Answer:

Source: CoolInterview.com

RMI, Remote Method Invocation is an alternate to RPC, used to invoke the methods (often called as Services) provided by an object of One JVM in another JVM.

This is the Remoting Technology that is supported by Java.
This technology can be used in case of Java to Java only.

1. Whenever you use RMI, we need to develop the Remote Interface, A class that implements that Remote Interface.

2. We need to register the Object in a Registry.

3. Start the Server.

4. Lookup for the object in the registry and get the object.

The following is the Architecture of the RMI:

1. RMI consists of the following components:
a. Server: This JVM contains an object that provides the remote services. It registers its object into the Registry.
b. Stub: This is generated in the server. This is used to understand or translate the request and response formats of the server and client in the server.
c. Client: This is the program that accesses the RMI Registry for the services of the server.
d. Skeleton: This is a class that remains in Client and help teh client to understand the request and response formats of server in client.
e. RMI Registry: This is a Naming Registry that is used to bind the objects and return their references to the client.

Note: When ever a client request for the object's reference, logical reference of the stub is returned but not the actual reference of the object. Source: CoolInterview.com
