J2ME Programming Issue on VM: 1.5.0_06

Hi guys, I have tried to run the following codes (compiled with no
problem) from an IDE (JCreator LE) and i got the following exceptions.

However i managed to run it on the sun java windows tool kit's
KToolbar..

SOURCE CODE
------------
import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;

public class TinyMIDlet extends MIDlet implements CommandListener{

    String s = "Hello \"cruel\" world!";
    private Command quit;
    private Display ourDisplay;
    private Form ourForm;
    private TextField ourField;

    public TinyMIDlet(){
        ourDisplay = Display.getDisplay(this);
        quit = new Command("quit", Command.SCREEN, 2);
    }

    public void startApp(){
        ourForm = new Form ("our first!");
        ourField= new TextField ("J2ME App", s, 256, 0);

        ourForm.append(ourField);
        ourForm.addCommand(quit);
        ourForm.setCommandListener(this);
        ourDisplay.setCurrent(ourForm);
    }

    public void pauseApp(){
    }

    public void destroyApp(boolean unconditional){
    }

    public void commandAction(Command c, Displayable s){
        if (c == quit){
            destroyApp(false);
            notifyDestroyed();
        }
    }

    public static void main(String[] a){
        TinyMIDlet hfj2me = new TinyMIDlet();
    }

}

Do i have to install any dll files before i can run this from my IDE?
Please advice.

Thanks (a lot) in advance.
