Java APIs

Hi,

I am following the JGuru RMI tutorials and while working on the Parametes tutorial;
http://java.sun.com/developer/onlineTraining/rmi/exercises/RMIParameters/index.html

I encountered the following exception when running the RMIServer part;

Parameters>java RMIServer
Registry created on host computer localhost on port 10002
Remote HelloService implementation object created
Exception in thread "main" java.security.AccessControlException: access denied (

        at RMIServer.<init>(RMIServer.java:75)
        at RMIServer.main(RMIServer.java:37)

To fix the problem I had to remove the following line of code from RMIServer.java;

System.setSecurityManager( new RMISecurityManager() );

Is there additional configuration I need to perform in order to use a security manager? I am running on Windows XP Pro.

Regards,
