I your JFrame you must declare a JDesktopPane and before create JInternalFrame inside it:
public class MDIFrame extends JFrame{     
JDesktopPane desktop = new JDesktopPane();               
public MDIFrame(){     
     JInternalFrame child = new JInternalFrame();     
     this.getContentPane().add(desktop);
desktop.add(child);
child.setSize(400,400);
child.setVisible(true);
public static void main(String arg[]){
new MDIFrame().setVisible(true);
}
