isNew returns false even when I have created a new session.Why is that ?

Question

In the following snippet,uSession.isNewalways returns false. Why is that ? I create a new session but the corresponding method returns false.

HttpSession uSession = request.getSession();
    if(uSession.isNew()) {System.out.println("Inside if statement---------");
        uSession.setAttribute("username", username);
        uSession.setMaxInactiveInterval(3600);
        RequestDispatcher dispatcher = request.getRequestDispatcher("User.jsp");
        dispatcher.forward(request, response);
    }

I have even tried after deleting all the localhost cookies from the browser.

Because HttpSession exists before request.getSession() called so isNew return false. Need to check where/time httpSession created before HttpSession uSession = request.getSession(); — LHA, Apr 16 '14 at 15:17
getSession(false) will not return a new Session if one does not already exist. and check if session is null or not — codefreaK, Apr 16 '14 at 15:19
@LuiggiMendoza new session ? You mean by passing a boolean ? — saplingPro, Apr 16 '14 at 15:20
@LuiggiMendoza Will this not automatically create a new session, if it doesn't exist ? — saplingPro, Apr 16 '14 at 15:22
getSession() = getSession(true). It will return existing HttpSession if the existing httpSession created BEFORE in somewhere. — LHA, Apr 16 '14 at 15:23
@SaplinPro: Ok. If the code block executed for the FIRST time ( first request), uSession.isNew() will return true, but for SUB-sequence requests, uSession.isNew will always return false because uSession created in the first request. — LHA, Apr 16 '14 at 15:42
@saplingPro: You mean it return false for the FIRST request? — LHA, Apr 16 '14 at 15:48
The reason may be your application server restore session data after stop/start. Check your WAS and restart it. — LHA, Apr 16 '14 at 15:59

Jsp automatically creates a session. I don't know why it creates. But it does. So your jsp automatically creates a session and that's why isNew() returns false all the time. The solution is to set the session to false in the JSP Page Directive. i.e., Use <%@ page session="false"%

isNew returns false even when I have created a new session.Why is that ?
