Apart from having all jars, you need to make a manual filter entry in your web.xml

<filter>
        <filter-name>struts2</filter-name>
        <filter-class>org.apache.struts2.dispatcher.FilterDispatcher</filter-class>        
    </filter>
    <filter-mapping>
        <filter-name>struts2</filter-name>
        <url-pattern>/*</url-pattern>
    </filter-mapping>

FilterDispatcher is obsolete use StrutsPrepareAndExectueFilter.
