filter-mapping dispatcher tag error

Question

I am trying to use leverage browser caching for my web css, js files. I was following this http://tomcat.apache.org/tomcat-7.0-doc/config/filter.html#Expires_Filter , which says to add-

<filter>
 <filter-name>ExpiresFilter</filter-name>
 <filter-class>org.apache.catalina.filters.ExpiresFilter</filter-class>
 <init-param>
 <param-name>ExpiresByType image</param-name>
 <param-value>access plus 10 minutes</param-value>
 </init-param>
 <init-param>
 <param-name>ExpiresByType text/css</param-name>
 <param-value>access plus 10 minutes</param-value>
 </init-param>
 <init-param>
<param-name>ExpiresByType application/javascript</param-name>
<param-value>access plus 10 minutes</param-value>
</init-param>
</filter>
...
<filter-mapping>
<filter-name>ExpiresFilter</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
</filter-mapping> 

in web.xml. But inside filter-mapping tag dispatcher tag showing error

The content of element type "filter-mapping" must match "(filter-name,(url-pattern|servlet-name))".

which means I think that content inside filter-mapping should be only filter-name and url-pattern|servlet-name. I also tried urlRewriter also as suggested in answer configuring Tomcat for leveraging browser caching? but stukc in same problem. Please someone explain this.
