Extending ActionConfig in Struts2

[Vinod Singh]

Hi All,

The Struts 1.x provides a facility to extend the ActionMapping by 
defining it in web.xml in following manner-

   <init-param>
       <param-name>mapping</param-name>
       <param-value>CustomActionMapping</param-value>
   </init-param>

In Struts 2.x I don't see anyway to extend ActionConfig.

The ActionConfig class is hard coded in addAction(...) method of 
com.opensymphony.xwork2.config.providers.XmlConfigurationProvider.

Can anyone guide me in extending ActionConfig, if I am missing something?

Thanks,

Vinod
