JFrame remove taskbar Icon

Question

I have a JFrame that I minimize to the tray using:

This for showing:

Frame.this.Minimized = false;
Frame.this.setVisible(true);
systemTray.remove(systemTrayIcon);
Frame.this.setExtendedState(JFrame.NORMAL);

And this for hiding:

if (SystemTray.isSupported()) {
    systemTray.add(systemTrayIcon);
    Frame.this.setVisible(false);
    Frame.this.Minimized = true;
}
Frame.this.setExtendedState(JFrame.ICONIFIED);

However, I do NOT want to set the frame invisible.. When I set it invisible, it removes the taskbar icon which I like. Is there a way to remove the taskbar icon of the frame without setting the visibility to false?

The reason is because when I minimize my application, I can send it commands and it executes them but the second that I set its visibility to false, it stops executing any commands from an external application. All I need to do is remove the icon from the taskbar when minimized and show the icon when normal.

Any ideas?

I know this is VERY late, but I spent a good hour trying to figure this out myself. All you have to do is change your JFrame to a JWindow and you're done. I had a fairly complex JFrame and the only things I had to remove were setUndecorated() and setDefaultCloseOperation(). everything else worked just fine.
