Hello, all !!!

Could somebody explain, why my JDialog with SpringLayout doesn't work:

...
public class OptionsDialog extends JDialog
{
    JLabel label;

    public OptionsDialog()
    {
      Container pane = getContentPane();

      SpringLayout layout = new SpringLayout();
      pane.setLayout(layout);

      label = new JLabel("Select plugins directory: ");

      pane.add(label);

      layout.putConstraint(SpringLayout.WEST, label, 20, SpringLayout.WEST,
pane);
      layout.putConstraint(SpringLayout.NORTH, label, 20,
SpringLayout.NORTH, pane);

      pack();
      setVisible(true);
    }

    public static void main(String args[])
    {
        OptionsDialog dlg = new OptionsDialog();
    }
}

Dialog has only title and no even space for label.

Thanx.
