Cannot create class in system package: help!

LornaJane asked
Last Modified: 2013-11-24
I am working on a j2me application, and I can compile, preverify and jar everything fine.  However the emulator gives this error message:

Cannot create class in system package

I think this is a general java question rather than a midlet-related one, and I really hope one of you guys can help ... Java isn't really my area of expertes!  Here's the code:

import javax.microedition.lcdui.*;
import javax.microedition.lcdui.game.*;
import javax.microedition.midlet.*;
import java.io.*;

public class hello extends MIDlet implements CommandListener
      Command exitCommand = new Command("exit", Command.EXIT, 1);
      ScreenPic screenPic;

      public hello()
            screenPic = new ScreenPic();

      protected void startApp()
            System.out.println("starting application");

      protected void pauseApp()

      protected void destroyApp(boolean b)

      public void commandAction(Command c, Displayable d)
            if(c == exitCommand) notifyDestroyed();


public class ScreenPic extends GameCanvas
      Image image;
      Byte imageData;

       public ScreenPic()
            byte[] imageData = new byte[(int)5120*5120];
            image.createImage(imageData, 0, imageData.length);
