Empezando con j2ME con MIDlet

[calichecal]

hola a todos e programado mucho en la edicion estandar J2SE de java y ahora me anime a aprender J2ME y estoy haciendo mis primeros programas para MIDlets, y no tengo idea por que el emulador no me quiere correr este pequeño programa:

Código PHP:

  package principal;
/**
 *
 * @author stivenson
 */
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;

 public class ejemploalerta extends MIDlet implements CommandListener{
      Alert alerta1,alerta2;
      Command salir,aler1,aler2;
      Displayable temp;
      Display pantalla;
      Form pantallainicial;

     public ejemploalerta(){
       //Obtengo la referencia ala pantalla del MIDlet
         pantalla=Display.getDisplay(this);
       //Creo los objetos que forman las pantallas del MIDlet
         salir=new Command("Salir",Command.EXIT,1);
         aler1=new Command("Alerta Modal",Command.SCREEN,1);
         aler2=new Command("Alerta No Modal",Command.SCREEN,1);
         //Creo la pantalla de alerta 1
         alerta1=new Alert("Alerta Modal","Esta alerta desaparecera"+" cuando pulse el boton aceptar",null,AlertType.INFO);
         alerta2=new Alert("Alerta No Modal","Esta alerta desaparecera" +"cuando pasen 5 segundos",null,AlertType.INFO);
         alerta1.setTimeout(Alert.FOREVER);
         alerta2.setTimeout(5000);
         //creo la pantalla principal del MIDlet
         pantallainicial=new Form("Programa inicial");
         //inserto objetos en la pantalla
        pantallainicial.addCommand(salir);
        pantallainicial.addCommand(aler1);
        pantallainicial.addCommand(aler2);
        pantallainicial.setCommandListener(this);
     }
    public void destroyApp(boolean unconditional){
       
    }

    public void pauseApp(){
       
    }

    public void startApp(){
       pantalla.setCurrent(pantallainicial);
    }

    public void commandAction(Command c, Displayable d) {
      if(c==salir){
       destroyApp(false);
       notifyDestroyed();
       }else if(c==aler1){
              pantalla.setCurrent(alerta1, pantallainicial);
              }else{
              pantalla.setCurrent(alerta2, pantallainicial);
              }
    }


}  
   

yo utilizo el programa: java(TM) ME platform SDK 3.0
y este automaticamente crea el .jav y todos los pasos y lo ejecuta en el emulador que trae incluido, en fin la informacion de todo el proceso que hace cuando lo compilo y ejecuto es este:
