Calling a web service via soap

[aslocal]

Hello. I'm trying to call a webservice via SOAP. I keep getting this exception:

javax.xml.rpc.JAXRPCException: Cannot create SOAPFault message for: javax.xml.rpc.soap.SOAPFaultException: setProperty must be overridden by all subclasses of SOAPMessage

My class looks like this:

@Stateless
@WebService(serviceName = "ListingWebService")
@SOAPBinding(style = SOAPBinding.Style.RPC, use=SOAPBinding.Use.LITERAL)

public class ListingWebService {
public ListingWebService() {
}

@WebMethod(operationName="HelloWorld")
public String setHelloMessage(String test) {
return "Hello This is my first EJB3.0 webservice developed in JDeveloper and deployed on the glassfish platform";
}
}

My SOAP message looks like:

<?xml version="1.0" encoding="UTF-8"?>
<SOAP-ENV:Envelope
SOAP-ENV:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:SOAP-ENC="http://schemas.xmlsoap.org/soap/encoding/"
xmlns:xsi="http://www.w3.org/1999/XMLSchema-instance"
xmlns:SOAP-ENV="http://schemas.xmlsoap.org/soap/envelope/"
xmlns:xsd="http://www.w3.org/1999/XMLSchema"
>
<SOAP-ENV:Body>
<ns1:HelloWorld xmlns:ns1="http://webservice.ejb.smile4u.com/jaws" SOAP-ENC:root="1">
<v1 xsi:type="xsd:string">boo</v1>
</ns1:HelloWorld>
</SOAP-ENV:Body>
</SOAP-ENV:Envelope>

My WSDL is as follows:

<?xml version="1.0" encoding="UTF-8"?>
<definitions name="ListingWebService" targetNamespace="http://webservice.ejb.smile4u.com/jaws" xmlns="http://schemas.xmlsoap.org/wsdl/" xmlns:tns="http://webservice.ejb.smile4u.com/jaws" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/">

 </operation>
 </portType>
 <binding name="ListingWebServiceBinding" type="tns:ListingWebService">
 <soap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
 <operation name="HelloWorld">
 <soap:operation soapAction=""/>
 <input>
 <soap:body use="literal"/>
 </input>
 <output>

 </output>
 </operation>
 </binding>
 <service name="ListingWebService">
 <port name="ListingWebServicePort" binding="tns:ListingWebServiceBinding">
 <soap:address location="http://2fast:8080/smile4u/ListingWebService"/>
 </port>
 </service>
</definitions>

What am I doing wrong?

Thanks, Graeme.
