(4) Tomcat 工程（也就是以Variable形式Import 了servlet-api.jar, jsper-runtime.jar, jsp-api.jar ）
(5)其它jar: Import spring.jar, taglib.jar, log4j.jar, cglib.jar, commonds-xxxx.jar, 以Variable 形式Import进jstl-1.1.jar，否则报错：jstl相关类找不到
(6)有点怪！ Spring.jar 必须：放在工程lib 或Tomcat/commom/lib 下, 或者以Variable 的形式import， 否则会报错：找不到 DispatcherServlet
