Sounds like your webapp doesn't reinitialize itself properly, but is simply=
 assuming the existence of objects based on session existence - an invalid =
assumption.  Again, you should be using context listeners for that, not ses=
sion ones.

Yes - a ServletContextListener (or perhaps a HttpSessionActivationListener)=
.  If you simply want to prevent session persistence, configure your <Conte=
xt> to not do so:
