What are the various steps involved in the implementaion of struts? 
The struts framwork models its server side implementation of the MVC using a combination of JSPs, custom JSP tags, and a Java Servlet. It involves the following steps :

  * The incoming request is received by the ActionServlet, which acts as the controller, and the ActionServlet looks up the requested URI in an XML file.
  * The ActionClass performs its logic on the Model components associated with the application.
  * Once the Action has completed its processing, it returns control to the ActionServlet with a key that indicates the result of its processing. ActionServlet uses this key to determine where this result should be forwarded for presentation.
  * The request is complete when the ActionServlet response by forwarding the request ot the view that was linked to the returned key, and this view presents the result of the Action.
