destroy a midlet?

How to destroy a midlet from a form not by extending midlet..?


I used code like this by Extending form

if (c == cmdExit) {
        		 mailMIDlet.notifyDestroyed();
                          }
and
if (c == cmdExit) {
        		 mailMIDlet.exitMIDlet();
                          }

In midlet

  public void exitMIDlet() {
		 destroyApp(false);
	        notifyDestroyed();
	    }

Error i'm getting is

java.lang.NullPointerException
at com.testcommand.TheFormScreen.commandAction(+12)
at javax.microedition.lcdui.Display$DisplayAccessor.commandAction(+282)
at javax.microedition.lcdui.Display$DisplayManagerImpl.commandAction(+10)

at com.sun.midp.lcdui.DefaultEventHandler$QueuedEventHandler.handleVmEvent(+186)
at com.sun.midp.lcdui.DefaultEventHandler$QueuedEventHandler.run(+57)

I know its simple but i'm not able to destroy the midlet

You need to pass a reference to the MIDlet to the Form's constructor, assign it to an instance field, and call exitMIDlet() on that reference.

Just declaring a MIDlet variable named mailMIDlet doesn't automagically assign the variable to the desired reference.

thanks for your reply

I tried what you said

In MIDlet

Display.getDisplay(this).setCurrent(  new TheEditPosition( "FormScreen" , mainPage) );

In form 'TheEditPosition' constructor

  public TheEditPosition(String title, EditMIDlet mainPage) {
        super(title);
        this.MidletPage = mainPage;
        this.addCommand(exitCommand);
        this.setCommandListener(this);
    }

I got this error.

java.lang.NullPointerException
Generic/midp2: at de.enough.polish.sample.TheEditPosition.commandAction(+12)
Unable to translate stacktrace: Unable to start the "jad"-decompiler: [java.io.IOException: Cannot run program "jad.exe": CreateProcess error=2, The system cannot find the file specified]. jad is available from http://www.kpdus.com/jad.html.
