Hi...

Am getting the following exception when trying to invoke a webservice from a dynamic client using WSDL...

javax.xml.rpc.JAXRPCException: failed to invoke operation 'sayHello' due to an error in the soap layer (SAAJ); nested exception is: Message[ failed to serialize interface javax.xml.soap.SOAPElementweblogic.xml.schema.binding.SerializationException: mapping lookup failure. class=interface javax.xml.s

My client code is given below....

System.setProperty("javax.xml.soap.MessageFactory", "weblogic.webservice.core.soap.MessageFactoryImpl");          
System.setProperty( "javax.xml.rpc.ServiceFactory", "weblogic.webservice.core.rpc.ServiceFactoryImpl");
                                
ServiceFactory serviceFactory = ServiceFactory.newInstance();
URL wsdlURL = new URL("http://localhost:7001/Services/Hello/Hello.jws?WSDL");
String targetNameSpace = "http://www.openuri.org/";
            
QName serviceName = new QName(targetNameSpace, "Hello");
QName portName = new QName(targetNameSpace, "HelloSoap");
QName operationName = new QName("","sayHello");
                
Service service = serviceFactory.createService(wsdlURL, serviceName);
Call call = service.createCall(portName, operationName);
            
Object[] objArr = {"World"};
String ret = (String) call.invoke(objArr);
System.out.println("Return is: "+ret);

Could anyone tell as to what is causing the problem???
