Unable to get simple DataService to work

Hi, I have been trying to get a simple DataService prototype
to work. I am using Flex DS 2.6 (the latest) with JBoss 4.0.3sp1
server. I have a very simple MXML application as follow:



<?xml version="1.0" encoding="utf-8"?>

<mx:Application xmlns:mx="
http://www.adobe.com/2006/mxml"
layout="vertical">

<mx:DataService id="fooService"
destination="fooAssembler" result="getAllHandler(event)"/>

<mx:Script>

<![CDATA[

import mx.rpc.events.ResultEvent;

import com.gemex.Foo;



[Bindable]

private var foo:Foo;



private function getAllHandler(event:ResultEvent):void {

foo = event.result as Foo;

}

]]>

</mx:Script>



<mx:TextInput id="fooId"/>

<mx:Button label="Retrieve"
click="fooService.getItem({id: int(fooId.text)})"/>

<mx:TextInput id="fooName" text="{foo.name}"/>

</mx:Application>



The server side configuration is as follow:



In data-management-config.xml, I have added the following:



<destination id="fooAssembler">

<adapter ref="java-dao"/>

<properties>

<source>fooAssembler</source>

<factory>spring</factory>

<metadata>

<identity property="id"/>

</metadata>

</properties>

<channels>

<channel ref="my-rtmp"/>

</channels>

</destination>



In data-management-config.xml, I have added the following:



<factories>

<factory id="spring"
class="com.gemex.arch.flex.factories.SpringFactory"/>

</factories>



When I run the sample, I get the following message in the
browser:



[RPC Fault faultString="There was an unhandled failure on the
server. null" faultCode="Server.Processing" faultDetail="null"]

I also got a bunch of output from the JBoss console, but it
is too long to list here. Let me know if that would help. I was
able to make a similar example work with the LCDS 2.5. I have been
banging my head for over 3 days now. Hope someone has some insight
as to what I should try next.



Thanks much,

Ben

In case the JBoss console output is useful, here is the
output from the LCDS classes:
