Hi all experts,

I just started to try writing my first hello world J2ME app into my Oxygen XdaII phone(pocket PC). However, i kept facing "ClassFormatError" while i try to run it on O2 PDA.

Why is tat so? anyone can enlighten me?

1. We have installed Jeode 1.1 Runtime on the O2 and also J2SDK 1.5 on the PC.
2. We have followed instruction on Jeode readme to create a link to Try.jar in this way:
(18#"\Windows\evm.exe" -Djeode.evm.console.local.keep=TRUE -cp \Windows\lib\Try.jar)
3. The hello world code is as simple as below:

import javax.microedition.lcdui.*;
import javax.microedition.midlet.*;

public class Try extends MIDlet {
      Display display;
    public Try(){
            display = Display.getDisplay(this);
            Form f = new Form("Hello");
            f.append("Hello World!!!");
      public void destroyApp(boolean unconditional){
      public void startApp(){
      public void pauseApp(){
