So, it's not propigating subject between EJB's if they're called through the interface returned from JNDI, but it is propogating it with injection? I would have thought that the injection reference would have come from JNDI to begin with. Does JBOSS have a parallel reference mechanism with JNDI so that the JNDI reference is different from an injected reference? It may take some time for me to try this, but if it does work I probably can't depend on it for a long term solution. The code is layered with pluggable components so it's not going to take well to having one EJB hard bound to another through an annotation reference. Is there some way to enforce subject propigation using an JNDI reference using something like Subect.doAs?
