(sorry for this rePost but I think someone should be able to answer this).
For a new project, I need to decide whether its suitable to use session
beans or a servlet/jsp approach is enough.

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

Hi,
is it not possible to have a static field in the Session Bean, I mean it is

All,
We often think of using Entity beans to represent rows or entities in a database, but not much else. Is it a good idea to use an entity bean to represent entries in an LDAP directory? I was thinking aboutu throwing together a BMP entity bean to do this. It would always be in a read-only
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.

I'm tinkering with JBoss by extending the CMB CD example from the
