Answer / kartheeswari
There are many steps,
1. After getting the request from the client, the
ActionServlet invokes the goGet() or doPost() method, in
which there is a invokation of process() method.This method
desides the module.
2. Action servlet dispatches the request to RequestProcesor
class which does some core works of ActionServlet.Then
invokes the appropriate Action class.
3. Action class does main business logic and data accessing
(communicating with Moedl) thru execute() method and which
returns the ActionForward object.
4. In b/w the form field validations happens in form bean.
5. Depends upon the value of ActionForward object the view
is decided to display.(output)
4. Form bean is invoked for form field validation,

process of creating , invoking , destroying the servlet is
known as "life cycle of struts". here three methods are
involved
1.init() :
Total intialization part of servlet ll be there in this .
2.service() :
Actual Bussiness code ll be there in this method
3.destroy() :
just destroying the servlet .
