> [...] It's hard to tell what's wrong without really digging into the code for the whole application, but you obviously create the bean in the session scope. And like you suggest, the bean should therefore be available until the session terminates (by time-out or explictly invalidated) or is explicitly removed. The fact that it's in session scope means that there's at least one reference to it (from the data structure that implements the session collection), so it should not be GCed. Most likely your application loose track of the session ID at some point. For instance, if you use URL rewriting instead of cookie-based session tracking, a single link that is not rewritten means that the session ID is not passed to the server, so a new session is created. That's where I would start looking. Also, if you use servlets for some part of the application, make sure that the servlet and the JSP pages are always invoked with URLs containing the same context prefix (e.g. "/myapp/myServlet", "/myapp/mypage.jsp").
