duplicate attributes in SOAP message (WSDL2Java)

[Mithun Sheshagiri]

I am using the WSDL2Java tool to generate skeleton and stubs from a WSDL 
file. I have described the following complex type in the WSDL file:

<xsd:complexType name="ItemListType">
  <xsd:sequence>
   <xsd:element name="member" minOccurs="0" maxOccurs="unbounded"
                         use="required">
    <xsd:complexType>
     <xsd:attribute ref="rdf:resource" type="xsd:string" 
form="unqualified"/>
    </xsd:complexType>
   </xsd:element>
  </xsd:sequence>
  <xsd:attribute ref="rdf:ID" type="xsd:string" form="qualified"/>
</xsd:complexType>

WSDL2Java generates classes that correspond to ItemListType and 
ItemListType_member.

I am trying to send an ItemListType type element with two member 
elements with different attributes resource="one" and resource="two". To 
set the resource value, I am using the setResource method in the 
ItemListType_member class. The following SOAP message is generated when 
I invoke the service from the client:

<?xml version="1.0" encoding="UTF-8"?>
<soapenv:Envelope 
xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/"; 
xmlns:xsd="http://www.w3.org/2001/XMLSchema"; 
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance";>
 <soapenv:Body>
  <ns1:ItemLookUpResponse 
soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; 
xmlns:ns1="Provider">
   <return href="#id0"/>
  </ns1:ItemLookUpResponse>
  <multiRef id="id0" soapenc:root="0" 
soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; 
xsi:type="ns2:ItemListType" ns3:ID="trial" 
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"; 
xmlns:ns2="http://stuff/IProvider.xsd"; 
xmlns:ns3="http://www.w3.org/1999/02/22-rdf-syntax-ns#";>
   <member href="#id1"/>
   <member href="#id2"/>
  </multiRef>
  <multiRef id="id2" soapenc:root="0" 
soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; 
resource="two" xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"/>

  <multiRef id="id1" soapenc:root="0" 
soapenv:encodingStyle="http://schemas.xmlsoap.org/soap/encoding/"; 
resource="two" resource="one" 
xmlns:soapenc="http://schemas.xmlsoap.org/soap/encoding/"/>
 </soapenv:Body>
</soapenv:Envelope>

If you look at the muliRef with id="id2", you'll see the attribute 
resource is repeated. As a result, I get a exception while parsing the 
file at the client end. Is this a bug?

Thanks!
