JMenu and JTabbedPane questions

Question

Hello I got 2 questions :
1) Is it possible to change the icon of JMenu when the mouse cursor is on it ? setRolloverIcon function doesnt work in this case, like it does for the JButton.
2) When I create my application I got 1 JTabbedPane object visible. Now, every time I click a selected JMenuItem, I wanna add another JTabbedPane object to the window. So in the class MyMenu I got this code in actionListener:
if(arg.equals("menu1")) {
     JTabbedPane tabbedPane = new JTabbedPane();
     tabbedPane.addTab("tab", null, null, "nothing");
     frame.getContentPane().add(tabbedPane);
The problem is that it doesnt appear on the window, but instead when I resize it, there is a vertical line in the place where the right "edge" of the old window was.
Can anyone tell me what do I do wrong ?
Thx in advance.

Actually I dont know but the simpliest way seems to be subclassing the menu Item, and listen for mouse events. When you learn a better way to do it you can change your code :)
Java always allowed me to do such tricks :)
