[flexcoders] Managing LCDS FlexSession with CF8

[Brendan Meutzner]

I am trying to figure out how to manage the session for a flex client which
is connecting to lcds/coldfusion instance.  I have determined the "logic"
behind the problem, but can't figure out how to implement using CF8.


 I'd like to be able to track login/logout (browser close) via
FlexSessionListener.  Here's the Java class I found to handle the events:


-----------------------

import flex.messaging.*;


public class SessionWatcher implements FlexSessionListener {


  protected FlexSession session;



  public SessionWatcher() {

    FlexSession.addSessionCreatedListener(this);

  }



  @Override

  public void sessionCreated(FlexSession session) {

    this.session = session;

    System.out.println("Session " + session.getId() + " has been created");

    session.addSessionDestroyedListener(this);

  }



  @Override

  public void sessionDestroyed(FlexSession session) {

    System.out.println("Session " + session.getId() + " has been
destroyed");

  }

}


--------------------------------


I've compiled this and placed it into the WEB_INF/classes directory, and
have successfully called it via CreateObject("java", "SessionWatcher").


However, this is as far as I've gotten.  I simply don't understand the
method in which I can "merge" this with my existing CFC file which is called
on client login to implement this.  Here's what I've tried:


---------------------------------


listenerClass1 = CreateObject("java", "SessionWatcher");


CreateObject('java',
'flex.messaging.FlexContext').getFlexSession().addSessionCreatedListener(listenerClass1);


CreateObject('java',
'flex.messaging.FlexContext').getFlexSession().addSessionDestroyedListener(listenerClass1);


--------------------------------


I'm either not finding the "System.out.println" output from the listener
functions when they are callled, or they're not getting called at all.



If somebody has done this before, then please give me some idea on how to
accomplish this.  However, if anybody can even point me in the right
direction for how you use Java files in CF that would be a help as well.



Thanks in advance,


Brendan
