When you say "web app", I assume you mean a separate web context and not a single context on separate machines?
If you are, then sessions don't work that way. A session is specific to an application context, and while the session ID in some containers may be the same between contexts, the session itself is not. It is possible to create messages between web applications, but you may find it better to have a 'common area' such as shared Database or business tier to allow the applications to communicate.
Be careful that you don't try to replicate the session's responsibility though. Doing so is dangerous since it may not be completely compatible with the existing session mananger and prevent clustering, or it may cause the original session manager to become unstable.
I hope this helps.
