Problem developing application on NetBeans Platform

Hi,

I wrote a "HelloWorld" example application to demonstrate using the 
NetBeans platform, based on some instructions from this website: 
http://www.javalobby.org/java/forums/t17711 This module runs perfectly, 
creating a menu entry named HelloWorld and popping up a dialog box when 
its clicked.

Then I copied off all the HelloWorld code into another directory 
HelloWorld2 so that I could mess around in this new module HelloWorld2. 
I made changes to the code and other files as required for this new 
module. Following is the code:

manifest.mf in HelloWorld2:
Manifest-Version: 1.0
OpenIDE-Module: helloworld2/1
OpenIDE-Module-IDE-Dependencies: IDE/1 > 3.17
OpenIDE-Module-Layer: helloworld2/resources/mf-layer.xml
OpenIDE-Module-Specification-Version: 1.0

mf-layer.xml in HelloWorld2/src/helloworld2/resources:
<?xml version="1.0" encoding="UTF-8"?>
<!DOCTYPE filesystem PUBLIC "-//NetBeans//DTD Filesystem 1.1//EN" 
"http://www.netbeans.org/dtds/filesystem-1_1.dtd">
<filesystem>
<folder name="Menu">
  <folder name="HelloWorld2">
    <file name="helloworld2-actions-HelloWorldAction2.instance"/>
  </folder>   </folder>
</filesystem>

HelloWorldAction2.java in HelloWorld2/src/helloworld2/actions:
package helloworld2.actions;
import org.openide.util.HelpCtx;
import org.openide.util.actions.CallableSystemAction;
import javax.swing.JOptionPane;

public class HelloWorldAction2 extends CallableSystemAction {

  public HelpCtx getHelpCtx() {
      return HelpCtx.DEFAULT_HELP;
  }

  public String getName() {
      return "Say HelloWorld2";
  }
 
  public void performAction() {
      String msg = "Hello World 2";
      JOptionPane.showMessageDialog(null,msg);
  }
}

This module, is just not working. It will compile and bring up the gui, 
but it does not add a HelloWorld2 menu item to the gui as expected. I 
have gone over the code files again and again and can't figure out the 
problem. Please help me out if you can.

I do not want to make a module for the NetBeans IDE, I want to make an 
independent application which is based on the NetBeans platform, 
something like Minex. I want to modify the menus, toolbar and add in 
some existing modules, but I'm not sure how to do all this. Any help is 
greatly appreciated.

Thanks.

Regards,
Karan
