Discussion Board
ActionServlet and RequestProcessor

Servlet application is created in the following manner:

1) The user interface is created with server pages, which doesn't contain any business logic. These pages represent the "view" component of an MVC architecture.
2) Forms and hyperlinks in the user interface that require business logic to be executed will be submitted to a request URI that is mapped to this servlet.
3) There can be one instance of this servlet class, which receives and processes all requests that change the state of a user's interaction with the application. The servlet delegates the handling of a request to a RequestProcessor object. This component represents the "controller" component of an MVC architecture.
4) The RequestProcessor selects and invokes an Action class to perform the requested business logic, or delegates the response to another resource.

Out of the following options 1,2,4,5 matches the process that gets carried by ActionServlet and RequestProcessor.
