关于客户端、Servlet与Web容器的交互说法错误的是（）。A、一个基于servlet应用的客户通常不直接和servlet通信，而是由Web应用服务器通过Java Servlet API调用servlet来实现请求servlet的服务B、Servlet是由Web应用服务器中的Web Container管理的。Web容器的角色是管理装载和初始化servlet，处理服务请求，卸载或撤销servletC、一般来说，某一时刻在web容器中只有一个特定的servlet对象的实例，这是servlet持久性的基本原理。每次客户端调用servlet时，web容器都负责实现servlet的初始化D、每一个客户对servlet的请求都会创建servlet的一个对象实例。Web容器负责创建每个处理请求的新实例。另外它还负责最后的卸载或重新安装servlet。卸载和重新安装通常发生在web应用服务器崩溃或者支持servlet的文件改变时
