Hi,
as Martin said this kind of "strong" interaction is not part of standard
API. But you could do a very simple thing to warn your users: start a
Javascript time-event with session timeout as time-interval:
http://www.w3schools.com/js/js_timing.asp.
I.e:
var t=setTimeout("/alert('Back to your job lazy user!!') /", <session
timeout in millisecond minus something....>);
The servlet API doesn't provide such notifications.
The only way to do this that I see is to track the times for each user
in your code.
But even then you'll have to send the notification to the browser and
here comes the question - how?

Hi,
I want to be able to show a Warning message appear when the session is
about to expire (say 5 minutes before) and if the session has expired then
on the UI it should come. This is to ensure a User does not enter any data
and lose it when they click Submit.
Use Case I wanna prevent: Lazy User goes for Coffee, comes back completes
Form, presses Submit ...curses me!
thanks
