Hi, 

I have problem to get page 71 to work. I type the following:

1. javac *.java
2. rmic HelloServer
3. rmiregistry -J-Djava.security.policy=registerit.policy
4. rmid -J-Djava.security.policy=registerit.policy
5. java -Djava.security.policy=registerit.policy 
-Djava.rmi.server.codebase=file://c:/projavaserver/chapter02/activatable/ RegisterIt

but I got invalid port range : 21

if there is no error, then I will type 

6. java HelloClient localhost

What is the step to make it work?

Thanks.
