Java Remote Method Invocation (RMI)

(https://en.wikipedia.org/wiki/Java_remote_method_invocation)

The Java Remote Method Invocation (Java RMI) is a Java API that performs remote method invocation, the object-oriented equivalent of remote procedure calls (RPC), with support for direct transfer of serialized Java classes and distributed garbage collection.

1. The original implementation depends on Java Virtual Machine (JVM) class representation mechanisms and it thus only supports making calls from one JVM to another. The protocol underlying this Java-only implementation is known as Java Remote Method Protocol (JRMP).
2. In order to support code running in a non-JVM context, a CORBA version was later developed.

Usage of the term RMI may denote solely the programming interface or may signify both the API and JRMP, IIOP, or another implementation, whereas the term RMI-IIOP (read: RMI over IIOP) specifically denotes the RMI interface delegating most of the functionality to the supporting CORBA implementation.

The basic idea of Java RMI, the distributed garbage-collection (DGC) protocol, and much of the architecture underlying the original Sun implementation, come from the ‘network objects’ feature of Modula-3.

Fundamentals of RMI – Short Course
(http://dsnet.tu-plovdiv.bg/website/container/rmi/RMI.html)

Remote Method Invocation (RMI) technology, first introduced in JDK^TM 1.1, elevates network programming to a higher plane. Although RMI is relatively easy to use, it is a remarkably powerful technology and exposes the average Java developer to an entirely new paradigm–the world of distributed object computing.

This course provides you with an in-depth introduction to this versatile technology. RMI has evolved considerably since JDK 1.1, and has been significantly upgraded under the Java 2 SDK. Where applicable, the differences between the two releases will be indicated.

Introduction to Java Remote Method Invocation : RMI – EJB Tutorial
(http://www.ejbtutorial.com/java-rmi/introduction-to-java-remote-method-invocation-rmi)

Java RMI is a specification for how Java Object  can be accessed  Remotely. Java RMI allows programmers to execute remote function class using the same semantics as local functions calls. The implementation of RMI is within the Java Remote Method Protocol ( JRMP ) library. The main Drawback of RMI is that it is a Java to Java Communication only.

A Remote Object is an object that resides on another computer and can be invoked remotely. Remote methods must include in their signature the throws RemoteException.

The Simple scenario for RMI is as follows:

• The server must first bind its name to the registry
• The client lookup the server name in the registry to establish remote references
• The Stub serializing the parameters to skeleton, the skeleton* invoking the remote method and serializing the result back to the stub.

A Step by Step Implementation Tutorial for Java RMI
(http://www.ejbtutorial.com/java-rmi/a-step-by-step-implementation-tutorial-for-java-rmi)

In this RMI Programming tutorial, we will learn how to create :

• Simple Remote Object.
• Server to instantiate (create ) and bind a remote object.
• Client to invoke remotely an object

As RMI is a Java to Java only communication protocol, you need to install the Java Development Kit ( JDK ) as well as a programming editor ( IDE ) such as Eclipse.

Distributed Java: RMI Tutorial by Ian F. Darwin
(http://www.darwinsys.com/java/rmi/)

Remote method invocation allows applications to call object methods located remotely, sharing resources and processing load across systems. Unlike other systems for remote execution which require that only simple data types or defined structures be passed to and from methods, RMI allows any Java object type to be used – even if the client or server has never encountered it before. RMI allows both client and server to dynamically load new object types as required. In this article, you’ll learn more about RMI.

Getting Started Using Java RMI
(http://download.java.net/jdk9/docs/technotes/guides/rmi/hello/hello-world.html)

This tutorial shows you the steps to follow to create a distributed version of the classic Hello World program using Java Remote Method Invocation (Java RMI). While you work through this example, you will probably come up with a number of related questions. You may find answers in the Java RMI FAQ.

The distributed Hello World example uses a simple client to make a remote method invocation to a server which may be running on a remote host. The client receives the “Hello, world!” message from the server.

A Generic Compute Engine
(https://www.cs.ucsb.edu/~cappello/lectures/rmi/computeEngine.html)

This page is based on the Java rmi tutorial on java.sun.com.
The compute engine server:

• accepts tasks from clients
• executes the tasks
• returns any results, if any.

It is comprised of an interface and a class.  The interface defines the client’s view of the remote object, the compute server; the class provides the server’s implementation.

Hello World!
(https://www.cs.ucsb.edu/~cappello/lectures/rmi/helloworld.html)

This is an abbreviated version of Sun’s tutorial titled Getting Started Using RMI.

It is a distributed version of  Hello World using Java RMI.

In the distributed Hello World example, a client makes a remote method call to the server, to retrieve the message “Hello world!”. When the client runs, “Hello world!” is output to the client’s System.out stream.

Hello World! as a Java Applet
(https://www.cs.ucsb.edu/~cappello/lectures/rmi/applet.html)

• We are interested now in focusing on those changes that have to be made to make HelloClient.java an applet.
• In what follows, we assume that the applet runs in the appletviewer.
• Modification are indicated in red.
• In this example, I have created a package called examples.helloApplet.
• To properly access the class files that we create and put into it, we set the CLASSPATH environment variable to the directory in which examples/helloApplet is rooted.
• For example, if our packages our in $home/packages, then we set CLASSPATH to $home/packages.

A Simple Chat Application
(https://www.cs.ucsb.edu/~cappello/lectures/rmi/chatNew.html)

This is a simple chat application.  The basic idea is to have several client applets who chat with each other.  That is, what they type in their TextFields appears on every client’s TextArea—a chat session.  To do this, each client must first register with a server (an act that is posted to all current clients).  When a client contributes a comment, it is sent to the server, who forwards the message to each of the clients.

This basic logic could, for example, be used to implement a collaborative “white board” application.
