What's involved in converting JPanel to JScrollPane?

Question

I've build my app and now I realised that I need scrolling functionality on my JPanel. What's involved in converting JPanel to JScrollPane ? Is this what I need to do or is there another way to do it ? I found couple of examples of JScrollPane on sun site but for some reason they don't work...

Answer 1

no none of these works for me ... maybe I have something wrong in my code ?
this is my code:
public ApplicationFrame()
final int DEFAULT_FRAME_WIDTH = 450;
final int DEFAULT_FRAME_HIGHT = 450;
setSize(DEFAULT_FRAME_WIDTH, DEFAULT_FRAME_HIGHT);
Container contentPane = getContentPane();
contentPane.setLayout(new BorderLayout());
//Init of top/help panel
          myHelpPanel = new HelpPanel();
          contentPane.add(myHelpPanel, "North");
          //init design area and add it to the container
          myDesignArea = new DesignCanvas(this);
          JScrollPane myScrollPane = new JScrollPane();
          myScrollPane.getViewport().add(myDesignArea);
          //drow canvas border.
          Border compound = BorderFactory.createCompoundBorder(BorderFactory.createEmptyBorder(5,15,15,15), BorderFactory.createLineBorder(Color.black));
          myScrollPane.setBorder(compound);
          contentPane.add(myScrollPane, BorderLayout.CENTER);
          //init tool bar and add it to the container
          DesignToolBar myTools = new DesignToolBar(myDesignArea, myHelpPanel);
          contentPane.add(myTools, "South");
          //init of menu bar and add it to the container
          JMenuBar menuBar = new JMenuBar();
          setJMenuBar(menuBar);
          //create menu item listener
          MenuListener menuItemListener = new MenuListener();
          //create file menu items and add them to the menu bar
          JMenu fileMenu = new JMenu("File");
