Subject AW: AW: How to keep track of sessions
Date Wed, 14 Aug 2002 16:08:06 GMT
The answer to your question: 
  
  the typical use is something like this:

  if (session.isNew()) {
    // store listener object in the session.
  }

  Now your Listener will be called when the session 
  is started (valueBound()) and when it ends (valueUnbound() 
  that's the one where you could kill the jobs)

To find out the number of active session you have to 
implement a Listener as above that increases an 'global' 
var with every valueBound() and decreases it with every 
valueUnbound().
