Exit Command doesn't work

Question

Guys, I've put a few hours researching the web for code examples on how to program the Exit button on a J2ME app. It didn't help me finding out why my Exit simply doesn't work. It must be something trivial that I'm just not aware of. I would really appreciate your help analyzing the following code.
Regards,
Filipe
public class BiblioMIDlet extends MIDlet implements CommandListener {
     private Display display;
     private Form gui;
     private static Command renewCommand, exitCommand;
     public BiblioMIDlet() {
          renewCommand = new Command("Renew", Command.ITEM, 1);
          exitCommand = new Command("Exit", Command.EXIT, 1);
          gui = new Form("Biblio");
          display = Display.getDisplay(this);
     protected void startApp() throws MIDletStateChangeException {
          this.showLoginForm();
     private void showLoginForm() {
          TextField user = new TextField("User", null, 9, TextField.NUMERIC);
          TextField password = new TextField("Password", null, 4, TextField.PASSWORD | TextField.NUMERIC);
          gui.append(user);
          gui.append(password);
          gui.addCommand(renewCommand);
          gui.addCommand(exitCommand);
          display.setCurrent(gui);
     protected void pauseApp() {     }
     public void commandAction(Command c, Displayable s) {
          if (c == exitCommand) {
               destroyApp(false);
               notifyDestroyed();
     protected void destroyApp(boolean arg0) {      }
}

Hai
I think u missed to add the commandListener in your code "gui.setCommandListener(this)"
public class BiblioMIDlet extends MIDlet implements CommandListener {
     private Display display;
     private Form gui;
     Command renewCommand, exitCommand;
     public BiblioMIDlet() {
          renewCommand = new Command("Renew", Command.ITEM, 1);
          exitCommand = new Command("Exit", Command.EXIT, 1);
          gui = new Form("Biblio");
          display = Display.getDisplay(this);
     protected void startApp() throws MIDletStateChangeException {
          this.showLoginForm();
     private void showLoginForm() {
          TextField user = new TextField("User", null, 9, TextField.NUMERIC);
          TextField password = new TextField("Password", null, 4, TextField.PASSWORD | TextField.NUMERIC);
          gui.append(user);
          gui.append(password);
          gui.addCommand(renewCommand);
          gui.addCommand(exitCommand);
/* u missed this line of code in your program*/
          gui.setCommandListener(this);
/* End */
          display.setCurrent(gui);
     protected void pauseApp() {     }
     public void commandAction(Command c, Displayable s) {
          if (c == exitCommand) {
               destroyApp(false);
{ notifyDestroyed();
     protected void destroyApp(boolean arg0)      }
