电子白板。电子白板有两种实现模型，一种是无白板服务器，因此仅支持两个用户直接连结；另一种是有白板服务器，原则上不限制同时上线人数和交谈室个数，具体实现上可视服务器性能和需要而定。本文要介绍属于后者。----当用户需用白板与他人交流时，需要先用浏览器连到Applet所在主页，Applet运行后会连接到该白板服务器，和服务器建立TCP连接。每个用户可以在自己的白板上（嵌在Applet画面中）绘制图形和输入文字，Applet会将这些信息通过已建立的网络连接发往白板服务器，并不断侦听、接收来自白板服务器的图形和文字信息，将其再现在用户的白板中。白板服务器的作用是不断侦听、接收来自各Applet的信息，并将其转发给其他用户。----由于浏览器对JAVAApplet的限制，使得Applet只能访问发送该Applet的宿主主机，因此只能在该Applet所在主机上运行白板服务器，使得Applet能建立和远程白板服务器的联系。功能设计----一个实用的电子白板系统应该具备以下基本功能：用户在浏览到白板主页时，需登录后才能进行交流。这将提供交流时用的名字，必要时还可做权限检查。用户能够根据交谈室的交谈主题选择参加和退出现有的交谈室，并且能建立新的交谈室。-Whiteboard. Whiteboard realize there are two models, a server is no whiteboard, it only supports two users direct links; Another server is a whiteboard, in principle, while restrictions on the number line chat rooms and the number, concrete realization of server performance and visualization needs. This paper introduces belong to the latter.- When the user needed whiteboard sharing with others, the need to deal with browser connected to the host Applet Home, Applet operation will connect the whiteboard to the server and server TCP connection. Each user can in their own whiteboard (containing the applet screen) rendering graphics and text input, Applet will these messages through the network has been established to connect the whiteboard server, and continuously monitors and coming from th
