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? (Choose three) (A) HttpSession session = request.getSession(); (B) HttpSession session = request.getSession(id); (C) HttpSession session = request.getSession(true); (D) HttpSession session = request.getSession(false); (E) HttpSession session = request.getSession("jsessionid");

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");

45 Your web page includes a Java SE v1.5 applet with the following declaration: Which HTTP method is used to retrieve the applet code? (A) GET (B) PUT (C) POST (D) RETRIEVE

46 Which method must be used to encode a URL passed as an argument to HttpServletResponse. sendRedirect when using URL rewriting for session tracking? (A) ServletResponse.encodeURL (B) HttpServletResponse.encodeURL (C) ServletResponse.encodeRedirectURL (D) HttpServletResponse.encodeRedirectURL

47 A web browser need NOT always perform a complete request for a particular page that it suspects might NOT have changed. The HTTP specification provides a mechanism for the browser to retrieve only a partial response from the web server; this response includes information, such as the Last-Modified date but NOT the body of the page. Which HTTP method will the browser use to retrieve such a partial response? IT Certification Guaranteed, The Easy Way! (A) GET (B) ASK (C) SEND (D) HEAD (E) TRACE (F) OPTIONS

複選題48 View the Exhibit. Assume the product attribute does NOT yet exist in any scope. Which two create an instance of com.example.Product and initialize the name and price properties to the name and price request parameters? (Choose two) (A) ＜jsp:useBean id="product" class="com.example.Product" /＞＜jsp:setProperty name="product" property="*" /＞ (B) ＜jsp:useBean id="product" class="com.example.Product" /＞＜% product.setName( request.getParameter( "name" ) ); %＞＜% product.setPrice( request.getParameter( "price" ) ); %＞ (C) ＜jsp:useBean id="product" class="com.example.Product" /＞＜jsp:setProperty name="product" property="name"value="${param.name}" /＞＜jsp:setProperty name="product" property="price"value="${param.price}" /＞ IT Certification Guaranteed, The Easy Way! (D) ＜jsp:useBean id="product" class="com.example.Product"＞＜jsp:setProperty name="product" property="name"value="${name}" /＞＜jsp:setProperty name="product" property="price"value="${price}" /＞＜/jsp:useBean＞

49 A web component accesses a local EJB session bean with a component interface of com.example.Account with a home interface of com.example.AccountHome and a JNDI reference of ejb/Account. Which makes the local EJB component accessible to the web components in the web application deployment descriptor? (A) Option A (B) Option B IT Certification Guaranteed, The Easy Way! (C) Option C (D) Option D

50. Servlet A forwarded a request to servlet B using the forward method of RequestDispatcher. What attribute in B's request object contains the URI of the original request received by servlet A? (A) REQUEST_URI (B) javax.servlet.forward.request_uri (C) javax.servlet.forward.REQUEST_URI (D) javax.servlet.request_dispatcher.request_uri (E) javax.servlet.request_dispatcher.REQUEST_URI
