This error happens because your struts-config.xml document now violates

That's what the <set-property> element is for:

    <action path="..." ...>
      <set-property property="processAction" value="yadda yadda"/>
    </action>

This little trick lets you extend the syntax of an ActionMapping, and add
new configurable properties, without having to modify the DTD.
