How-to clear the session values from the jsp page?

session.invalidate() . But you need to refresh page to take effect. Note that generally that the session truly ends only when the browser window closes.

The six most commonly used methods to invalidate a session are

• Calling HttpSession.setMaxInactiveInterval(int secs) method, explicitly setting how many minutes the session will last.

• The session will automatically be invalid after a certain time of inactivity (Tomcat default is 30 minutes). You need to remember that this 30 minutes is not a hard and fast rule for all servers. It might vary from one server to another and is configurable. So you can have it configured to last 25 mins in your server and I can have it to last 20 mins.

• The user closes all browser Windows. Note that, here the session will timeout rather than directly triggering a session invalidation.

• The session will expire when it is explicitly invalidated by a servlet by calling invalidate().

• The server is stopped or crashes. Note that this event might not trigger a session invalidation. A Web container that permits failover might persist the session and allow a backup Web container to take over when the original server fails.

• You can set the default timeout in the web.xml file ().
