Coldfusion Instant Message Example?

In the Coldfusion Admin, under Gateway Instances I have configured the following:

Gateway ID: helpdesk

Gateway Type: XMPP - Handles XMPP instant messaging

CFC Path: C:\ColdFusion9\gateway\cfc\helpdesk\im.cfc

Configuration File: C:\ColdFusion9\gateway\config\helpdesk_ejabberd_local.cfg

After I start the "helpdesk" event and check the eventgateway.log there is the following mesage:

Error invoking CFC for gateway helpdesk: Cannot lock APPLICATION scope.  {ORIGINATORID={lucas@jabber.com},CFCMETHOD={onBuddyStatus},GATEWAYID={helpdesk},DATA={{buddystatus={OFFLINE},buddynickname={Lucas},RECIPIENT={me@localhost},buddygroup={Helpdesk  Staff},timestamp={Wed Aug 10 15:11:29 EDT  2011},buddyname={lucas@jabber.com}}},CFCPATH={C:\ColdFusion8\gateway\cfc\helpdesk\im.cfc},GATEWAYTYPE={XMPP}}.  Cannot use cflock to lock the application or session shared scopes without these  scopes being established through the use of the cfapplication tag. To use the  session scope you need to enable session management. Application and/or Session  variables must also be enabled in the ColdFusion Administrator.

However, Event Status says that it is running.

When I run the sample index page and I do see a message that says "The helpdesk is currently ONLINE."

But when I attempt to Add a new issue --- I receive the following:

The error occurred in C:\Inetpub\wwwroot\DEV_Helpdesk\cfc\helpdesk.cfc: line 25
