KeyStroke Problem (except ENTER) in Textfield

Question

I like to activate and track within KeyLisener all keys like...Esc key, Shift-Tab key or any other key while in a Text Field .
I have tried a lot... but failed.
I used this code...
txtBillNo.addKeyListener(new java.awt.event.KeyAdapter()
public void keyPressed(KeyEvent e)
if ( ( (e.getModifiers() == KeyEvent.SHIFT_MASK) &&
(e.getKeyCode() == KeyEvent.VK_TAB))
||
( (e.getKeyCode() == KeyEvent.VK_ENTER)
||
(e.getKeyCode() == KeyEvent.VK_TAB)))
System.out.println("xxxxxxxxxxxxx ");

Hi. Try this code:
The problem is the focusmanager is handling the tab event so it never gets to the listener. If you disable the manager, then the key listener can get a crack at the event.
     public static void main(String[] args) {
          JTextField txtBillNo = new JTextField     ("adfasdfasf");
          txtBillNo.setFocusTraversalKeysEnabled(false);
          txtBillNo.addKeyListener(new java.awt.event.KeyAdapter() {
               public void keyPressed(KeyEvent e) {
                    if ((((e.getModifiersEx() & KeyEvent.SHIFT_DOWN_MASK)
                         == KeyEvent.SHIFT_DOWN_MASK)
                         && (e.getKeyCode() == KeyEvent.VK_TAB))
                         || ((e.getKeyCode() == KeyEvent.VK_ENTER)
                              || (e.getKeyCode() == KeyEvent.VK_TAB))) {
                         System.out.println("xxxxxxxxxxxxx ");
          JFrame frame = new JFrame();
          frame.getContentPane().add(txtBillNo);
          frame.pack();
          frame.show();
     }
