Hi,
How we are redirecting to the URL address for any of the screen in the application when the application is not in session.And how are we directing to the login page when an application is not in session.

Can you explain what you mean by "not in session"?

Let me explain clearly:

How to implement a single sign on?.

For instance, your organization may have a single portal for logging in users, whose login page resides at http://mycompany.com/SSOLogin.

If user is not logged in and tries to access application's page, they must be redirected to the login page. Assuming successful authentication, they should be redirected to the original resource they requested.How this process works?

well if the user is not logged in,
whenever he tries to make an access to the page in the
application you can always take him to the login page by checking
whether the user is in the session attribute.
as soon as ta user logs in and is validated, you store the userObject in
session. whenever he logs out or tries to make a access without logging in
you take hime to the login page.

A servlet filter is perfect for this task.

I've just added a war file to my simple.souther site.
http://simple.souther.us/SimpleLogin.war

If you have a servlet spec 2.4 compliant container, just download the war file to your webapps directory and give it a shot.
