HttpSession retrieval with sessionId

Question

I'm working with stateless EJB, passing in its methods objects included in
          HttpSession objects. Of course RMI serialization prevents me to update the
          objects in the HttpSession, but their copies.
          To achieve this, could I pass sessionId, and from the EJB retrieve the
          original HttpSession object?
          I see the HttpSessionContext interface has the method getSession(sessionId),
          but it's deprecated. Is there anything similar?
          Any help would be appreciated
          

Answer 1

HttpSession session = request.getSession(false);
log("SESSIONID> " + session.getId());
log("CREATIONTIME> " + session.getCreationTime());
log("ISNEW> " + session.isNew());
When I use this bit of code, I'm getting a NullPointerException on the methods for the session object.
The getSession(false) always returns null. Even with this piece of code, I'm
receiving different sessionID's for the same session.
     HttpSession session = request.getSession(false);
     if (session == null) {
          session = request.getSession(true);
     log("SESSIONID> " + session.getId());
     log("CREATIONTIME> " + session.getCreationTime());
     log("ISNEW> " + session.isNew());
