RE: [JBoss-user] behaviour of a cached initialContext
And about reusing homes (will JAAS principal be maintained?) The JAAS principal is not associated with the homes, you can safely cache them. The principal is associated with the current thread when the request is received. This thread local principal is then used by the proxy classes when the home (or bean) is accessed.

Re: [JBoss-user] behaviour of a cached initialContext
we have a cache manager that does that for reusable data (using refletion), we haven't solved the notification of change yet, since it will have a thousand of web clients (jboss light + tomcat) as the bank offices and a slow (delayed) satelite line.
