   </context-param>
   <context-param>
        <param-name>webAppRootKey</param-name>  
        <param-value>myappfuse.root</param-value>  
    </context-param> 
   <context-param>
      <param-name>log4jRefreshInterval</param-name>
      <param-value>6000</param-value>
   </context-param>
    <listener>
      <listener-class>
        org.springframework.web.util.Log4jConfigListener

   </listener>
