Hi,

  Added , similar problem.
  Please explain again , I am deploying a simple Hello Web service to
jboss-4.0.4-GA server with bundled in the Netbean 5.5 IDE.

  Deployment of webservice in the JBoss is ok , when i do
http://localhost:8080/HelloWebService/HelloWS?wsdl , i can see the
wsdl format.
  And when accessing the webservice using Web Service Client in
Netbean , i can access the web service method without any error.

  My problem is the when i tried to access the web service in normal
java class for example below:
  Anyone have any ideas or suggestion , please email it to me , thanx

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

public class TestWebService {

    /** Creates a new instance of TestWebService */
    public static void main(String [] args){

     try{

         String wsdlURL = "http://cxrus020:8080/HelloWebService/
HelloWS?wsdl";
         String namespace = "urn:HelloWS/wsdl";
         String serviceName = "HelloWS";
         QName serviceQN = new QName(namespace, serviceName);

         ServiceFactory serviceFactory = ServiceFactory.newInstance();
         Service service = serviceFactory.createService(new
URL(wsdlURL), serviceQN);
         QName portQname = new QName(namespace, "HelloWSSEIPort");

         Call call = service.createCall(portQname);
         call.setPortTypeName(portQname);
         call.setProperty(Call.ENCODINGSTYLE_URI_PROPERTY, "");
         QName requestQname = new QName(namespace, "greet");
         call.addParameter("String_1", requestQname,
javax.xml.rpc.ParameterMode.IN);
         call.setReturnType(requestQname);
         String ret = (String) call.invoke(new Object[]{"joshua
tat"});
         System.out.println("ret:" + ret);

        }catch(Exception ex){
            ex.printStackTrace();
        }

}

Hi all , I need to call method from webservice that I have created.
The webservice is deployed in jboss 4.0.4 and the webservice is simple
Hello test.

However , when i tried to call method , it gaveerrorbelow:

I am new in webservice . Anyone have any ideas or suggestion is much
appreciated. Thanks

A few things stand out:

1. Theerrorappears to come while deserializing the response.
2. The following line looks odd to me:

call.setReturnType(serviceQN);

since serviceQN is neither a type nor the name of a type
3. The NPE appears to come while looking up a type in a registry of types.

Perhaps you want to call setReturnType(new
QName("'http://www.w3.org/2001/XMLSchema", "string"));
