I can just give you pointers where to look at but can’t solve the issue with the details provided.

What is the session timeout you have set in web.xml?
As you have said that you are running from the same server, but from a different port, the cookie to maintain Sessions should be different for both of these applications.

I think the later would be the cause for your problem rather than from the former.
