Non-WSDL mode

Hi all!

I have a little problem with Non WSDL Mode. I define classes for my 
complex types, but server seems to not recognize them.
My code:

soap_server.php
==============


/*-----------FUNCTIONS----------*/
**
 * Method to create an event subscriber
 *
 * @param SubscriberData $subscriber
 * @return unknown
 */
function CreateSubscriber( $subscriber )
{
}//function CreateSubscriber( $name )


/*------------CLASSES---------*/

class SubscriberData
{
  public $id;
  public $name;
 
}//class SubscriberData


/*----------------MAIN-----------------*/

$classmap = array('SubscriberData' => 'SubscriberData');
$server   = new SoapServer( null, array( 'uri' => 
'http://localhost/poc/', 'classmap' => $classmap ) );

$server->addFunction( 'CreateSubscriber' );

$server->handle( $GLOBALS['HTTP_RAW_POST_DATA'] );


REQUEST

xsi:type="xsd:string">Dani</value></item></param0></ns1:CreateSubscriber></SOAP-ENV:Body></SOAP-ENV:Envelope>

As you can see, Subscriberdata class is not recognized. It is something 
missing in my server constructor??

Thank you in advance!
