You could use following constructors to make a JDialog parent-less

JDialog d = new JDialog((Dialog)null);

JDialog d = new JDialog((Window)null);

JDialog d = new JDialog((Frame)null);

Quick code sample :

public class TestFrame extends JFrame{
    public TestFrame(){
        setSize(100,200);
    }

    public static void main(String[] args) {
            //Using null constructor ( Since JDK 6)
        final JDialog loginDialog = new JDialog((Dialog)null);
            //just a button for demo
        JButton okButton = new JButton("Login");
        okButton.addActionListener(new ActionListener() {
            @Override
            public void actionPerformed(ActionEvent ae) {
                TestFrame test = new TestFrame();
                test.setVisible(true);
                loginDialog.dispose();
            }
        });
        loginDialog.getContentPane().add(okButton);
        loginDialog.pack();
        loginDialog.setVisible(true);
    }
}
