[flexcoders] How to acces POST of REST Service thru Flex (Couldn't establish a connection)

[bjgindia]

Hi,

I have got the REST POST working thru simple HTML Form submit.
This REST Service takes an XML and returns back an XML.

But, when I tried it with FLEX, I am getting "Couldn't establish a
connection" errors:

FLEX CODE:

<?xml version="1.0" encoding="utf-8"?>
<mx:Application xmlns:mx="http://www.adobe.com/2006/mxml";
layout="absolute">
     <mx:HTTPService id="RESTService"
         method="POST"
        
destination="http://10.176.95.32:8889/SunRestTest/sunTest/testRest";
         resultFormat="e4x">

      <mx:request xmlns="">
       {this.payload}
      </mx:request>
     </mx:HTTPService>

     <mx:Script>
         <![CDATA[
             private function processValues():void {
                 RESTService.send();
             }
         ]]>
     </mx:Script>

<mx:VBox width="100%" height="100%">
<mx:Form width="100%" height="50%">
         <mx:FormItem label="Payload" width="100%" height="100%">
             <mx:TextArea id="payload" width="100%" height="80%"
                 text="Paste or Type the XML Payload here:"/>
             <mx:Button
                 label="Submit"
                 click="processValues();"/>
         </mx:FormItem>
     </mx:Form>

     <mx:TextArea width="100%" height="50%"
         text=
           "{RESTService.lastResult.toString()}"/>

</mx:VBox>

</mx:Application>

FAULT ON Clicking the Submit Button:

[RPC Fault faultString="[MessagingError message='Destination
