If you want to make it read only, will JBoss allow you to write the
remote interface such that it only has getters?The M-H book suggests
not even exposing the remote interface for enitity beans. Certainly it
would be preferable to have on the getters available to most clients.

Hey Tim,
If I correctly understand your qutestion, this is more of a servlet type session
management issue. Take a look at the javax.servlet.http.HttpSessionBindingListener
interface. It's basically a callback interface for when a session expires. Objects
