The first thing you should do is see what the session ID is--e.g., add,
System.err.println("Session ID="+req.getRequestedSessionId());
If it keeps changing, you're losing the session ID somewhere: for instance,
you might have cookies turned off and you aren't calling
HttpServletResponse.encode[Redirect]URL() on all your URLs.
