Web services

hi!

is there a way to tell moodle webservice to use a specific wsdl file while generating response?

moodle generates the following code whitout wsdl  (snippet)

<ns1:mn_resultWritebackResponse>
 <return xsi:type="ns2:Map">
 <item>
 <key xsi:type="xsd:string">usernames</key>
 <value SOAP-ENC:arrayType="xsd:string[2]" xsi:type="SOAP-ENC:Array">
 <item xsi:type="xsd:string">user1</item>
 <item xsi:type="xsd:string">user2</item>
 </value>
 </item>
 <item>
 <key xsi:type="xsd:string">secret</key>
 <value xsi:type="xsd:string">hash</value>
 </item>
 </return>
 </ns1:mn_resultWritebackResponse> 

and do this way for any array output.

but I want something like this:

<ns1:mn_resultWritebackResponse>
 <usernames xsi:type="ns1:usernameList">
 <username xsi:type="xsd:string">user1</username>
 <username xsi:type="xsd:string">user2</username>
 </usernames>
 <secret xsi:type="xsd:string">hash</secret>
 </ns1:mn_resultWritebackResponse>

which is generated automatically if I enter wsdl file location in lib/Zend/Soap/Server.php line 167:

$wsdl='location/to/wsdl/file.wsdl';

I know that Zend_Soap_Server allow to set wsdl with it's method setWsdl(), but I cannot find any settings in moodle, or any possibility in the webservice 'external_api' and in it's methods.

This option could be set somewhere in webserivce/lib.php line 698, in the public function run, where the zend_soap_server is initalized, if the function or the class (webservice_zend_server and it's derivatives) itself would have such options.e

the corresponding wsdl snippet:

...
<xsd:complexType name="usernameList">
 <xsd:sequence>
 <xsd:element name="username" type="xsd:string"
 maxOccurs="unbounded" />
 </xsd:sequence>
 </xsd:complexType>
...
<wsdl:message name="resultWritebackResponse">
 <wsdl:part name="secret" type="xsd:string" />
 <wsdl:part name="usernames" type="tns:usernameList" />
 </wsdl:message>
...

and the external_api's _returns() function:

public static function resultWriteback_returns() {
 
 return new external_single_structure(
 array('usernames'=>
 new external_multiple_structure (
 new external_value(PARAM_TEXT,'username')),
 'secret'=>new external_value(PARAM_TEXT,'secret')
 )
 );
 }

Any idea? thanks!
