在web.xml中配置加载applicationContext.xml中总说找不到类?

11:53:49,541 INFO [/jsfDemo]:638 - Marking servlet SpringContextServlet as unavailable

这是我每次重起服务器不时候的异常信息
web.xml

"-//Sun Microsystems, Inc.//DTD Web Application 2.3//EN"
"http://java.sun.com/dtd/web-app_2_3.dtd">


javax.faces.CONFIG_FILES
/WEB-INF/faces-config.xml

contextConfigLocation
/WEB-INF/applicationContext.xml



com.sun.faces.config.ConfigureListener


SpringContextServlet
org.springframework.web.context.ContextLoaderServlet
1


Faces Servlet
javax.faces.webapp.FacesServlet
1


Faces Servlet
*.faces


index.html


我也这样写是找不到这个类
org.springframework.web.context.ContextLoaderListener

applicationContext.xml.
