[flexcoders]Faking an XMLRPC call

[dorkie dork from dorktown]

Is there a way to fake an XML RPC call? It seems like it'd be simple but I
can't get it to work:

   <mx:HTTPService id="srv"
       url="http://www.judahfrangipane.com/blog/xmlrpc.php";
       fault="{faultHandler(event)}"
       result="{resultHandler(event)}"
       resultFormat="text"
       method="POST"
       contentType="application/xml">
       <mx:request>
           <methodCall>
               <methodName>metaWeblog.getPost</methodName>
               <params>
                   <param><value><string>77</string></value></param>
                   <param><value><string>visitor</string></value></param>
                   <param><value><string>visitor</string></value></param>
               </params>
           </methodCall>
       </mx:request>
   </mx:HTTPService>

The result I get is "XML-RPC server accepts POST requests only."

FYI I'm calling a wordpress blog.
