Adding JButton, JTextField to scroll pane...

Question

I have developed an appln in which I have added JPanel to JFrame.
To this JPanel I m adding JButton & JTextField. But the JButton & JTextField are increasing dynamically in my appln[according to DBMS query]. So I wanted to use scrolpane or something like so that the window can be scrolled vertically to view all the components[JButton & JTextField]. I m developing this as a standalone appln.
Plz help..
Thanking in advance.

Thanx fouadk ,
But my problem still persists. Now though I m able to add JPanel to JScrollPane, but when the components in the JPanel increase than the height of the Pane, the components at the dowm are not visible unless I resize the window by manually dragging the corners. Actually I wanted to keep the size of the window constant and make use of the VERTICAL SCROLLBAR.
Plz help.
Thanking in advance.
Following is code:
import javax.swing.*;
public class testt extends JFrame {
private JPanel p = new JPanel();
private JScrollPane sp = new JScrollPane(p
,JScrollPane.VERTICAL_SCROLLBAR_ALWAYS
,JScrollPane.HORIZONTAL_SCROLLBAR_ALWAYS);
private JButton b[] = new JButton[15];
public testt() {
super("TEST");
setDefaultCloseOperation(EXIT_ON_CLOSE);
setSize(500, 400);
setLocation(50, 20);
this.add(sp);
p.setLayout(null);
sp.setAutoscrolls(true);
for(int i = 0, y = 10; i < 15; i++, y += 40)
     b[i] = new JButton("BUTTON "+ (i+1));
     b.setBounds(10,y,100,20);
     p.add(b[i]);
public static void main(String[] args) {
testt t = new testt();
t.setVisible(true);
