The specs require that separate web apps, whether within one ear or  
in separate ears, have separate sessions with no overlap or sharing.   
However, it's possible to share session lifetimes across apps.  IIRC  
in Jetty this always happens and in tomcat you have to indicate that  
each app is cross-context and indicate a "context root" across which  
lifetimes will be shared.

If you want to actually share information between sessions for  
different web apps I think there's a way to use some kind of  
listeners for session changes to notify the other app that something  
changed: I'm not an expert on this and was told of it by some portlet  
guys so it might only be available with portlets.
