JFormattedTextField : input time duration value

Question

I want to use a JFormattedTextField to allow the user to input time duration values into a form. Sample valid values are:

2h 30m
72h 15m
6h
0h

However I am having limited success with this. Can some one please suggest how this can be accomplished? I am OK if this result can be achieved using a JTextField as well.

Thanks!

If it is worth anything, here's my current attempt:

 mFormattedText.setFormatterFactory(
    new DefaultFormatterFactory(
        new DateFormatter(
            new SimpleDateFormat("H mm"))));

This sorta works except that:

• I cannot get h and m to appear as plain text (I tried escaping) *
• The number of hours has a max

The code:

public static void main(String[] args) {
    JFrame jFrame = new JFrame();
    jFrame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    jFrame.setLayout(new BorderLayout());
    jFrame.setPreferredSize(new Dimension(500, 500));

    final JFormattedTextField comp = new JFormattedTextField();
    comp.setFormatterFactory(new DefaultFormatterFactory(new DateFormatter(new SimpleDateFormat(
            "H'h' mm'm'"))));
    comp.setValue(Calendar.getInstance().getTime());

    comp.addPropertyChangeListener("value", new PropertyChangeListener() {

        @Override public void propertyChange(PropertyChangeEvent evt) {
            System.out.println(comp.getValue());

        }
    });

    jFrame.getContentPane().add(comp, BorderLayout.CENTER);

    jFrame.pack();
    jFrame.setVisible(true);
}
