Again, message to everyone: read Swing tutorial of javasoft! It can
answer to most of the questions!

So, coming back to the question, the solution is following:
====================
 .....
static int NUMBER_OF_CHARS = 1;

JTextField jtf = new JTextField();
jtf.setDocument(new LimitedCharsDocument())
....

class LimitedCharsDocument extends DefaultStyledDocument{
  public void insertString(int offs, String str, AttributeSet a)
                         throws BadLocationException {
    if ((getLength() + str.length()) <= NUMBER_OF_CHARS)
       super.insertString(offs, str, a);
    else
       Toolkit.getDefaultToolkit().beep();
    }
}
========================
If u want to get extended info about JTextComponent, just email me, and
i'll send u some pages from that tutorial.
