Web service newbie question

[thomas_revesz]

Hi!
I have deployed my first web service on JBoss 4.0.4. It is a simple HelloWorld type of service with one method that takes a string argument and that returns a string. I used WSTOOLS to generate the descriptor files and everything went smoothly. The deployment also went smoothly and JBoss loaded the service without problems. I then used the service http://www.soapclient.com/SoapClient to generate a test call to my service. However, the client returns with the message 'env:ClientEndpoint {http://test.my/}HelloPort does not contain operation meta data for: {http://test.my/}String_1', which is also shown as a SOAPFaultException on the JBoss console. Unfortunately, I'm too new at this to understand the message; how can such an error occur when I have used the provided tools to generate the descriptor files and what should I do to correct it? Any help would be appreciated. Here are the wstools config file and the WSDL if that is of any help:

<configuration xmlns="http://www.jboss.org/jbossws-tools">
 <java-wsdl>
 <service name="HelloService" style="rpc" endpoint="my.test.Hello"/>
 <namespaces target-namespace="http://test.my/" type-namespace="http://test.my/types"/>
 <mapping file="jaxrpc-mapping.xml"/>
 <webservices servlet-link="HelloWS"/>
 </java-wsdl>
</configuration>

<?xml version="1.0" encoding="UTF-8"?>
<definitions name='HelloService' targetNamespace='http://test.my/' xmlns='http://schemas.xmlsoap.org/wsdl/' xmlns:soap='http://schemas.xmlsoap.org/wsdl/soap/' xmlns:tns='http://test.my/' xmlns:xsd='http://www.w3.org/2001/XMLSchema'>
 <types/>
 <message name='Hello_getHello'>
 <part name='String_1' type='xsd:string'/>
 </message>
 <message name='Hello_getHelloResponse'>
 <part name='result' type='xsd:string'/>
 </message>
 <portType name='Hello'>
 <operation name='getHello' parameterOrder='String_1'>
 <input message='tns:Hello_getHello'/>
 <output message='tns:Hello_getHelloResponse'/>
 </operation>
 </portType>
 <binding name='HelloBinding' type='tns:Hello'>
 <soap:binding style='rpc' transport='http://schemas.xmlsoap.org/soap/http'/>
 <operation name='getHello'>
 <soap:operation soapAction=''/>
 <input>
 <soap:body namespace='http://test.my/' use='literal'/>
 </input>
 <output>
 <soap:body namespace='http://test.my/' use='literal'/>
 </output>
 </operation>
 </binding>
 <service name='HelloService'>
 <port binding='tns:HelloBinding' name='HelloPort'>
 <soap:address location='REPLACE_WITH_ACTUAL_URL'/>
 </port>
 </service>
</definitions>

Thanks for helping out!
