Creating WSDL

Hi, I'm trying to write a simple wsdl file for the PHP SOAP client/server code at http://www.edoceo.com/liberum/?doc=using-pear-soap I think I'm pretty close but still can't see where I'm going wrong so I thought I'd post a message. If you'd like to help debug my wsdl please read on. The code is a simple 'echo text' php soap server. I'm seeing this error message: array(5) { [0]=> string(83) "method '{http://rudistarcevic.net/site/soapx/echo}test_soap' not defined in service" [1]=> string(15) "SOAP-ENV:Server" [2]=> NULL [3]=> NULL [4]=> Here is the wsdl code I've written: <?xml version="1.0" encoding="UTF-8"?> <definitions xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:http="http://schemas.xmlsoap.org/wsdl/http/" xmlns:xs="http://www.w3.org/2001/XMLSchema" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/" xmlns:mime="http://schemas.xmlsoap.org/wsdl/mime/" xmlns:y="http://www.rudistarcevic.net/site/soapx/echo" targetNamespace="http://www.rudistarcevic.net/site/soapx/echo"> <message name="echo_text"> <part name="p_one" type="xs:string"/> <part name="p_two" type="xs:string"/> </message> <message name="echo_reply"> <part name="p_echo" type="xs:string"/> </message> <portType name="SOAP_testPortType"> <operation name="test_soap"> <input message="y:echo_text"/> <output message="y:echo_reply"/> </operation> </portType> <binding name="SOAP_testBindng" type="y:SOAP_testPortType"> <soap:binding style="rpc" transport="http://schemas.xmlsoap.org/soap/http"/> <operation name="test_soap"> <soap:operation soapAction="http://www.rudistarcevic.net/site/soapx/echo"/> <input> <soap:body use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://rudistarcevic.net/site/soapx/echo"/> </input> <output> <soap:body use="encoded" encodingStyle="http://schemas.xmlsoap.org/soap/encoding/" namespace="http://rudistarcevic.net/site/soapx/echo"/> </output> </operation> </binding> <service name="SOAP_test"> <port name="SOAP_testPort" binding="y:SOAP_testBindng"> <soap:address location="http://www.rudistarcevic.net/site/soapx/echo/server.php"/> </port> </service> </definitions> Many thanks Regards Rudi.
