RMI is Remote Method Invocation. With RMI, you can access the methods of remote objects. In more detail, on one computer, the server, you run:

• the RMI-Registry program;

and:

• a Java application that registers one or more Java objects with the RMI-Registry.

And, on the other computer, the client computer, you run:

• a Java application that accesses the methods of the objects of the application running on the server.
