(C) As per the specification, the J2EE web container ensures that distributed Httpsassion objects will be stored in a database. (D) Storing references to Enterprise JavaBeans components in the HttpSession object might NOT supported by J2EE web contain.

71 A web application for business expense reporting allows uploading expense receipts. Multiple receipts can be uploaded single step using one HTTP request. The servlet that processes the request has been marked with the @MultipartConfig annotation. Which method should the servlet use to access the uploaded files? (A) HttpServletRequest.getParts() (B) HttpServletRequest.getData() IT Certification Guaranteed, The Easy Way! 27 (C) servletRequest.getParts() (D) servletRequest.getAllParts()

複選題Explanation The request.getParts() method returns collections of all Part objects. If you have more than one input of type file, multiple Part objects are returned. Since Part objects are named, the getPart(String name) method can be used to access a particular Part. Alternatively, the getParts() method, which returns an Iterable＜Part＞, can be used to get an Iterator over all the Part objects.72 Refer to the Exhibit. A servlet sets a session-scoped attribute product with an instance of com.example.product an forward to a JSP. Which two output the name of the product in the response? (Choose two) (A) ＜%= product.getName() %＞ IT Certification Guaranteed, The Easy Way! 28 (B) ＜jsp:useBean id="product" class="com.example.Product" /＞＜%= product.getName() %＞ (C) ＜jsp:useBean id="com.example.Product" scope="page"＞＜%= product.getName() %＞＜/jsp:useBean＞ (D) ＜jsp:useBean id="product" type="com.example.Product"scope="page" /＞＜%= product.getName() %＞ (E) ＜jsp:useBean id="product" type="com.example.Product"＞＜%= product.getName() %＞＜/jsp:useBean＞
