Where should the jar file be placed inside the web application to ensure the resources it contains are accessible by clients? (A) WEB-INF/classes (B) WEB-INF/jar (C) WEB-INF/lib (D) WEB INF/resources

(A) httpServletRequest.isUserInRole("MANAGER"); (B) httpServletRequest.isCallerInRole("MANAGER"); (C) httpServletRequest.isPrincipalInRole("MANAGER"); (D) httpServletRequest.isAuthnticatedUserInRole("MANAGER");

39 You need to create a servlet filter that stores all request headers to a database for all requests to the web application's home page "/index.jsp". Which HttpServletRequest method allows you to retrieve all of the request headers? (A) String[] getHeaderNames () (B) String[] getRequestHeaders () (C) java.util.Iterator getHeaderNames () (D) java.util.Iterator getRequestHeaders () (E) java.util.Enumeration getHeaderNames () F. java.util.Enumeration getRequestHeaders ()

複選題41 Given an HttpServletRequest request:  22. String id = request.getParameter("jsessionid"); 23. // insert code here  24. String name = (String) session.getAttribute("name") Which three can be placed at line 23 to retrieve an existing HttpSession object?

42 You have built a web application that you license to small businesses. The webapp uses a context parameter, called licenseExtension, which enables certain advanced features based on your client's license package. When a client pays for a specific service, you provide them with a license extension key that they insert into the ＜context-param＞ of the deployment descriptor. Not every client will have this context parameter so you need to create a context listener to set up a default value in the licenseExtension parameter. Which code snippet will accomplish this goal? (A) You cannot do this because context parameters CANNOT be altered programmatically. (B) String ext = context.getParameter('licenseExtension');if ( ext == null ) { context.setParameter('licenseExtension' DEFAULT);} (C) String ext = context.getAttribute('licenseExtension');if ( ext == null ) { context.setAttribute('licenseExtension' DEFAULT);} (D) String ext = context.getInitParameter('licenseExtension')if ( ext == null ) { context.resetInitParameter('licenseExtension' DEFAULT);} (E) String ext = context.getInitParameter('licenseExtension')if ( ext == null ) { context.setInitParameter('licenseExtension' DEFAULT);}

複選題43 You have been contracted to create a web site for a free dating service. One feature is the ability for one client to send a message to another client, which is displayed in the latter client's private page. Your contract explicitly states that security is a high priority. Therefore, you need to prevent cross-site hacking in which one user inserts JavaScript code that is then rendered and invoked when another user views that content. Which two JSTL code snippets will prevent cross-site hacking in the scenario above? (Choose two.) IT Certification Guaranteed, The Easy Way! 17 (A) ＜c:out＞${message}＜/c:out＞ (B) ＜c:out value= '${message}' /＞ (C) ＜c:out value= '${message}' escapeXMl= 'true' /＞ (D) ＜c:out eliminateXml= 'true'＞${message}＜/c:out＞ (E) ＜c:out value='${message}' eliminateXml= 'true' /＞

44 When using Servlet asynchronous API if you want to dispatch the request back to a particular url - "url" within the same ServletContext which of the following API would you use? (A) AsyncContext.dispatch(); (B) AsyncContext.dispatch("/url"); (C) AsyncContext.dispatch(servletContext, "/url"); (D) AsyncContext.start(runnable); (E) RequestDispatcher.forward("/url"); F. RequestDispatcher.forward(servletContext, "/url"); G. RequestDispatcher.include("/url");
