Struts 2 has a concept of ActionMapper which maps URL request to specific action class using Java mapping instead of XML mapping. This can be created using setting one property in struts.xml as <ActionMapperKey>=<ActionMapperClass>. This mapper does not have <action> tag entry in struts.xml.
My requirement is that i have one existing ActionMapper class. I want to configure one interceptor on this mapper.
How can i add the interceptor to the ActionMapper.
