public class ForwardAction

extends Action

An Action that forwards to the context-relative URI specified by the parameter property of our associated ActionMapping. This can be used to integrate Struts with other business logic components that are implemented as servlets (or JSP pages), but still take advantage of the Struts controller servlet's functionality (such as processing of form beans).

To configure the use of this Action in your struts-config.xml file, create an entry like this:

<action path="/saveSubscription" type="org.apache.struts.actions.ForwardAction" name="subscriptionForm" scope="request" input="/subscription.jsp" parameter="/path/to/processing/servlet"/>

which will forward control to the context-relative URI specified by the parameter attribute.
