn't a true EJB client, just something that happens to be running within the context of a 3rd party EJB in that server. Should this be possible? The client has the same class files inside its jar as those in the 5.1.0 bean's jar. I specifically set the JNDI provider URL to be the remote 5.1.0 server in the InitialContext properties before lookup.

I get this exception during the narrow() call:
