XML-RPC via HTTPService

Question

I'm trying to make an XML-RPC call via an HTTPService
instance. Is that the best way to do it?
At present I can generate a request to the correct URL, but
the POST seems to be empty. I think that I don't understand what
should go in the <mx:request> tag -- I have the literal XML
which I want sent:
<mx:HTTPService
id="loginRequest"
url="
http://localhost:8080/rpc/xmlrpc"
useProxy="false"
method="POST"
contentType="application/xml"
resultFormat="e4x" >
<mx:request xmlns="" format="xml">
<methodCall>
<methodName>confluence1.login</methodName>
<params>
<param>
<value><string>{username.text}</string></value>
</param>
<param>
<value><string>{password.text}</string></value>
</param>
</params>
</methodCall>
</mx:request>
</mx:HTTPService>
Thanks for any advice.

Answer 1

I am having a similar problem, when I tried to read the
contents of the POST in ASP it is blank.
i'm sending some xml to asp from flex using the httpservice
but when I try to parse the xml using the standard Microsoft.XMLDOM
it always fails to parse the xml regardless of what xml I send.
This leads me to think that flex is sending the xml incorrectly.
flex code>
request = new HTTPService();
request.url="
http://127.0.0.1/test.asp";
request.contentType="application/xml"
request.method="POST"
request.resultFormat="text"
request.request = XML(<test>testingxml</test>);
request.addEventListener(ResultEvent.RESULT, success);
request.addEventListener(FaultEvent.FAULT, fault);
request.send();
private function success(e:mx.rpc.events.ResultEvent):void {
trace(e.result);
private function fault(e:mx.rpc.events.FaultEvent):void {
trace(e.message);
my ASP code>
Dim mydoc
Set mydoc=Server.CreateObject("Microsoft.XMLDOM")
mydoc.async=false
mydoc.load(Request)
Response.ContentType = "text/xml"
if mydoc.parseError.errorcode<>0 then
Response.write "<prob name='fail'>blah</prob>"
else
Response.write "<prob name='works'>yay</prob>"
end if
The asp script always sends <prob
name='fail'>blah</prob> back to flex meaning that the xml
failed to parse correctly. The xml is correct, if I load the same
xml from a text file it will parse correctly, it only fails when
the xml is loaded from flex.
Does anyone know the exact format that the xml is sent in
using the httpservice.send() method? I tried using Request.Form in
ASP but it only gives the error printed at the bottom of this post.
BTW is there anyway to get flex to trace error messages given
from ASP when a script fails as I can't read them in a browser
(because the request is sent using POST). When ASP gives an error
flex either does not respond or gives this error which does not
help my cause.

EDIT:
I wrote the value of the ASP request (sent from flex) to a
text file and I ended up getting blank, in other words no XML. Now
i'm not even sure if flex is sending any xml.
