thanks for your reply. the following is my code to invoke a web service:
//code................................................
private void sendOrder(String orderid, String message)
throws ClassNotFoundException, SQLException{
// Setup the global JAX-RPC service factory
try{
System.setProperty( "javax.xml.rpc.ServiceFactory",
"com.sun.xml.rpc.client.ServiceFactoryImpl");
// create service factory
ServiceFactory factory = ServiceFactory.newInstance();
// define qnames
String targetNamespace = "http://www.wowgao.com/exchange/server"
+ "wsdl/";
QName serviceName = new QName(targetNamespace,
"WGOrder.WGOrderBean");
QName portName = new QName(targetNamespace,
"WGOrderPort");
QName operationName = new QName("urn:WGOrder", "orderSubmit");
// create service
Service service = factory.createService(serviceName);
// create call
Call call = service.createCall();
// set port and operation name
call.setPortTypeName(portName);
call.setOperationName(operationName);
// add parameters
call.addParameter("BuyerID",
new QName("http://www.w3.org/2001/XMLSchema", "string"),
ParameterMode.IN);
call.addParameter("SellerID",
new QName("http://www.w3.org/2001/XMLSchema", "string"),
ParameterMode.IN);
call.addParameter("order",
new QName("http://www.w3.org/2001/XMLSchema", "string"),
ParameterMode.IN);
call.setReturnType(new QName( "http://www.w3.org/2001/XMLSchema","long") );
// set end point address
call.setTargetEndpointAddress("http://www.xmethods.com:9090/soap");
// invoke the remote web service
String result = (String)call.invoke(operationName, new Object[]{"123","234",message});
how do i set the com.sun.xml.rpc.client.ServiceFactor so that it know where to find the class? you said in the deployment descriptor. do you mean that whoever deploy a web app, it needs to speify this class in the deployment descriptor? i am not sure i understand what you said.
