XML : JSP XML Filter not working

I am trying to filter first jsp pages then the servlet, using the below code. But, it's not working. Even, the Server(Apache-Tomcat) does not start.

  <?xml version="1.0" encoding="UTF-8"?>  <web-app xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xmlns="http://java.sun.com/xml/ns/javaee" xsi:schemaLocation="http://java.sun.com/xml/ns/javaee http://java.sun.com/xml/ns/javaee/web-app_2_5.xsd" id="WebApp_ID" version="2.5">   <display-name>Practice_Servlet</display-name>   <welcome-file-list>     <welcome-file>index.jsp</welcome-file>   </welcome-file-list>     <servlet>  <description>  </description>  <display-name>Servlet_Main</display-name>  <servlet-name>Servlet_Main</servlet-name>  <servlet-class>com.rohit.controller.Servlet_Main</servlet-class>  </servlet>  <servlet-mapping>  <servlet-name>Servlet_Main</servlet-name>  <url-pattern>/Servlet_Main</url-pattern>  </servlet-mapping>    <filter>    <filter-name>jspF</filter-name>    <filter-class>com.rohit.controller.JspFilter</filter-class>    </filter>    <filter-mapping>    <filter-name>jspF</filter-name>    <url-pattern>/*.jsp</url-pattern>    </filter-mapping>      <filter>    <filter-name>ServletFilter</filter-name>    <filter-class>com.rohit.controller.DispatchFilter</filter-class>    </filter>    <filter-mapping>    <filter-name>ServletFilter</filter-name>    <url-pattern>/Servlet_Main</url-pattern>    </filter-mapping>   </web-app>
