InvocationTargetException

[Alicia Sánchez-Mora <al...@gmail.com>]

 Hello,

I am developig a web service in Java. I use axis 1.4 and tomcat 5.5. From
the Client (Client.java) side I have to call some services in the class (
SDMInterfaceImpl.java). All was working correctly but now I have to add a
GUI.  Every time I call I service in a graphical window should appear a
message. When I add to my application the new code to run the GUI I have the
following error in the client side:


 Exception in thread "main" AxisFault
 faultCode: {http://schemas.xmlsoap.org/soap/envelope/}Server.userException
<http://schemas.xmlsoap.org/soap/envelope/%7DServer.userException>

I attach here the service and the client code too. Could someone tell me
where the error comes from? And is it correct the way I create the GUI?

 package  org.ambientnetworks.sd_sde;
import java.awt.*;
import java.awt.event.*;

public class SDMInterfaceImpl  extends Thread implements SDMInterface{

private String hit =  "hit";
private String dummy_result = "ok";
private int result;
private int puzzle;
private List listOptions;

private static SDMInterfaceImpl instance;
private Frame f;
private TextField txtResults;



//public SDMInterfaceImpl() {
 public void init() {
          //init the GUI

      f = new Frame();
      txtResults = new TextField();
      listOptions = new List();
      f.add(listOptions);
      f.pack();
      f.setVisible(true);
  }

 public static SDMInterfaceImpl getInstance () {
      if(instance == null) {
         instance = new SDMInterfaceImpl ();
      }
      return instance;
   }

public String reqConn(String src, String dst){


    final String sourceHIT = src;
    final String destinationHIT = dst;
    new Thread (){

        public void run (){
            try {
                if (sourceHIT.equals(hit)) {
                    String res =  "ok";
                    result = new Integer (1);
                    puzzle =1;
                }

                else {
                    String res = "notOK"
                    result= new Integer (0);
                    puzzle = 10;
                }

            init();
            listOptions.addItem("reqConn");

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



    }.start();

    return dummy_result;
}
}
