Mostly I'm posting this here to chronicle my experience, but feel free to comment if you would like.

Ok, so I've been learning Flex in my spare time for a few weeks and have become okay when writing the basic stuff, but my real interest is in the remoting aspects. So I decided to try put a simple remoting application together. The goal is to create a page with just a button and a label. When the button is pressed, I want to communicate with a CFC that returns the current date and time.

So here's the Flex code:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml" layout="absolute">
   <mx:Script>
      <![CDATA[
         import mx.rpc.events.ResultEvent;
         
         public function eventSuccess(event:ResultEvent):void{
            lblStringResult.text = event.result as String;
         }
      ]]>
   </mx:Script>
   
   <mx:RemoteObject id="conn" destination="ColdFusion" source="cfflex.Demo1.Demo1CFC"
      result="eventSuccess(event)" showBusyCursor="true">
      
   </mx:RemoteObject>
   
   <mx:Label id="lblStringResult" y="10" horizontalCenter="0"/>
   <mx:Button label="Server Time?" click="conn.getServerTime();" y="36" width="100" horizontalCenter="0"/>
</mx:Application>

Pretty simple right? I have a mapping on the CF server with a logical directory of '/cfflex' and a directory path of '/Library/WebServer/Documents/svn/CFCLib' that contains a directory called Demo1 that, in turn, contains a CFC named Demo1CFC.cfc.

Here's the ColdFusion Code:

<cfcomponent output="false">
   <cffunction name="getServerTime" access="remote" returntype="string">
      <cfreturn now() />
   </cffunction>
</cfcomponent>

The problem is that every time I run the Flex page and press the button I receive the following error:

[RPC Fault faultString="[MessagingError message='Destination 'ColdFusion' either does not exist or the destination has no channels defined (and the application does not define any default channels.)']" faultCode="InvokeFailed" faultDetail="Couldn't establish a connection to 'ColdFusion'"]

My platform is an Intel Mac using Apache2 and ColdFusion 8 64bit.
