ActionMapper and ActionMapping objets

The ActionMapper fetches the ActionMapping object corresponding to a given request. Essentially, the ActionMapping is a data transfer object that collects together details such as the Action class and method to execute. The mapping is utilized by the Dispatcher and various user interface components. It is customizable through struts.mapper.class entry in struts.properties.

Customize

struts.mapper.class=foo.bar.MyCustomActionMapper

public class MyCustomActionMapper implements ActionMapper {
  public ActionMapping getMapping(HttpServletRequest request, 
                                  ConfigurationManager configManager) {
    ....
  }
