In a JSP-centric web application, you need to create a catalog browsing JSP page. The catalog is stored as a List object in the catalog attribute of the webapp's ServletContext object. Which scriptlet code snippet gives you access to the catalog object?

B. <% List catalog = context.getAttribute("catalog"); %>

C. <% List catalog = application.getAttribute("catalog"); %>

D. <% List catalog = servletContext.getAttribute("catalog"); %>

Assume that a news tag library contains the tags lookup and item:

lookup Retrieves the latest news headlines and executes the tag body once for each headline. Exposes a NESTED page-scoped attribute called headline of type com.example.Headline containing details for that headline.

item Outputs the HTML for a single news headline. Accepts an attribute info of type com.example.Headline containing details for the headline to be rendered.Which snippet of JSP code returns the latest news headlines in an HTML table, one per row?

A. [table]

B. [table]

C. [table]

D. [table]

You have a simple web application that has a single Front Controller servlet that dispatches to JSPs to 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/retreiveOrder.do in the deployment descriptor. This servlet takes two request parameters, the orderID 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. request.setAttribute("orderID", orderID);request.setAttribute("jspURL", jspURL);RequestDispatcher view= context.getRequestDispatcher("/WEB- INF/retreiveOrder.do");view.forward(request, response);

B. request.setParameter("orderID", orderID);request.setParameter("jspURL", jspURL);Dispatcher view= request.getDispatcher("/WEB-INF/retreiveOrder.do");view.forwardRequest(request, response);

C. String T="/WEB-INF/retreiveOrder.do?orderID=%dandjspURL=%s";String url = String.format(T, orderID, jspURL);RequestDispatcher view= context.getRequestDispatcher(url);view.forward(request, response);

D. String T="/WEB-INF/retreiveOrder.do?orderID=%dandjspURL=%s";String url = String.format(T, orderID, jspURL);Dispatcher view= context.getDispatcher(url);view.forwardRequest(request, response);

Every page of your web site must include a common set of navigation menus at the top of the page. This menu is static HTML and changes frequently, so you have decided to use JSP's static import mechanism. Which JSP code snippet accomplishes this goal?

B. <%@ page import='/common/menu.html' %>

C. <%@ import page='/common/menu.html' %>

D. <%@ include file='/common/menu.html' %>

E. <%@ page include='/common/menu.html' %>

F. <%@ include page='/common/menu.html' %>

If you want to use the Java EE platform's built-in type of authentication that uses a custom HTML page for authentication, which two statements are true? (Choose two.)

A. Your deployment descriptor will need to contain this tag:CUSTOM.

B. The related custom HTML login page must be named loginPage.html.

C. When you use this type of authentication, SSL is turned on automatically.

D. You must have a tag in your deployment descriptor that allows you to point to both a login HTML page and an HTML page for handling any login errors.

E. In the HTML related to authentication for this application, you must use predefined variable names for the variables that store the user and password values.

You need to store a floating point number, called Tsquare, in the session scope. Which two code snippets allow you to retrieve this value? (Choose two.)

A. float Tsquare = session.getFloatAttribute("Tsquare");

B. float Tsquare = (Float) session.getAttribute("Tsquare");

C. float Tsquare = (float) session.getNumericAttribute("Tsquare");

D. float Tsquare = ((Float) session.getAttribute.("Tsquare")).floatValue();

E. float Tsquare = ((Float) session.getFloatAttribute.("Tsquare")).floatValue;

F. float Tsquare = ((Float) session.getNumericAttribute.("Tsquare")).floatValue;
