public class FirstApplet extends Applet {
     private boolean authentified = false;
     private SecondApplet applet = null;
     public void init() {
          System.out.println("FirstApplet: init()");
          authentified=authentificate();
     public void start() {
          System.out.println("FirstApplet: start() "+authentified);
          if (authentified==true) {
               applet=new SecondApplet();
               applet.init();
               applet.start();
     public void stop() {
          System.out.println("FirstApplet: stop()");
          if (applet!=null) applet.stop();
     public void destroy() {
          System.out.println("FirstApplet: destroy()");
          if (applet!=null) applet.destroy();
     private boolean authentificate() {
          System.out.println("FirstApplet: authentificate()");
          // ask the user for username and password
          // check the password, if it's ok, return true
          // if it's not okay, return false
          // how to do a login window, see

          return true;
