Answer / vatsal doshi
There are many purposes for using a Unicast Remote Object
1. All the basic functionalities of RMI are actualy
implemented in this class. When we extend this class, in our
Remote class, all the RMI code gets inherited and becomes
available in our class
2. UnicastRemoteObject also implements Serializable
interface. So your subclass also automatically implements
Serializable. And thus marshalling is then supported for
your type
3. UnicastRemoteObject also prevents the methods of Object
class from being directly inheritted into the Remote class.
Thereby, preventing the 11 methods of Object class from
being invoked Remotely. methods like hashcode() need
different implementations for Remote invocations.

Answer / yogesh
If you extends this class, your object will be automatically exported for RMI access.
If your class is already extending another class, or you just don't like extending from UnicastRemoteObject, you can also do the following:
UnicastRemoteObject.exportObject ( this );
