From the introduction... Controller: Controller is intermediary between Model and View. Controller is responsible for receiving the request from client. Once request is received from client it executes the appropriate business logic from the Model and then produce the output to the user using the View component. ActionServlet, Action, ActionForm and struts-config.xml are the part of Controller.
From this page.. What is Action Class? The Action Class is part of the Model and is a wrapper around the business logic.
