It's magic. I reckon there was another problem or misspelling. Following your
first advice again I put the following lines in my web.xml and all works
well:
<filter-mapping>
<filter-name>struts</filter-name>
<url-pattern>/*</url-pattern>
<dispatcher>REQUEST</dispatcher>
<dispatcher>FORWARD</dispatcher>
</filter-mapping>
By default only requests are allowed but no forwards! That's it.
