Singleton class instantiated several times

Question

Hi all,
I am trying to implement an inter-applet communication using a singleton class for registering the applets. The applets are in different frames on my browser; they are placed in the same directory and they use the same java console, so I am pretty sure they are running on the same JVM...
However, when I register my applets, every applet creates its "own" registry class. I have put a message in the constructor of the register class to check what's happening:
public class AppletRegistry extends Applet 
    //static hashtable maintaining the applet map
    private static Hashtable appletMap;
    private static int ct=0;
    protected static AppletRegistry registry;
    protected AppletRegistry()
        appletMap = new Hashtable();
//  Returns the long instance of the registry. If there isn't a registry
//  yet, it creates one.
      public synchronized static AppletRegistry instance()
           if (registry == null) {
                     System.out.println("new register");
                registry = new AppletRegistry();
           return registry;
    //registers the given applet
    public void register(String name, Applet applet)
        appletMap.put(name, applet);
        ct++;
        System.out.println("Register: "+name+" "+Integer.toString(ct));
}The output "new register" appears for every applet I register... What am I doing wrong?

I must admit that I never heard of classloader until
now :-( (learning java for two or three months). Do
you know a good tutorial about using classloaders? I
have no idea where to start checking which
classloaders are used.
Thanks!
TheaHi,
I don't think there are much you can do about it. Two different applets can't share an instance.
