WLS 11g. Dynamic webservice client. Input is complext type. Output String.

Question

Hi,
I used Webservice annotations to generate a WS (as given in WLS documentation). I am creating a dynamic client but when I invoke the client I get error.
@WebService(name="ErrorHandlerPortType", serviceName="ErrorHandlerService")
public class ErrorHandler {
     @WebMethod()
     public String callErrorHandler(ErrorMessage message) {
          try {
               System.out.println("Producer: " + message.getProducer());
               return "Here is the descirption: '" + message.getErrorDescription() + "'";
          } catch (Exception ex) {
               ex.printStackTrace();
               return "Caught Exception";
public class ErrorMessage implements java.io.Serializable {
     private String consumer;
     private String producer;
     private String errorCode;
     private String errorDescription;
WSLD which got generated.

                    call.setTargetEndpointAddress(endpoint);
                    ErrorMessage errMsg = FormErrorMessage.getMessage("EXCEL", "PMM", "EXL123", "Trial Error Message");
                    System.out.println("Going to invoke......");
                    Object[] params = { errMsg };
                    Double result = (Double)call.invoke(params);
I am getting the error:

Please help. I have got stuck here for last couple of days.

Hi,
You can try to add this property setting in client code:
System.setProperty("javax.xml.rpc.ServiceFactory", "weblogic.wsee.jaxrpc.ServiceFactoryImpl");
Meanwhile, the line:
QName messageDatatype = new QName("java:katz.integration.esb.errorhandling.datatype");
should be:
QName messageDatatype = new QName("java:katz.integration.esb.errorhandling.datatype", "ErrogMessage"); ?
Thanks,
Kevin
