Let me add, that I figured the best way to do this would be to listen
for Deployment Notifications, then I would be able to look up the newly
registered ObjectNames for the deployed EJB's. This would allow me to
determine the JNDI name, get a copy of its Local Interface and invoke
methods based on deployment and undeployment. But as I noted in a
previous email Deployment Notifications occur prior to actual deployment
so queryNames returns no results, and therefore this approach isn't
feasible either (without modifying JBoss).
It would be better to be able to implement the postRegister methods as I
mention below.
