more grief with WSIF and complex types

Here's my code

 

Service serviceWsdl = WSIFUtils.selectService(def,
"http://ws.cdyne.com", "Zip2Geo");

                                    

                                                                        

WSIFService service = factory.getService(wsdl, "http://ws.cdyne.com",
"Zip2Geo", "http://ws.cdyne.com", "Zip2GeoSoap");

                                    

service.mapType(new QName("http://ws.cdyne.com", "LatLongReturn"),

                         Class.forName("com.cdyne.ws.LatLongReturn"));

                                    

WSIFPort port = service.getPort();

                                    

WSIFOperation op = port.createOperation(opName);

                                    

WSIFMessage input = op.createInputMessage();

input.setObjectPart("zipcode", "M201EF");

input.setObjectPart("LicenseKey", "");

                    

WSIFMessage output = op.createOutputMessage();

WSIFMessage fault = op.createFaultMessage();

                                    

op.executeRequestResponseOperation(input, output, fault);

 

All I get is
