Keymap usage in Swing

Question

I've used <b>setKeyCode()</b>method of Keymap interface to trap key events in a <b>JTextField(in the keyPressed() method).</b>
It's not working with Swing, but is working with AWT.(TextField)
Anybody please get me the the details and its usage in Swing.

public class sundar_ind extends JFrame implements KeyListener {
