JtextArea Key Filter

I want to filter the keystrokes on a JTextArea so that certain characters won't be displayed.

I tried to dispatch a backspace after the filtered characters using:

console.dispatchEvent(new KeyEvent( sp, KeyEvent.KEY_PRESSED , System.currentTimeMillis(), 0, KeyEvent.VK_BACK_SPACE, (char) 8));

But I couldn't get it to work.

How can I achieve this?

Thanks,
