I thought that at first too Guru, I had to go remind myself... looking at the javadoc for request.getSession(boolean)...
"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.
