Creation of an applet JApplet in a desktop JDesktopPane

Question

how its posible to load from a jar file an applet which come from package my.package.myclass of the jar file.
next i want to put it in a JInternalFrame and put this desktop frame in a JDesktopPane.
indeed i can move the applet around with other applets in a little window!
here's the code of the desktop_panel.javapackage kevin_shell;

Answer 1

What about calling getLocation on the applet itself?
Otherwise, if you are using Swing, you can try (where "this" is the applet object):
javax.swing.SwingUtilities.getWindowAncestor(this).getLocation();
or
javax.swing.SwingUtilities.convertPointToScreen(this.getLocation(), this);
The latter should work, at least.
