* <!-- START SNIPPET: description -->
* Prefix based factory should be used with {@link org.apache.struts2.dispatcher.mapper.PrefixBasedActionMapper}
* to use appropriate {@link com.opensymphony.xwork2.ActionProxyFactory} connected with given
* {@link org.apache.struts2.dispatcher.mapper.ActionMapper}
*
* Add below entry to struts.xml to enable the factory:
* &lt;constant name="struts.actionProxyFactory" value="prefix"/&gt;
*
* The factory will use the same set of patterns as defined with:
* &lt;constant name="struts.mapper.prefixMapping" value="..."/&gt;
