Solved: just have a look on
http://cwiki.apache.org/S2WIKI/troubleshooting-guide-migrating-from-struts-20x-to-21x.html
I wish I new such a file existed, it doesn't seem to be often refered to on
google. I stumble upon it while looking for somethig else.
It states:
Filter Mapping, default Action extensions, and Servlets
[...]
To fix this problem you can explicitly set the default action extension back
to just "action" or you can change your filter mapping for the struts
filter.
To set the action extension list back to just "action" add this to your
struts.xml file:
<constant name="struts.action.extension" value="action" />
If all your actions use the ".action" suffix then you may want to change the
Struts filter-mapping so that only actions are handled by the struts filter.
Also the FilterDispatcher has been deprecated and replaced by
StrutsPrepareAndExecuteFilter.
The web.xml before (matching all requests):
<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>
Change to use the new StrutsPrepareAndExecuteFilter and match just struts
requests.
The web.xml after:
<filter>
<filter-name>struts2</filter-name>
<filter-class>org.apache.struts2.dispatcher.ng.filter.StrutsPrepareAndExecuteFilter</filter-class>
</filter>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>*.action</url-pattern>
</filter-mapping>
<filter-mapping>
<filter-name>struts2</filter-name>
<url-pattern>/struts/*</url-pattern>
</filter-mapping>
