Throwing Security Exception while executing RMI Server

Hi
In JDK 1.2 (RMI), i written server class extending UnicastRemoteObject
and written methods in the class. Similarly i written Client side which invokes remote objects in the server.
RMI registry is also running. Is there is any difference between in JDK 1.1.5 and JDK 1.2 with respect to java.policy file.

But I am getting the error while rebinding the object to the register as follows
