Full solved answer →RMI architecture and components
Explain the architecture of RMI. [5]
RMI is a Java mechanism that allows a program running on one JVM to invoke methods on objects residing in another JVM. The architecture consists of the following layers: - Contains the client and server applications - Client invokes remote methods as if the...

Distributed programs in Java can be written using several approaches: 1. Socket Programming - Using TCP/IP sockets for low-level network communication between Java applications 2. RMI (Remote Method Invocation) - Allows Java objects to invoke methods on rem...
Full solved answer →Steps of writing RMI programs
Discuss the steps of writing RMI programs. [5]
RMI (Remote Method Invocation) allows Java programs to invoke methods on objects located in other JVMs across a network. Writing RMI programs involves a structured sequence of steps. - Create an interface that extends java.rmi.Remote - Declare all methods t...
