Unicast Remote Object

[Manas Shukla]

hi all
i am new to java
therefore my question may not be apt for this forum
But why does implementation class has to extend UnicastRemoteObject ???

[Andrey Kozhanov]

Actually, implementation class does not necessary has to extend UnicastRemoteObject. RMI goal is to make objects remotely accessible. There are two ways of doing this:

1. Extend UnicastRemoteObject

2. Call static method UnicastRemoteObject.exportObject with your implementation class as a parameter.

As far as i know, using UnicastRemoteObject either way is required by RMI server.
