RemoteObject throwing "Send failed" error

Question

I'm trying to read some data through a java class using Tomcat and blazeds.  I'll post some of my config and code here.
Here's the destination block of my remoting-config.xml
   <destination id="olapQuery">
      <properties>
         <source>com.zencos.OLAP.OLAPQuery</source>
         <scope>application</scope>
      </properties>
   </destination>
Here is where I setup the RemoteObject in my mxml
    <mx:RemoteObject id="olapQuery" destination="olapQuery">
        <mx:method name="query" result="olapQueryHandler(event)"/>
    </mx:RemoteObject>
Here's my olapQueryHandler method
            private function olapQueryHandler(event:ResultEvent):void {
                var olapData:ArrayCollection = event.result as ArrayCollection;
I call the remote object in a method called initApp that is called by the preinitialize event, like this
<mx:Application
    xmlns:mx="http://www.adobe.com/2006/mxml"
    xmlns:ilog="http://www.ilog.com/2007/ilog/flex"
    layout="absolute"
    preinitialize="initApp()"
    creationComplete="complete()">
Here is the method
            private function initApp():void {
                olapQuery.query(["TimeYQM"],["ServiceOrder"],["Trouble_Ticket_countSUM"]);
And here is the error I'm seeing when the application starts:
[RPC Fault faultString="Send failed" faultCode="Client.Error.MessageSend" faultDetail="Channel.Connect.Failed error NetConnection.Call.Failed: HTTP: Status 404: url: 'http://localhost:8080/Dashboard/messagebroker/amf'"]

    at mx.messaging.channels::AMFChannel/statusHandler()[C:\autobuild\3.2.0\frameworks\projects\ rpc\src\mx\messaging\channels\AMFChannel.as:390]
Where am I going wrong here?  I'm sure I've missed a step but I can't see where in any of the documentation.  I can supply any other information needed to figure this out.
Thanks for the help

A followup to my post.
When I try to go to http://localhost:8080/Dashboard/messagebroker/amf
I'm getting a 404 error.
I hope someone can help with this.  I'm seeing similar errors all over the forums but no helpful resolutions.
