远程接口调用
Remote Method Invocation

远程接口调用(RMI)是一个分布式系统技术,它允许JVM去调用对象的方法,将在网络中另一个JVM上运行。这是大型系统的重要发展,因为它可以使分配资源和超过处理负载一台机器成为可能。

设计一个RMI彩票应用程序。每次运行客户端程序——“java彩票客户端n”,服务器程序“彩票服务器”将生成n组彩票号码。这里n是一个正整数,表示你将花在彩票上的英镑。

客观的任务是实现一个RMI彩票应用程序，将采用相似的国家彩票的工作方式来随机生成数字。我已经实现了RMI这样一种方式,每次彩票客户端运行它,它将产生六个数字，客户愿意花每英镑在我的RMI彩票应用程序。彩票号码和国家彩票一样，在1-49之间。

RMI应用程序由两个独立的程序,服务器和客户端程序。
典型的服务器程序创建远程对象
对这些对象的引用
服务器等待客户端调用这些对象的方法

典型的客户机程序获得远程服务器上的远程对象的引用,并调用它们的方法。RMI负责服务器和客户端之间的通信。

RMI是一个系统,用于客户端和服务器通信通常分为两类。服务器提供了一个RMI服务和客户机调用这个对象的方法。

RMI服务器注册与查找服务,为了让客户找到他们,或者他们将提供以其他方式服务的引用。

Remote Method Invocation (RMI) is a distributed systems technology that allows JVM to invoke object methods that will run on another JVM in a network. This is important for the development of large systems, as it makes it possible to distribute resources and processing load across more than one machine.

Designing a RMI Lottery application. Each time you run the client program -- 'java LotteryClient n', the server program 'LotteryServer' will generate n sets of Lottery numbers. Here n is a positive integer, representing the money you will spend on Lottery in sterling pounds.

An objective of this task is to implement a RMI Lottery application that will generate random numbers similar the way the national Lottery works. I have implement the RMI in such a way that every time the LotteryClient is run it, it will generate six numbers for every sterling pound the client is willing to spend on my RMI Lottery application. The lottery numbers will be between 1 and 49 same way as the national lottery

RMI applications consist of two separate programs, a Server and a Client program.
A typical Server program creates remote objects
Makes references to these objects accessible
Server waits for clients to invoke methods on these objects.

A typical client program obtains a remote reference remote object on the server and invokes the methods on them. The RMI is responsible for the communication between the server and the client

RMI的文献综述——LITERATURE REVIEW OF RMI

RMI是如何工作的——HOW DOES RMI WORK

RMI is a system that is used for communication typically divided into two categories a Clients and Servers. A server provides an RMI service, and a client invokes this object methods.

The RMI servers hast to register with a lookup service, in order to allow clients to find them, or they will make available a reference to the service in some other fashion. An application called rmiregistry, runs as a separate process and allows applications to register RMI services or obtain references to a named service.

According to [4], when the server has registered, it will then just sit idle and wait for incoming RMI requests from clients.

创建RMI系统必不可少的步骤——STEPS IN CREATING AN RMI SYSTEM

According to [2], the essential steps in creating an RMI system are as follows: define interface, implementation of remote object, create a stub using MIR write server and write client.
