I created a web service that adds two integers and tried to consume it from a mobile device using WSA but it just hanged and did not work the code is as follows:

package additionserviceservice;

import client.AdditionService;
import client.AdditionService_Stub;
import java.rmi.RemoteException;
import javax.microedition.lcdui.*;

import javax.microedition.midlet.*;

public class MobileMidlet extends MIDlet implements CommandListener {
    private Display d;
    private Command okCommand;
    TextField f = new TextField("Integer 1", null, 20, TextField.ANY);
    TextField f2 = new TextField("Integer 2", null, 20, TextField.ANY);


    public void startApp() {
    
        try {
            d = Display.getDisplay(this);
           

            
            Form f1 = new Form("Consuming Addition Service");

            
            f1.append(f);
            f1.append(f2);
            f1.addCommand(getOkCommand());
            f1.setCommandListener(this);
            
            d.setCurrent(f1);


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

    

       public Command getOkCommand() {
        if (okCommand == null) {
            // write pre-init user code here
            okCommand = new Command("Ok", Command.OK, 0);
            // write post-init user code here
        }
        return okCommand;
    }

    public void pauseApp() {
    }

    public void destroyApp(boolean unconditional) {
    }
    public void commandAction(Command c, Displayable d)
    {
        try{
           
        AdditionServiceService service = new AdditionServiceService_Stub();
        char ch[] = new char[5];
        char ch2[] = new char[4];
        int n = f.getChars(ch);
        int n1 = f2.getChars(ch2);
        String s1 = "" + ch[0] + ch[1];
        String s2 = "" + ch2[0] +ch2[1];
        int result =  service.Add(Integer.parseInt(s1), Integer.parseInt(s2));

        Alert a = new Alert("Results of WebService");
        a.setString("" + result);
        Display.getDisplay(this).setCurrent(a);
       
        }
        catch(Exception ex){
            
        }
       
    }
}
