I would suggest the Window.setLocationRelativeTo(Component) method, which will center the window relative to a specified component. Instead of passing in a JDesktopPane, you might want to obtain the parent frame for a component, since otherwise, your JInternalFrame will be centered according to whichever component you pass in.

Here is a code sample:

    Frame frame = JOptionPane.getFrameForComponent(button);
    dialogToCenter.setLocationRelativeTo(frame);
    dialogToCenter.setVisible(true);
