Answer / cokekrish
The class org.apache.struts.action.ActionServlet is called
ActionServlet.This class plays the role of controller. All
the requests to the server goes thorugh the controller. It
is responsible for handling all the requests.
Action is part of Model. The purupose of Actionclass is to
translate the HttpServletRequest to the business logic. To
use Action we need to subclass and overwrite the execute()
method. all database and business processing are done here.

Most of whats said is correct...

ActionServlet.This class plays the role of controller. All
the requests to the server goes thorugh the controller. It
is responsible for handling all the requests.
----> (Action is part of Model.) --> Its still a part of
controller as it directs you to the appropriate business
processor class (which is a part of model).
The purupose of Actionclass is to
translate the HttpServletRequest to the business logic. To
use Action we need to subclass and over(RID)e the execute()
method.
all database and business processing are done here. -->
These CAN be done here, but shouldn't as it would defeat the
purpose of having a seperate Model layer i.e. Business
Layer. The request must be directed to a business class
which would process the request, perform the neccesary
Database operations if any, wrap the response in a response
object and send it back to the action class to be directed
to the next view by means of mapping.findForward...
Thats my take on this...

receive the request.this is initial starting point to the
communication and justify the purpose of the communication

where we provide the user defined controller logical
transactions which allways listen to actionservlet.
