Moodle auth/joomdle not working (DB not updated)

Without the $context, both work fine, that's why I was suspecting some kind of Moodle security restriction.
With the $context, google sends back a "405 Method not allowed", logical.

I can also get the same "faultCode 713..." error message calling:
$response = file_get_contents(" localhost.com:8888/moodle/mnet/xmlrpc/server.php k"); // without $context

And since I can call the Joomdle-Joomla joomdle.getUserInfo, I think the problem is a Moodle (or Joomdle on the Moodle side) configuration.

What more can I test to isolate the problem ? Is there a way to simplify the call ?

Since the "system_check" or "test" do not take arguments, should I be able to call them with a GET request ?
(On my system this actually gives the same error)

$request = xmlrpc_encode_request("auth/joomdle/auth.php/test", array());
$context = stream_context_create(array('http' => array(
'method' => "GET",
'header' => "Content-Type: text/xml ",
'content' => $request
)));

Do you know if there is there a Moodle function I can try to call through XML-RPC with a request like this ?

By the way, I'm using the last 1.9.9+ Moodle version (build 20100728).

Thanks again for your help Antonio!

Yes, the following code works just fine :

$username='julien';
$request = xmlrpc_encode_request("joomdle.getUserInfo", array ($username));
$context = stream_context_create(array('http' => array(
'method' => "POST",
'header' => "Content-Type: text/xml",
'content' => $request
)));
$response = file_get_contents(" localhost.com:8888/joomla/xmlrpc/index.php",false k, $context);

What is the last version of Moodle tested on ?
I just compared 1.9.9 from the one I use, there is not change at all in the mnet package...

Out of despair, I tried on port 80 too, but it fails the same way.
I'm going to test right now on another machine.

I installed a fresh Moodle 1.9.9+ on another machine (let's call it B, and let's call my laptop A).

B's configuration:
- LAMP
- PHP 5.3.2

A's configuration:
- MAMP
- PHP 5.2.13 with XML-RPC taken from Moodle bundled MAMP.

Still using only the test script, calling Joomdle service on B from A, it works. Nice to see

Then I installed a fresh Moodle 1.9.9+ on my machine (A) too : calling the new Joomdle service on A from B fails with the same error. Just to make sure it was not a configuration error, I used B's fresh database from A's moodle files : same error.

My conclusion: Something in my environment is causing some problem in the Moodle XML-RPC server.

We are still running some tests here to try to understand exactly what's failing.
