• Question 31:

  You have a simple wpb application that has a single Front Controller servlet that dispatches to JSPs generate a variety of views. Several of these views require further database processing to retrieve the necessary order object using the orderID request parameter. To do this additional processing, you pass the request first to a servlet that is mapped to the URL pattern /WEB INF / retrieveOrder.do. in the deployment descriptor. This servlet takes two request parameters, the ordered and the jspID and the jspURL. It handles the database calls to retrieve and build the complex order objects and then it dispatches to the jspURL.

  Which code snippet in the Front Controller servlet dispatches the request to the order retrieval servlet?

  A. reques.setAttribute ("orderID", orderIS); request.setAttribute("jspURL", jspURL); = context.getRequestDispathcher ("/WEB INF / retrieveOrder.do"); view.forward(request, response)
  B. reques.setAttribute ("orderID", orderIS); request.setAttribute("jspURL", jspURL); Dispatcher view = request.getDispatcher (".WEB INF / retrieveOrder.do"); View.forwardRequest (request, response);
  C. String T= "/WEB INF / retrieveOrder.do?orderID = %dandjspURl = %s"; String url = String.format (T, ordered, jspURL); = context.getRequestDispatcher (url); View.forward (request, response) ;
  D. String T= "/WEB INF / retrieveOrder.do?orderID = %dandjspURl = %s"; String url = String.format (T, ordered, jspURL); = context.getRequestDispatcher (url); View.forwardRequest (request, response) ;
  C. String T= "/WEB INF / retrieveOrder.do?orderID = %dandjspURl = %s"; String url = String.format (T, ordered, jspURL); = context.getRequestDispatcher (url); View.forward (request, response) ;

  (i) The javax.annotation.Resource annotation is used to declare a reference to a resource. @Resource can decorate a class, a field, or a method.

  *

  (v) javax.servlet.annotation Annotation Type WebServlet

  Annotation used to declare a servlet.

  This annotation is processed by the container at deployment time, and the corresponding servlet made available at the specified URL patterns.

  Incorrect:

  * Not (II) : javax.annotation.PreDestroy Target: Method
