Hide Java application in windows alt-tab menu

Question

Hi,
I got this JFrame that should be always on top but I don't won't it to show up in the windows alt-tab menu. (just like many other windows programs like winamp for instance).
setEnabled(false) hides the frame from alt-tab menu but also kills the frame...
Any ideas?
TIA

Unfortunately, according to javadoc, a JWindow can not receive focus unless
it's a child window of a visible Frame or Dialog.you can trick the JWindow into thinking it has a visible parent, so focusing is
not a problem, but this still shows up in alt-tab
import javax.swing.*;
import java.awt.*;
class Testing
  public void buildGUI()
    JWindow window = new JWindow(new JFrame(){
       public boolean isShowing(){return true;}});
    JScrollPane sp = new JScrollPane(new JTextArea("Hello World",5,10));
    window.getContentPane().add(sp,BorderLayout.NORTH);
    window.setSize(400,300);
    window.setLocationRelativeTo(null);
    window.setVisible(true);
  public static void main(String[] args)
    SwingUtilities.invokeLater(new Runnable(){
      public void run(){
        new Testing().buildGUI();
}
