WebResult annotation: targetNamespace problem

I found a problem with the targetNamespace attribute of the JAXWS WebResult annotation:

Here is a simple service:

package com.mycompany.services;

import javax.jws.WebParam;
import javax.jws.WebResult;
import javax.jws.WebService;
import javax.jws.soap.SOAPBinding;
import javax.jws.soap.SOAPBinding.ParameterStyle;
import javax.jws.soap.SOAPBinding.Style;
import javax.jws.soap.SOAPBinding.Use;

import com.mycompany.beans.ReturnStructure;

@WebService(name="MyService", targetNamespace="http://mycompany.com/myService")
@SOAPBinding(style=Style.DOCUMENT,
use=Use.LITERAL,
parameterStyle=ParameterStyle.WRAPPED)

public class MyService
{
@WebResult(name="ReturnStructure", targetNamespace="http://mycompany.com/beans")
public ReturnStructure doSomething(@WebParam(name = "parameter")int parameter)

}

The ReturnStructure class is generated from the XSD below using JAXB2:

<?xml version="1.0" encoding="UTF-8"?>
<schema targetNamespace="http://mycompany.com/beans" elementFormDefault="qualified" xmlns="http://www.w3.org/2001/XMLSchema" xmlns:tns="http://mycompany.com/beans">

<complexType name="ReturnStructure">
<sequence>
<element name="code" type="string"></element>
<element name="subcode" type="string"></element>
<element name="message" type="string"></element>
</sequence>
</complexType>
</schema>

When the service is deployed using XFire, the published WSDL is:

<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions targetNamespace="http://mycompany.com/myService" xmlns:tns="http://mycompany.com/myService" xmlns:wsdlsoap="http://schemas.xmlsoap.org/wsdl/soap/" xmlns:soap12="http://www.w3.org/2003/05/soap-envelope" xmlns:ns1="http://mycompany.com/beans" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:soapenc11="http://schemas.xmlsoap.org/soap/encoding/" xmlns:soapenc12="http://www.w3.org/2003/05/soap-encoding" xmlns:soap11="http://schemas.xmlsoap.org/soap/envelope/" xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/">

</sequence>
</complexType>
</schema>

</xsd:element>
<xsd:element name="doSomethingResponse">

<xsd:sequence>

</xsd:sequence>
</xsd:complexType>
</xsd:element>
</xsd:schema>
</wsdl:types>

</wsdl:message>

</wsdl:part>
</wsdl:message>
<wsdl:portType name="MyService">
<wsdl:operation name="doSomething">
<wsdl:input name="doSomethingRequest" message="tns:doSomethingRequest">

<wsdl:output name="doSomethingResponse" message="tns:doSomethingResponse">
</wsdl:output>
</wsdl:operation>
</wsdl:portType>
<wsdl:binding name="MyServiceHttpBinding" type="tns:MyService">
<wsdlsoap:binding style="document" transport="http://schemas.xmlsoap.org/soap/http"/>
<wsdl:operation name="doSomething">
<wsdlsoap:operation soapAction=""/>
<wsdl:input name="doSomethingRequest">
<wsdlsoap:body use="literal"/>
</wsdl:input>
<wsdl:output name="doSomethingResponse">
<wsdlsoap:body use="literal"/>
</wsdl:output>
</wsdl:operation>
</wsdl:binding>
<wsdl:service name="MyService">
<wsdl:port name="MyServiceHttpPort" binding="tns:MyServiceHttpBinding">
<wsdlsoap:address location="http://localhost:8082/reprod/services/MyService"/>
</wsdl:port>
</wsdl:service>
</wsdl:definitions>

The problem is that the "doSomethingResponse" element contains a ReturnStructure element declared in the service namespace instead of the bean namespace as specified by the targetNamespace attribute of the WebResult annotation.

Thus, when the service is invoked, the response does not comply with the WSDL but with the WebResult annotation:

<soap:Envelope xmlns:soap="http://schemas.xmlsoap.org/soap/envelope/" xmlns:xsd="http://www.w3.org/2001/XMLSchema" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">
<soap:Body>
<ns1:doSomethingResponse xmlns:ns1="http://mycompany.com/myService">
<ReturnStructure xmlns="http://mycompany.com/beans">
<code>CODE</code>
<subcode>SUBCODE</subcode>
<message>MESSAGE</message>
</ReturnStructure>
</ns1:doSomethingResponse>
</soap:Body>
</soap:Envelope>

This response is not valid regarding the WSDL ! The ReturnStructure should be ns1:ReturnStructure !

For information, the call do not fail using an XFire client (generated one or Spring remoting one) but it fails with any other client (I actually tried with Axis2).
