Hi
Thank you for reading my post.
here i have web service with a method named hello, this method need an
String as parameter.
Service source code:



 package servletws;

   import javax.annotation.Resource;
   import javax.jws.WebService;
   import javax.xml.ws.WebServiceContext;

   @WebService
   public class HelloServlet {
       @Resource WebServiceContext wsContext;

       public String hello(String msg) {
           return "Servlet WS: " + wsContext.getUserPrincipal()
           + ": " + msg;
       }
   }





and now I want to invoke that service, here is my code that i want to
use to invoke that service along with my questions regarding it.


import java.net.MalformedURLException;
import java.net.URL;
import javax.xml.namespace.QName;
import javax.xml.rpc.Service;
import javax.xml.rpc.ServiceException;
import javax.xml.rpc.ServiceFactory;


.....

String wsdlURL = "https://server8181/ws_ssl_del/HelloServletService?wsdl";
String namespace = "http://servletws/";
String serviceName = "HelloServletService";

QName serviceQN = new QName(namespace, serviceName);
        ServiceFactory serviceFactory = null;
        try {
            serviceFactory = ServiceFactory.newInstance();
        } catch (ServiceException ex) {
            ex.printStackTrace();
        }
        try {
            /* The "new URL(wsdlURL)" parameter is optional */
            Service service = serviceFactory.createService(new
URL(wsdlURL), serviceQN);
            //what should i do now?
        } catch (MalformedURLException ex) {
            ex.printStackTrace();
        } catch (ServiceException ex) {
            ex.printStackTrace();
        }

.....


questions :
- Is that mechanism of calling web service is correct? As you can see I
have some jax-rpc import and some jax-ws import, I want just to use
jax-ws, is it do-able to use only jax-ws?
- As you see my web service method (hello) need an String parameter,
how i can pass its parameter when i want to have DDI ?

Thanks, pleas reply with some sample code snippet if you can.
