The ForwardAction class is useful when you’re trying to integrate Struts into an existing application that uses Servlets to perform business logic functions. You can use this class to take benefit of the Struts controller and its functionality, without having to rewrite the existing Servlets. Use ForwardAction to forward a request to one more resource in your application, like a Servlet that already does business logic processing or even another JSP page. By using this predefined action, you don’t have to write your own Action class. You just have to set up the struts-config file properly to use ForwardAction.
