How to configure Expires Filter in Tomcat 7

Question

I'm using grails 2.0.0. I want to add expires header for static files in tomcat. As per the tomcat docs i added the foll filter mapping in web.xml

<filter>
 <filter-name>ExpiresFilter</filter-name>
 <filter-class>org.apache.catalina.filters.ExpiresFilter</filter-class>
  <init-param>
   <param-name>ExpiresDefault</param-name>
   <param-value>access plus 1 year</param-value>
 </init-param>
</filter>

<filter-mapping>
 <filter-name>ExpiresFilter</filter-name>
 <url-pattern>/*</url-pattern>
 <dispatcher>REQUEST</dispatcher>
</filter-mapping>

After adding this , my application is not coming up

I'm getting the foll error in stacktrace.log :

The IllegalStateException error is not related to your question — Konstantin Kolinko, Dec 08 '14 at 09:03
@KonstantinKolinko I get this error only when i add expire filter in web.xml file. If i remove this filter, then everything works fine. — Manisha, Dec 08 '14 at 09:32
In param-value, it should be 'access plus 1 years'. 's' was missing in the value. With this change, Expires filter is working — Manisha, Dec 08 '14 at 11:00
Good that you fond the cause. I filed this into Tomcat Bugzilla, https://issues.apache.org/bugzilla/show_bug.cgi?id=57331 — Konstantin Kolinko, Dec 08 '14 at 21:38
Still, that IllegalStateException is not the first failure that happens. There should be an earlier error that is logged into localhost.$date.log file. It looks like javax.servlet.ServletException: Exception processing configuration parameter "ExpiresDefault":"access plus 1 year" — Konstantin Kolinko, Dec 08 '14 at 21:47

You should use the asset-pipeline plugin and its addon plugins for this. They're actively maintained, very well integrated with Grails, and you'll get a lot more than just expires headers - gzipping/minification, bundling, integration with less, sass, and coffeescript, and more that I'm forgetting.
