web.xml应包含以下内容：

<servlet>

         <servlet-name>jsp</servlet-name>

         <servlet-class>org.apache.jasper.servlet.JspServlet</servlet-class>

         <init-param>

             <param-name>fork</param-name>

             <param-value>false</param-value>

         </init-param>

         <init-param>

             <param-name>xpoweredBy</param-name>

             <param-value>false</param-value> 

        </init-param>

    ***<init-param> 
            <param-name>mappedfile</param-name>
             <param-value>false</param-value>
        </init-param>***

        <load-on-startup>3</load-on-startup>

   </servlet>

方法_jspService（HttpServletRequest，HttpServletResponse）的代码超出了65535个字节的限制
