  • Question 133:

    Your web application views all have the same header, which includes the tag in the <head> element of the rendered HTML. You have decided to remove this redundant HTML code from your JSPs and put it into a single JSP called / WEB-INF/jsp/header.jsp. However, the title of each page is unique, so you have decided to use a variable called pageTitle to parameterize this in the header JSP, like this: </p><p>10. <title>${param.pageTitle}<title> </p><p>Which JSP code snippet should you use in your main view JSPs to insert the header and pass the pageTitle variable? </p><p>A. <jsp:insert page='/WEB-INF/jsp/header.jsp'>${pageTitle='Welcome Page'}</jsp:insert> </p><p>B. <jsp:include page='/WEB-INF/jsp/header.jsp'>${pageTitle='Welcome Page'}</jsp:include> </p><p>C. <jsp:include file='/WEB-INF/jsp/header.jsp'>${pageTitle='Welcome Page'}</jsp:include> </p><p>D. <jsp:insert page='/WEB-INF/jsp/header.jsp'><jsp:param name='pageTitle' value='Welcome Page' /></ jsp:insert> </p><p>E. <jsp:include page='/WEB-INF/jsp/header.jsp'><jsp:param name='pageTitle' value='Welcome Page' /></ jsp:include> </p></p> <div class="answer" id="answer2797047" style="display: none"><p>Correct Answer: E </p></div> <div class="button"> <input type="button" class="btn btn-primary answer-btn" value="SHOW ANSWERS" data-id="2797047"> </div> </li> <li> <h4>Question 134: </h4> <p><p>A JSP page needs to instantiate a JavaBean to be used by only that page.

Your IT department has already built a subsystem for user preferences using Java SE's lang.util.prefs package APIs and you have been ordered to reuse this subsystem in your web application. You need to create an event listener that stores the user's Preference object when an HTTP session is created. Also, note that user identification information is stored in an HTTP cookie. </p><p>Which partial listener class can accomplish this goal? </p><p>A. public class UserPrefLoader implements HttpSessionListener {public void sessionCreated (HttpSessionEvent se) {MyPrefsFactory myFactory = (MyPrefsFactory) se.getServletContext ().getAttribute("myPrefsFactory");User user = getUserFromCookie(se);myFactory.setThreadLocalUser (user);Preferences userPrefs = myFactory.userRoot();se.getSession().setAttribute("prefs", userPrefs);}// more code here} </p><p>B. public class UserPrefLoader implements SessionListener {public void sessionCreated(SessionEvent se) {MyPrefsFactory myFactory = (MyPrefsFactory) se.getContext().getAttribute("myPrefsFactory");User user = getUserFromCookie (se);myFactory.setThreadLocalUser(user);Preferences userPrefs = myFactory.userRoot ();se.getSession().addAttribute("prefs", userPrefs);}// more code here} </p><p>C. public class UserPrefLoader implements HttpSessionListener {public void sessionInitialized (HttpSessionEvent se) {MyPrefsFactory myFactory = (MyPrefsFactory) se.getServletContext ().getAttribute("myPrefsFactory");User user = getUserFromCookie(se);myFactory.setThreadLocalUser (user);Preferences userPrefs = myFactory.userRoot();se.getHttpSession().setAttribute("prefs", userPrefs);}// more code here} </p><p>D. public class UserPrefLoader implements SessionListener {public void sessionInitialized(SessionEvent se) {MyPrefsFactory myFactory = (MyPrefsFactory) se.getServletContext().getAttribute ("myPrefsFactory");User user = getUserFromCookie(se);myFactory.setThreadLocalUser (user);Preferences userPrefs = myFactory.userRoot();se.getSession().addAttribute("prefs", userPrefs);}// more code here} </p></p> <div class="answer" id="answer2797043" style="display: none"><p>Correct Answer: A </p></div> <div class="button"> <input type="button" class="btn btn-primary answer-btn" value="SHOW ANSWERS" data-id="2797043"> </div> </li> <li> <h4>Question 140: </h4> <p><p>You have a use case in your web application that adds several session-scoped attributes. At the end of the use case, one of these objects, the manager attribute, is removed and then it needs to decide which of the other session-scoped attributes to remove. </p><p>How can this goal be accomplished? </p><p>A. The object of the manager attribute should implement the HttpSessionBindingListener and it should call the removeAttribute method on the appropriate session attributes. </p><p>B. The object of the manager attribute should implement the HttpSessionListener and it should call the removeAttribute method on the appropriate session attributes. </p><p>C. The object of the manager attribute should implement the HttpSessionBindingListener and it should call the deleteAttribute method on the appropriate session attributes. </p><p>D.
