Hi
I have a question to a JAX-WS project using JDK 1.6.0_45
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:
Call
body0: javax.xml.ws.Holder@12d263f
body0.value: namespace.ias.webservice.schema.GetTransactionListResponseType@12a0f6c
*BOOM*

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.
After half a day of googling and trying this and tthat i'm left clueless.
Have you any ideas?
Bye
