Viewing menu items in menubars

I have created a methods to create a menubar.  When I put it on the frame I can see the menu titiles, but when I click on the menus it does not drop down to display the menu items for the menus.  I sort of followed a tutorial that I saw on the sun website but it has not helped me.  Any help would be nice. Also I am trying to upload xml files in my jframe so if anyone can give me some directions on what would be the best way to go about it that would help as well.  Thanks in advance.  Here is my code:

public JMenuBar xmlMenu() {
            
            JMenuBar menuBar;
            JMenu file, operation;
            JMenuItem open, save, exit, query;
            
            menuBar = new JMenuBar();
            
            file = new JMenu("File");
            file.setMnemonic(KeyEvent.VK_A);
            file.getAccessibleContext().setAccessibleDescription(
                "The only menu in this program that has menu items");
            menuBar.add(file);
            
            open = new JMenuItem("open");
            open.setAccelerator(KeyStroke.getKeyStroke(
                KeyEvent.VK_1, ActionEvent.ALT_MASK));
        open.getAccessibleContext().setAccessibleDescription(
                "This doesn't really do anything");
            open.addActionListener(this);
            file.add(open);
            
            save = new JMenuItem("save");
            save.addActionListener(this);
            file.add(save);
            exit = new JMenuItem("exit");
            exit.addActionListener(this);
            file.add(exit);
            
            operation = new JMenu("Operations");
            menuBar.add(operation);
            
            query = new JMenuItem("Query");
            operation.add(query);
            
            return menuBar;
            
      }//end JMenuBar

public JMenuBar xmlMenu() {
         
          JMenuBar menuBar;
          JMenu file, operation;
          JMenuItem open, save, exit, query;
         
          menuBar = new JMenuBar();
         
          file = new JMenu("File");
          file.setMnemonic(KeyEvent.VK_A);
          file.getAccessibleContext().setAccessibleDescription(
                "The only menu in this program that has menu items");
         
         
          open = new JMenuItem("open");
          open.setAccelerator(KeyStroke.getKeyStroke(
                KeyEvent.VK_1, ActionEvent.ALT_MASK));
          open.getAccessibleContext().setAccessibleDescription(
                "This doesn't really do anything");
          open.addActionListener(this);
          file.add(open);
         
          save = new JMenuItem("save");
          save.addActionListener(this);
          file.add(save);

          exit = new JMenuItem("exit");
          exit.addActionListener(this);

          operation = new JMenu("Operations");
         
         
          query = new JMenuItem("Query");

         menuBar.add(file);
          menuBar.add(operation);

I seem to have found out my problem.  In my code I was mixing awt components with swing components.  I was using Panel in stead of JPanel.  Once I changes Panel to JPanel that resolved my problem.  Thanks for your help.
