Overlapping of objects...

Question

Hi,
I'm doing an application that has a JMenu on the top and a ScrollPane on the rest of the screen. The problem is that depending where I execute that, the items of the JMenu appears behind the ScrollPane, and obviously it's not useful... Yes, I'm talking about the third dimension of the screen. ScrollPane is in the front and doesn't allow to the user to see the JMenu items, when he click on each category...
Anyone can help me?
Thanks in advance

Yes, you're right, i should have provided some code... Here you have (more after the code)
import java.awt.*;
import javax.swing.*;
public class ui extends JFrame
public ui()
super("Test");
enableEvents(AWTEvent.WINDOW_EVENT_MASK);
//initialitzates all the ui
init();
this.setDefaultCloseOperation(this.EXIT_ON_CLOSE);
this.pack();
this.setExtendedState(this.MAXIMIZED_BOTH);
this.setVisible(true);
private void init()
JPanel container;
ScrollPane sp;
JMenuBar menu;
container = (JPanel)this.getContentPane();
//creates the elements to show
menu = ini_menu();
// sp = new ScrollPane();
this.setJMenuBar(menu);
container.add(sp);
private JMenuBar ini_menu()
{ //top bar menu
JMenu file;
JMenuItem open, close, exit;
JMenuBar menu;
open = new JMenuItem("Open a file");
close = new JMenuItem("Close a file");
exit = new JMenuItem("Exit application");
file = new JMenu("File");
file.add(open);
file.add(close);
file.add(exit);
menu = new JMenuBar();
menu.add(file);
return (menu);
public static void main(String agrs[])
new ui();
Please try to execute this piece of code and you will see the screen with a top bar menu running perfectly. But if you remove the double-slash from the line highlighted between /***/ and /***/, you will see that you are not able to see the item from the top bar menu.
Executing this piece of code in various machines made me realise that in old versions like 1.4.0 there's no problem, while 1.4.2 or .1.5.0 is giving me the problem.
Please help.
Thanks
