说明：  JDWP 是 Java Debug Wire Protocol 的缩写，它定义了调试器（debugger）和被调试的 Java 虚拟机（target vm）之间的通信协议。 JDWP 协议介绍 这里首先要说明一下 debugger 和 target vm。Target vm 中运行着我们希望要调试的程序，它与一般运行的 Java 虚拟机没有什么区别，只是在启动时加载了 Agent JDWP 从而具备了调试功能。而 debugger 就是我们熟知的调试器，它向运行中的 target vm 发送命令来获取 target vm 运行时的状态和控制 Java 程序的执行。Debugger 和 target vm 分别在各自的进程中运行，他们之间的通信协议就是 JDWP。(JDWP is Java Debug Wire Protocol)

dspace1.7.2源码，DSpace（数字空间）系统是由美国麻省理工学院图书馆（MIT Libraries）和美国惠普公司实验室（Hewlett-Packard Labs）合作经过两年多的努力并于2002年10月开始投入使用的，以内容管理发布为设计目标，遵循BSD协议的开放源代码数字存储系统。该系统可以收 集、存储、索引、保存和重新发布任何数字格式、层次结构的永久标识符研究数据。 (dspace1.7.2 source, DSpace (digital space) systems by the U.S. Massachusetts Institute of Technology Library (MIT Libraries) and the U.S. Hewlett-Packard Laboratories (Hewlett-Packard Labs) co-operation, and after two years of hard work began in October 2002 put to use to publish content management for the design of the target, follow the open source BSD license digital storage systems. The system can collect, store, index, preserve and re-publish any digital format, a permanent identifier for the hierarchy of research data.)

说明：  本系统是基于java开发的聊天室。服务端和客户端可以发送和接收消息，由于未写出服务端窗口，聊天记录只会在输出的窗口显示。如果服务器还未启动，客户端不能利用聊天室发消息。若在运行过程中服务器断开，系统会有提示。(This system is a chat room based on java. Both the server and the client can send and receive messages. Since the server window is not written out, the chat record will only be displayed in the output window. If the server has not been started, the client can not use the chat room to send messages. If the server is disconnected during operation, the system will be prompted.)
