Making the Tab key not work in the JTextArea

Question

In my view I have a JTextArea along with a bunch of JTextFields and JComboBoxes. The user is usually going to tab out of a field in order to go to the next field. What's happening is when the user tries to tab out of the JTextArea, the cursor just moves by a tab length within the JTextArea instead of going to the next field. And if the JextArea has some text in it and if the user tabs into the JTextArea, the whole text gets selected and on hitting the next tab, it gets wiped out.
I am trying to make the JTextArea not respond to the tab by writing the following code. Keymap keyMap = JTextComponent.getKeymap(JTextComponent.DEFAULT_KEYMAP);
KeyStroke tabKey = KeyStroke.getKeyStroke(KeyEvent.VK_TAB, 0, false);
keyMap.removeKeyStrokeBinding(tabKey);
jTextArea1.setKeymap(keyMap);But it's still not working. Can anybody tell what's wrong with that code. Or is there any other way to do it? Any help/hints appreciated.
Thanks.

If you're using jdk1.4, those other solutions won't
work because the focus subsystem has changed radically
(see
http://java.sun.com/j2se/1.4/docs/api/java/awt/doc-file
/FocusSpec.html). The upshot is that you have to
specifically register the keystrokes that you want to
use for focus traversal. In your case, you have to
re-register the Tab and Shift-Tab keys, and
they don't seem to have provided a simple way to do
that. Here's what I come up with:Set forwardTraversalKeys = new TreeSet();
forwardTraversalKeys.add(KeyStroke.getKeyStroke(
KeyEvent.VK_TAB));
forwardTraversalKeys.add(KeyStroke.getKeyStroke(
KeyEvent.VK_TAB, InputEvent.CTRL_MASK));
textArea.setFocusTraversalKeys(
KeyboardFocusManager.FORWARD_TRAVERSAL_KEYS,
forwardTraversalKeys);
Set backwardTraversalKeys = new TreeSet();
backwardTraversalKeys.add(KeyStroke.getKeyStroke(
KeyEvent.VK_TAB, InputEvent.SHIFT_MASK));
backwardTraversalKeys.add(KeyStroke.getKeyStroke(
KeyEvent.VK_TAB, InputEvent.SHIFT_MASK |
K | InputEvent.CTRL_MASK));
textArea.setFocusTraversalKeys(
KeyboardFocusManager.BACKWARD_TRAVERSAL_KEYS,
backwardTraversalKeys);Or, you can just press CTRL+TAB instead of TAB when
you get to the JTextArea :).=====================================
i used the above thing but i am getting exceptions classcast exception n method not found (forwardTraversalKeys.add(KeyStroke.getKeyStroke(KeyEvent.VK_TAB));)keystroke.get keyStroke(int)???? where i am going wrong as it will be quite helpful for me am using jdk1.4.1_02
