WSDL for web method with parameters from different namespaces

Question

I'm trying to create a web service that exposes a method that accepts a JAXB XML object and a timestamp as parameters and returns another JAXB XML object. I've tried to follow the contract-first method by creating the schema and WSDLs first. I've created the schemas for the XML and deployed them on a web server and I've written the following WSDL:
<?xml version="1.0" encoding="UTF-8"?>
<wsdl:definitions xmlns:soap="http://schemas.xmlsoap.org/wsdl/soap/"
     xmlns:tns="http://bar.org"
     xmlns:wsdl="http://schemas.xmlsoap.org/wsdl/"
     xmlns:xsd="http://www.w3.org/2001/XMLSchema" name="MyWebService"
     xmlns:ns0="http://foo.org/Transaction"
     xmlns:ns1="http://bar.org/TransactionResponse"
     targetNamespace="http://bar.org">
     <!-- T Y P E S -->
     <wsdl:types>
          <xsd:schema targetNamespace="http://bar.org"
              xmlns:ns0="http://foo.org/Transaction"
              xmlns:ns1="http://bar.org/TransactionResponse"
              xmlns="http://bar.org">
               <xsd:import namespace="http://foo.org/Transaction" schemaLocation="http://myHost/schemas/Transaction.xsd"/>
               <xsd:import namespace="http://bar.org/TransactionResponse" schemaLocation="http://myHost/schemas/TransactionResponse.xsd"/>
               <xsd:element name="ProcessTransactionRequest">
                   <xsd:complexType>
                       <xsd:sequence>
                           <xsd:element ref="ns0:Transaction"/>
                           <xsd:element name="TransactionTime" type="xsd:dateTime"/>
                       </xsd:sequence>
                   </xsd:complexType>
               </xsd:element>
          </xsd:schema>
     </wsdl:types>
     <!-- M E S S A G E S -->
     <wsdl:message name="ProcessTransactionRequest">
          <wsdl:part element="tns:ProcessTransactionRequest" name="parameters" />
     </wsdl:message>
     <wsdl:message name="ProcessTransactionResponse">
          <wsdl:part element="ns1:TransactionResponse" name="parameters" />
     </wsdl:message>
     <!-- P O R T   T Y P E -->
     <wsdl:portType name="MyWebServicePortType">
          <wsdl:operation name="ProcessTransaction">
               <wsdl:input message="tns:ProcessTransactionRequest" />
               <wsdl:output message="tns:ProcessTransactionResponse" />
          </wsdl:operation>
     </wsdl:portType>
     <!-- B I N D I N G -->
     <wsdl:binding name="MyWebServiceSOAP" type="tns:MyWebServicePortType">
          <soap:binding style="document"
               transport="http://schemas.xmlsoap.org/soap/http" />
          <wsdl:operation name="ProcessTransaction">
               <soap:operation soapAction=""/>
               <wsdl:input>
                    <soap:body use="literal"/>
               </wsdl:input>
               <wsdl:output>
                    <soap:body use="literal"/>
               </wsdl:output>
          </wsdl:operation>
     </wsdl:binding>
     <!-- S E R V I C E -->
     <wsdl:service name="MyWebService">
          <wsdl:port binding="tns:MyWebServiceSOAP" name="MyWebServiceSOAP">
               <soap:address location="http://www.example.org/"/>
          </wsdl:port>
     </wsdl:service>
</wsdl:definitions>However when I run the WsImport tool bundled with JAX-WS RI 2.1.1, I get the following interface:
public interface MyWebServicePortType {
     * @param parameters
     * @return
     *     returns org.bar.transactionresponse.TransactionResponse
    @WebMethod(operationName = "ProcessTransaction")
    @WebResult(name = "TransactionResponse", targetNamespace = "http://bar.org/TransactionResponse", partName = "parameters")
    public TransactionResponse processTransaction(
        @WebParam(name = "ProcessTransactionRequest", targetNamespace = "http://bar.org", partName = "parameters")
        ProcessTransactionRequest parameters);
}Which is workable, but I was wondering how to modify the WSDL to get a web method signature similar to:
public TransactionResponse processTransaction(
        @WebParam(name = "Transaction", targetNamespace = "http://foo.org/Transaction", partName = "transaction")
        Transaction transaction,
        @WebParam(name = "TransactionTime", targetNamespace = "http://bar.org", partName = "transactionTime")
        XMLGregorianCalendar transactionTime);With two parameters in the parameter list instead of one. Is there a way to do this?

Answer 1

Try changing the <xsd:element name="ProcessTransactionRequest"> element name to: <xsd:element name="ProcessTransaction"> and update the reference to it in the <wsdl:message name="ProcessTransactionRequest"> message.
In order to use wrapper style, your WSDL needs to have the following characteristics:
1) The operation's input and output messages (if present) each contain a single part
2) The input message part refers to a global element declaration whose localname is equal to the operation name
3) The output message refers to a global element declaration
4) The elements referred to by the input and output message parts (henceforth referred to as wrapper elements) are both complex types defined using the xsd:sequence compositor
5 The wrapper elements only contain child elements, they must not contain other structures such as wildcards...
