Thanks for the reply and I have re-posted the message to the correct forum.

However, I don't understand your reference to request.getRemoteUser(). I use
this at various points in my application to determine the current user but
how can it tell me the time that user logged in or logged out?

Or do you mean some method of querying the session object used?

Thanks

Martin O'Shea.
