Frank, Guru Thank you guys so much for the comments. But I forget to mention that the code was originally coded to request.getSession(false). Since it did not work for me, I changed to request.getSession(true). So neither was working for me. Angelina

"Returns the current HttpSession associated with this request or, if there is no current session and create is true, returns a new session." That "OR, IF" clause is whats important.. it should only create a new session if none already exists. So, calling getSession(true) is going to return to you a session either way, whether it's a pre-existing one or a new one. I do however agree that calling getSession(true) in this case does not seem appropriate... Angelina, I would call it with false and check for null, as Guru says. It probably won't solve the problem, but it will tell you a little bit more, namely whether the session really exists or not in a more explicit manner. -- Frank W.
