I want to know that in RMI application we need to create a remote interface that contane the method which has been remotely invoked and a class that will implement that remote interface.

Here tell me one thing that why we make a remote interface what is need of that interface ? why we not make only implementation class that method will call remotely.
I mean in RMI application what is need of Interface why not just a class only.

The reason for using an interface is the same as it is everywhere - to provide a layer of abstraction. It allows the implementating class to change without the client code needing to be adapted.
