I do not know if this question belongs here ... but
I believe that this is impossible . The very reason being HTTP is stateless . When the window object is closed there are no events to capture this . That is the idea of having an explicit logout item that you can capture . Another way would be to write a HTTP Sessionbinding listener . Here the value unbound event will be raised when the session expires (window with no activity for a set amount of time ) then you may be able to do a session invalidate.
You may be able to search about widow close in either the servlet or jsp forum to get many leads
