At this point, you might want to try something like this:
- If you don't have any objects that you put in sessions that
implement HttpSessionBindingListener, implement such an object, and
have your servlets put an instance of it in the session when you
put the rest of the stuff in the session.
- In the implementation of valueUnbound(HttpSessionBindingEvent event),
put some logging code to record what's happening. This listener method
will get called when the session times-out. I suggest something like this:
try
{
throw new Exception( "valueUnbound()" );
}
catch( Exception e )
{
e.printStackTrace();
}
This will print the call-stack at the point your session is going out
of scope.
- You might also save System.currentTimeMillis() in valueBound(), and
compare that to the syetm time in valuyeUnbound() to see how long the
session
was "alive".
This should at least give you some diagnostic info about what's happening to
your
sessions.
