则执行下面向行代码后打印出如下结果：

 

1、 System.out.println(request.getContextPath());

 

打印结果：/news

2、System.out.println(request.getServletPath());

 

打印结果：/main/list.JSP

3、 System.out.println(request.getRequestURI());

 

打印结果：/news/main/list.JSp

 4、 System.out.println(request.getRealPath("/"));

 

打印结果：F:\tomcat 6.0\webapps\news\test
