 System.setSecurityManager(new RMISecurityManager());
 System.out.println("Initialising server please woai");

Reason: You did not specify the policy file on the command line should be something like:
java -cp . -Djava.security.policy=policyfile myprogram

i am haveing the same problem. the diff is that the problem is coming when i am running the client program from diff machine & try to access the client m/c
Error is
java.security.AccessControl.Exception(IP:socket).....
Also i am trying to connect thru the aPPLET.
You have clarified the doubt But what should be the content of the policyfile & where should it be stored???

Check the following link for contents of policy file http://java.sun.com/products/jdk/1.2/docs/guide/security/permissions.html

Hi
Just comment the SecurityManager line and recompile. It will work fine.
