Segue um exemplo de código que acredito que será grande ajuda. Esta aplicação apenas escreve "Hello World!" na tela.

[code]
import javax.microedition.lcdui.Command;
import javax.microedition.lcdui.CommandListener;
import javax.microedition.lcdui.Display;
import javax.microedition.lcdui.Displayable;
import javax.microedition.lcdui.Form;
import javax.microedition.midlet.MIDlet;
import javax.microedition.midlet.MIDletStateChangeException;

/**
* This class is used to test basic execution of MIDLet HelloWorld.
*
* @author Alcides Flach
*
* @see javax.microedition.midlet.MIDlet
*/
public class HelloWorld extends MIDlet implements CommandListener {

private Display display;

private Form form;

private Command exit;

/**
* Create an instance of the MIDlet HelloWorld.
*/
public HelloWorld() {
// call the super class constructor
super();

// create a command to finish the application
exit = new Command("EXIT", Command.EXIT, 1);

// create a form object
form = new Form("J2ME Testing");

// append the messege
form.append("Hello World!");

// add the command
form.addCommand(exit);

// set the form to listen the events
form.setCommandListener(this);
}

protected void startApp() throws MIDletStateChangeException {
// get the display instace of this MIDlet
display = Display.getDisplay(this);

// set the form object visible on the display
display.setCurrent(form);
}

public void commandAction(Command c, Displayable d) {
// verify if the command event is the exit command
if (c == exit) {
try {

// signals the MIDlet to terminate and enter the Destroyed state
destroyApp(false);
} catch (MIDletStateChangeException e) {
e.printStackTrace();
}

// notify the application management software that it has entered
// into the Destroyed state
notifyDestroyed();
}
}

protected void pauseApp() {
}

protected void destroyApp(boolean arg0) throws MIDletStateChangeException {
}
}
[/code]
