Session.isNew() problem

Oct 31st, 2009

When my servlet creates a session, even if it is the first time running the servlet, the session.isNew() returns false. I checked to make sure the session ID's are different each time I run it and they are, yet isNew() still returns false.

I'm trying to do the following in my servlet:

 Help with Code Tags 
 JSP Syntax (Toggle Plain Text) 
HttpSession session = request.getSession(true);
if (session.isNew())
{
                ...do something...
}
HttpSession session = request.getSession(true);
if (session.isNew())
{
                ...do something...
}

It never gets into that if statement because it always returns false

Any help would be appreciated.

First of all when you have questions such as this, always search the API.

http://java.sun.com/javaee/5/docs/ap...n.html#isNew()

http://java.sun.com/j2ee/sdk_1.3/tec...ssion(boolean)

From the create session method, you see that it doesn't always create a new session. That call is the same as the no argument getSession() . The only difference is when you enter false. Then if there is no session it returns null.
But if you put true, it will not create a new session if one already exists.

I know that the above might no solve your problem because I just quoted the API, but have you tried running the session.invalidate() method first?
