Help:why cann't open socket through registry?

Question

This is an example from book,but i cann't register the object in the registry.
and the file %JAVA_HOME%\lib\ext\java.policy has the line:
permission java.net.SocketPermission "localhost:1024-", "listen";
it means u can use port 1099.
but when i run java RegisterIt,an error occured.
message as follow:
G:\javasource>java RegisterIt

          HelloServer obj=new HelloServer();
          System.out.println("Object instantiated:"+obj);     
          Naming.rebind("/HelloServer",obj);
          System.out.println("HelloServer bound in registry");
     }catch(Exception e){
          System.out.println(e);
}

check if rmiregistry is running on the default port(1099) on your localhost.
If not, run it like this on unix.
$ rmiregistry 1099&
I assume your HelloServer's implementation is fine.
