What is an ActionMapping?
An ActionMapping object describes an Action instance to the ActionServlet. It represents the information that uniquely defines an instance of a particular action class. The values defined by an ActionMapping object are what make a particular <action> definition unique.
The ActionMapping object also provides useful information to the Action.execute() method, giving an Action object the ability to alter its behaviour based on the values describing a particular ActionMapping instance. The signature of the Action.execute() method:

public ActionForward execute(ActionMapping mapping, ActionForm form, HttpServletRequest request, HttpServletResponse response){//some code here}
