ForwardAction
Introduction:
ForwardAction acts as bridge from the current view and pages it link to.ForwardAction uses the RequestDispatcher to forward to a specified web resource.This allow you to link to an action instead of directly to a jsp.
Descriptions:
The ForwardAction class is useful when you’re trying to integrate Struts into an existing application that uses Servlets to perform business logic functions. ForwardAction used to forward a request to another resource in your application, such as a Servlet that already does business logic processing or even another JSP page.
Following step are required in ForwardAction :-
Create the html:link tag with the action attrributes ,add a link to the jsp pages that points to the action.
<html:link action="home">Login </html:link>
Create an action mapping that uses the ForwardAction with teh parameter attributes to specify the jsp pages.
