You need two <filter-mapping> elements, and I'd put your filter first. Change:

<filter-mapping>
 <filter-name>struts2</filter-name>
 <url-pattern>/*</url-pattern>

 <filter-name>Set Character Encoding</filter-name>
 <url-pattern>/*</url-pattern>
</filter-mapping>

To:

<filter-mapping>
 <filter-name>Set Character Encoding</filter-name>
 <url-pattern>/*</url-pattern>
</filter-mapping>
<filter-mapping>
 <filter-name>struts2</filter-name>
 <url-pattern>/*</url-pattern>
</filter-mapping>
