ScrollBars not showing up for the JPanel [urgent]

No you don't need to implement anything.

Simply add the components you want onto the JPanel and then

call

scrollPane.setViewPort(panel);

Alternatively you can choose to add the panel to the JScrollPane when you construct it.

scrollPane = new JScrollPane(panel) or

scrollPane = new JScrollPane(panel , vsbPolicy, hsbPolicy)

hsb/vsb = int hori/ver scrollbar policy

and can take values

ScrollPaneConstants.HORIZONTAL_SCROLLBAR_AS_NEEDED

ScrollPaneConstants.HORIZONTAL_SCROLLBAR_ALWAYS

(Similarly with VERTICAL)

Thank you all for your replies.I added the scroll bar policy.The scroll bars are showing up but the components inside the Panel are not moving.I want the components to move when i am scrolling.Here is my code.In the code SeriesDescPanel, SeriesDescMapPanel are sub classes of JPanel.I am using null layout to add the components to these panels.

public class MainWindow extends JFrame implements TreeExpansionListener

{

public MainWindow()

I am sorry.Yes, only part of the JPanel is visible and the components in that part are only showing up.When i drag the split pane's border down then only i could see the total JPanel and all the components in it.My manager want it like, with out dragging the border itself the components should scroll just like the rows in a JTable scrolls . I am sending the JPanel subclass code.

public class SeriesDescMapPanel extends JPanel

public SeriesDescMapPanel()
