Thank you all for your help. I think we have it resolved and it was indeed
the WLCookieName parameter (JSESSIONID) in the weblogic plugin that was set
incorrectly. This has led to heavy discussion however with regards to this
question:
Is it really a good idea to implement the SessionAware interface and use a
separate Hashmap to hold the user's session data? Would it not be perhaps
safer and more efficient (and reduce the possibility of clustered session
replication issues) to simply get the session yourself and set the
attributes directly into it? What benefit is there to making struts the
middleman and using a separate Hashmap? We are having this debate currently
at my co. and I am lacking a convincing reason to avoid dealing directly
with the session.  THanks!




You can configure sticky sessions, which means that requests that go to one
server in your cluster will always go to that server. To me this defeats the
purpose of the cluster because if that machine goes down the user will be
sent to another server, but their session will be gone with the down server.
However this is the best performing configuration. Another option is shared
sessions and this is covered in the WebLogic documentation at
http://edocs.bea.com. How or if the session is shared in a cluster has
nothing to do with Struts or any web application really.
