非常完善的OA（办公管理系统）开发环境：Visual Studio .NET 2005 + Server2005运用HTML/JavaScript/CSS技术实现标准、规范的客户端静态和动态效果(failed to translate)

本代码只是简单实现了办公系统的一小部分，使用struts等框架，只适合初学者参考。(This code simply implements a small part of office systems, such as using the struts framework, reference is only suitable for beginners.)

TODO(code review): Curious question.. Why are a lot of these methods not declared as static, since they do not seem to require any local object state? Assumedly this cannot be changed without interfering with the API..

实现一个程序，对用户输入的类权限、成员权限、以及使用该类对象的环境与这个类的关系，判断这个环境中能不能访问这个类的这个成员。 4． 背景知识介绍：对类成员的访问权限由3个方面决定：（1）类的访问权限（public或default），（2）成员变量的访问权限（public, protected, default或private），以及环境与类的相互关系（同类SameClass，同包不同类SamePackageNoteSameClass，不同包但为子类OtherPackageSubClass，不同包非子类OtherPackageNotSubClass）。例如，如果一个类A是public的，它的一个成员变量x是protected的，则这个成员变量的访问权限是default的，试图访问这个类的一个运行环境与A的关系是OtherPackageSubClass，则这个环境中能够访问变量x。(Implement a program, the relationship between the classes of permissions, user input member permissions, as well as the environment of use of such objects of this class, it is judged in this environment can not access this members of this class. 4. Background knowledge: the access rights of the class members decided by three aspects: (1) access rights (public or default), (2) the member variable access rights (public, protected, default or private), as well as environmental and the relationship of the class (of similar SameClass, same package different classes SamePackageNoteSameClass, different packages, but for subclass OtherPackageSubClass, different package non-subclass OtherPackageNotSubClass). For example, if a class A is public, it s a member variable x is protected, the access rights of the member variables is default, tries to access a runtime environment for this class A relationship is OtherPackageSubClass this environment be able to access the variable x.)

说明：  自学Java写的象棋游戏源码（简单），希望高人不要笑话，这是我自学写的，基本上是用Java调用图片显示的原理制成，适合和我一样菜的Java新手，希望大家与我一起交流。 (Learning chess game written in Java source code (simple), I hope skilled are not a joke, this is my self-written with Java call is basically the principle of image display is made of the same dish for my Java novice, and I hope with the exchange.)

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)
