Alerting the user about Session expiry after idle-time

Hello,

I have the Web application in which i am using Weblogic Server with jsps. My requirment is to alert user prior to the session expiry when he revisit the page after the idle-time.

ISSUE is:
"When a user is on a page for longer than the required time he is timed out. There is a time-out value on the server that I need to capture and produce an alert box on the page. "

SOLUTION tried:

For this i tracked the values from javax.servlet.http API

1.Login time,
2. time out value from web.xml
3.*idle time(Unable to get it).

Please suggest me the solution for this, I mean to say is there any readymade plug-in,reusble component for this.

If not then how can i track the idle time for multiple user.

Do reply me ASAP,

Thanks & Regards
Koti

If you know what the timeout is, you could simply set up a javascript timer upon site creation. Once time is up you display the notification.
