假定你的web application 名称为news，你在浏览器中输入请求路径：


http://localhost:8080/news/main/list.jsp


1.1 System.out.println(request.getContextPath());


打印结果：/news


1.2 System.out.println(request.getServletPath());


打印结果：/main/list.jsp


1.3 System.out.println(request.getRequestURI());


打印结果：/news/main/list.jsp


1.4 System.out.println(request.getRealPath("/"));


打印结果：F:Tomcat 6.0webapps ews
