It's very straightforward. Just add the panel to the ScrollPane the same as you would with any other container. Here's a link to the API:
http://java.sun.com/j2se/1.3/docs/api/java/awt/ScrollPane.html


ScrollPane pane = new JScrollPane();
Panel panel = new Panel();
pane.add(panel);

Kajol,
Here is one way to do what you are asking:

import java.awt.*;
import java.awt.event.*;
public class Test extends Frame
{
MyPanel mp ;
Test()
{
super("this is the scroll test");
add( new Label("here are the labels:"), BorderLayout.NORTH);
mp = new MyPanel();
ScrollPane sp = new ScrollPane();
sp.add(mp);
add(sp, BorderLayout.SOUTH);
pack();
}
public static void main(String args[])
{
Test theApp = new Test();
theApp.addWindowListener(new WindowAdapter(){
public void windowClosing(WindowEvent we){
System.exit(0);
}
});
theApp.setSize(320, 240);
theApp.show();
}
}
class MyPanel extends Panel
{
Label theLabels[];
MyPanel()
{
theLabels = new Label[10];
setLayout(new GridLayout(theLabels.length, 1));
for(int i = 0; i < theLabels.length; i++)
{
theLabels[i] = new Label("I am label " + (i + 1));
add(theLabels[i]);
}
setSize(100, 100);
}
}

This code displays labels in a scrolling panel.
Hope this helps.

Why don't you post the code you are using? I tested the following and it works just fine:

import java.awt.*;
public class Scroller {
  public static void main(String[] args) {
    Button test = new Button("Really long button to make the panel scroll.");
    Panel panel = new Panel();
    panel.add(test);
    ScrollPane pane = new ScrollPane(ScrollPane.SCROLLBARS_ALWAYS);
    pane.add(panel);
    Frame frame = new Frame();
    frame.add(pane);
    frame.setLayout(new FlowLayout());
    frame.resize(300, 300);
    frame.show();
  }
}
