First look for obvious problems, such as: Where do you add the JMenuBar to the JFrame? JFrame has a method for this, setJMenuBar(...), and I don't see it being called anywhere.

I suggest that you go through the Java Swing menus tutorials as this is all well explained there.

hey.. thnx alottt.. it worked.. cn u plzz tell me wat does setJMenuBar(mb) mean??
