Java Programming

i want to expire the my browser session in case of user inactivity for 1 minutes in my web application? I tried doing two things :-

Approach1:- put the below code in web.xml

<session-config>
<session-timeout>1</session-timeout>
</session-config>

Approach2:-

session.setMaxInactiveInterval(1*60);

Both the aproaches does not expire the session. I am ablke to continue even if user does not do the activity for 3 minutes?


When it is not working:- it does not work when when i go to login screen directly and do the login.

when it works:-Though same approach works when i integrate above web application to with one of mine different web application say webapp2. What happens in this case i provided a link on webapp2 which directly takes me to webapp1 without asking login credentials. Here log out works in case user does not do the activity for 1 minutes?


i am not getting why it is not working in first case when i do the log in manually though web.xml is same and class where i put session.setMaxInactiveInterval(1*60) is executed in both the cases?
