1.1 作业描述 设计一个生成和显示时间的分布式应用程序，实现以下功能： 1、 一个服务器生成时间，并在多个不同节点的客户端上显示。 2、 客户端有多种时间显示方式，如模拟时钟、数字时钟。 1.2 作业要求 下面是设计时需要满足的四个要求： 1、 打破客户端和服务器开发过程中的紧耦合。 2、 打破客户端和服务器运行时的紧耦合，即不需要固定的机器，不限制客户端的数目等。 3、 允许客户端显示不同的事件。 4、 使用RPC机制或RMI机制。 (1.1 Design a job description to generate and display time distributed applications, the following functions: 1, a time server generates and displays on the client several different nodes. 2, the client has a variety of time display, such as an analog clock, a digital clock. 1.2 Operating Requirements The following is required to meet four design requirements: 1, breaking client and server development process tightly coupled. 2, breaking the tight coupling client and server runtime that does not require a fixed machine, does not limit the number of clients and so on. 3, allows clients to display different events. 4, using the RPC mechanism or RMI mechanism.)
