J2ee Session Tracking

In my servlet (after login) I set the session timeout interval as 30 seconds and also note the sessionID as say X

 session.setMaxInactiveInterval(30);

The servlet then forwards to a JSP page (intermediate1) which has a link to the second intermediate page (intermediate2). I don't do anything on the page for around 30 seconds (timeout interval) and then forward to the second jsp page (intermediate 2). Here I print the sessionID and it is NOT X. It is another value. How did this happen? Does the container automatically assign a session object to a JSP page if no session already exists? Kindly help.

Here is an interesting link I found on the web that answers my own question. FYI.

JSP spec (for JSP 2.1/JEE6 it is found in chapter "JSP.1.10.1 The page Directive") describes that the session implicit object is on by default, so that every call to a JSP will participate in an existing session/create a new session if needed. It can be turned off as:

<%@ page session="false" %>

Because of jsp implicit-object, then see one of them is 'session'.

So, jsp's implicate object always be there.

In your case, already current session object went off, but jsp api make it newly available.
