Q. What is ForwardAction ?

Suppose you want to go from PageA.jsp to PageB.jsp in your Struts
application. The easy way of achieving this is to add a hyperlink in PageA.jsp as
follows:
<a href="PageB.jsp">Go to Page B</a>
or even better, as follows:
<html:link page="/PageB.jsp">Go to Page B</html:link>
However this violates the MVC spirit by directly accessing
the JSP.
Struts provides a built-in Action class called ForwardAction to address this
issue. With ForwardAction, the Struts Controller is still in the loop while
navigating from PageA to PageB. There are two steps involved in using the
ForwardAction. They are:
_ First, declare the PageA hyperlink that takes you to PageB as follows:
<html:link page="/gotoPageB.do">Go to Page B</html:link>
_ Next, add an ActionMapping in the Struts Config file as follows:
<action path="/gotoPageB"
parameter="/PageB.jsp"
type="org.apache.struts.actions.ForwardAction" />
