WebParam.Mode.OUT always returns a null holder-value in response

[Tomas-Kraus]

Hi

First Jira contact ever. Hope i don't mess this up.

I've generated a webservice from a WSDL looking like this:

... <wsdl:operation name="getTransactionList"> <soap:operation style="document" soapAction="getTransactionList"/> wsdl:input <soap:body use="literal" parts="body"/> <soap:header use="literal" message="tns:getTransactionListRequest" part="header"/> </wsdl:input> wsdl:output <soap:body use="literal" parts="body"/> <soap:header use="literal" message="tns:getTransactionListResponse" part="header"/> </wsdl:output> <wsdl:fault name="fault1"> <soap:fault use="literal" name="fault1"/> </wsdl:fault> </wsdl:operation> ... <wsdl:message name="getTransactionListResponse"> <wsdl:part name="header" element="ns0:responseHeader"/> <wsdl:part name="body" element="ns0:getTransactionListResponse"/> </wsdl:message> ...

As you can see, getTransactionList returns a message with 2 components, header and body. Using wsimport this ends up like this:

@WebMethod(action = "getTransactionList") public void getTransactionList( @WebParam(name = "requestHeader", targetNamespace = "http://namespace/IAS/WebService/Schema", header = true, partName = "header") RequestHeaderType header, @WebParam(name = "getTransactionListRequest", targetNamespace = "http://namespace/IAS/WebService/Schema", partName = "body") GetTransactionListRequestType body, @WebParam(name = "responseHeader", targetNamespace = "http://namespace/IAS/WebService/Schema", header = true, mode = WebParam.Mode.OUT, partName = "header") Holder<ResponseHeaderType> header0, @WebParam(name = "getTransactionListResponse", targetNamespace = "http://namespace/IAS/WebService/Schema", mode = WebParam.Mode.OUT, partName = "body") Holder<GetTransactionListResponseType> body0) throws ErrorInfo ;

The two return values are annoted as WebParam.Mode.OUT.

Now i've written a short test method

public static void main(final String[] args) throws Exception { try { IASService _s = new IASService(new URL("http://127.0.0.1/WodisScratch/IAServiceEndpoint?wsdl"), new QName( "http://namespace/IAS/WebService/WDSL/concrete", "IAS_Service")); RequestHeaderType header = new RequestHeaderType(); GetTransactionListRequestType body = new GetTransactionListRequestType(); Holder<ResponseHeaderType> header0 = new Holder<ResponseHeaderType>(new ResponseHeaderType()); Holder<GetTransactionListResponseType> body0 = new Holder<GetTransactionListResponseType>(new GetTransactionListResponseType()); System.out.println("Call"); System.out.println("body0: " + body0); System.out.println("body0.value: " + body0.value);

System.out.println("BOOM"); _s.getIAServiceEndpoint().getTransactionList(header, body, header0, body0); System.out.println("Never seeing this");

for (Transaction _t : body0.value.getTransaction())

{ System.out.println(_t.getTransactionId()); }

} catch (ErrorInfo e)

{ e.printStackTrace(); }

}

Output:

The implementation looks like this:

public void getTransactionList(final RequestHeaderType header, final GetTransactionListRequestType body, final Holder<ResponseHeaderType> header0, final Holder<GetTransactionListResponseType> body0) throws ErrorInfo { System.out.println("Start"); System.out.println("body0: " + body0); System.out.println("body0.value: " + body0.value); ...

Output: Start body0: javax.xml.ws.Holder@1af8502 body0.value: null

Somewhere between API call and implementation the Holder-value ist lost, and replaced by another one with a null-value.
