JMenu causing image problems!

Question

I have Installed a JMenu that has an Image directly below , but! When i open the menu, The Text Value of the menu Disappears and the image has "Gray-Space"where the menu drop down was opened.
Can anyone Help and tell me why this is happening and how to Solve?
JMenuBar menuBar = new JMenuBar();
     JMenu menu = new JMenu("Setup");
     JMenuItem numOver = new JMenuItem("Input: # of Over's");
     JMenuItem numTarget = new JMenuItem("Input: Target");
public Scorebook()
       menuBar.add(menu);
       menu.add(numOver);
      menu.add(numTarget);}

Answer 1

Thanx for the pointer, wasnt sure on what i needed to add in code: heres the ClassLoader and ImageIcon
as for Setting Visability, i dont think i have set it i just tried menu.setVisable(true) but it didnt like it!
ClassLoader ldr = this.getClass().getClassLoader();
     java.net.URL cbURL = ldr.getResource("cricketball.png");
     ImageIcon cBall = new ImageIcon(cbURL);
     JLabel cBallL = new JLabel(cBall);
JMenuBar menuBar = new JMenuBar();
     JMenu menu = new JMenu("Setup");
     JMenuItem numOver = new JMenuItem("Input: # of Over's");
     JMenuItem numTarget = new JMenuItem("Input: Target");
public Scorebook()
       menuBar.add(menu);
       menu.add(numOver);
       menu.add(numTarget);}
       pnl.add(CBallL);
