63 You are building a web application with a scheduling component. On the JSP, you need to show the current date, the date of the previous week, and the date of the next week. To help you present this information, you have created the following EL functions in the 'd' namespace: * Name : curData; signature: java.util.utilDate CurrentDate() * Name : curData; signature: java.util.utilDate addweek (java.util.Date, int) * Name: dateString; signature: java.util.String getDataString (jave.util.Data) Which EL code snippet will generate the string for the previous week? (A) ${d:dateString(affWeek(curDate(), -1)) } (B) ${d:dateString [addWeek[curDate[], - ]] } (C) ${d:dateString [d:addWeek[d:curDate[], - 1]] } (D) ${d:dateString (d:addWeek(d:curDate(), -1)) }

Which of the following deployment descriptor, web.xml, snippets correspond to the web fragment processing orders of X, Y, Z? (i) ＜absolute-ordering＞ ＜name＞X＜/name＞ ＜name＞Y＜/name＞ ＜name＞Z＜/name＞ ＜/absolute-ordering＞ (ii) ＜absolute-ordering＞ ＜name＞X＜/name＞ ＜name＞Y＜/name＞ ＜/absolute-ordering＞ (iii) ＜absolute-ordering＞ ＜/others＞ ＜name＞Y＜/name＞ ＜name＞Z＜/name＞ ＜/absolute-ordering＞ (iv) ＜absolute-ordering＞ ＜name＞X＜/name＞ ＜/others＞ ＜name＞Z＜/name＞ ＜/absolute-ordering＞ (v) ＜absolute-ordering＞ ＜name＞X＜/name＞ ＜name＞Y＜/name＞ ＜/others＞ ＜/absolute-ordering＞ (A) (i) only (B) (i) and (ii) (C) (i) and (iv) (D) (i), (iii), (iv) and (v)

複選題66 A session-scoped attribute is stored by a servlet, and then servlet forwards to a JSP page. Which three jsp:useBean attributes must be used to access this attribute in the JSP page? (Choose IT Certification Guaranteed, The Easy Way! 25 three.) (A) id (B) name (C) bean (D) type (E) scope F. beanName

複選題67 The Squeaky Beans Inc. shopping application was initially developed for a non-distributed environment. The company recently purchased the Acme Application Server, which supports distributed Httpsession objects. When deploying the application to the server, the doployer marks it as distributable in the web application deployment descriptor to take advantage of this feature. Given this scenario, which two must be true? (Choose two) (A) The J2EE web container must support migration of objects that implement serializable. (B) The J2EE web container must use the native JVM Serialization mechanism for distributing HttpSesaion objects. (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.

70 Which of the following annotations relate to security in a servlet? (i) @WebSecurity (ii) @RolesAllowed (iii) @WebConstraint (iv) @HttpConstraint (v) @Servletsecurity (A) (i) only (B) (i) and (iii) (C) (iv) and (v) (D) (iii) and (v) (E) (ii) and (iv)

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＞

73 Click the Exhibit button. Given the HTML form: 1. ＜html＞ 2. ＜body＞ 3. ＜form action="submit.jsp"＞ 4. Name: ＜input type="text" name="i1"＞＜br＞ 5. Price: ＜input type="text" name="i2"＞＜br＞ 6. ＜input type="submit"＞ 7. ＜/form＞ 8. ＜/body＞ 9. ＜/html＞ Assume the product attribute does NOT yet exist in any scope. Which code snippet, in submit.jsp, instantiates an instance of com.example.Product that contains the results of the form submission? (A) ＜jsp:useBean id="com.example.Product" /＞＜jsp:setProperty name="product" property="*" /＞ (B) ＜jsp:useBean id="product" class="com.example.Product" /＞${product.name = param.i1}${product.price = param.i2} (C) ＜jsp:useBean id="product" class="com.example.Product"＞＜jsp:setProperty name="product" property="name"param="i1" /＞＜jsp:setProperty name="product" property="price"param="i2" /＞＜/jsp:useBean＞ (D) ＜jsp:useBean id="product" type="com.example.Product"＞＜jsp:setProperty name="product" property="name"value="＜%= request.getParameter( "i1" ) %＞" /＞＜jsp:setProperty name="product" property="price"value="＜%= request.getParameter( "i2" ) %＞" /＞＜/jsp:useBean＞

74 You are creating a JSP page to display a collection of data. This data can be displayed in several different ways so the architect on your project decided to create a generic servlet that generates a comma delimited string so that various pages can render the data in different ways. This  servlet takes on request parameter: objoctID Assume that this servlet is mapped to the URL pattern: /WEB-INF/data. In the JSP you are creating, you need to split this string into its elements separated by commas and generate an HTML ＜ul＞ list from the data. Which JSTL code snippet will accomplish this goal? (A)＜c:import varReader='dataString' url='/WEB-INF/data'＞＜c:param name='objectID' value='${currentOID}' /＞＜/c:import＞＜ul＞＜c:forTokens items'${dataString.split(",")}' var='item'＞＜li＞ ${item}＜/li＞＜/c:forTokens＞＜/ul＞ (B)＜c:import varReader='dataString' url='/WEB-INF/data'＞＜c:param name='objectID' value='${currentOID}' /＞＜/c:import＞＜ul＞＜c:forTokens items'${dataString}' delims=',' var='item'＞＜li＞${item}＜/li＞＜/c:forTokens＞＜/ul＞ (C)＜c:import var='dataString' url='/WEB-INF/data'＞＜c:param name='objectID' value='${currentOID}' /＞＜/c:import＞＜ul＞＜c:forTokens items'${dataString.split(",")}' var='item'＞＜li＞${item}＜/li＞＜/c:forTokens＞＜/ul＞ (D)＜c:import var='dataString' url='/WEB-INF/data'＞＜c:param name='objectID' value='${currentOID}' /＞＜/c:import＞＜ul＞＜c:forTokens items'${dataString}' delims=',' var='item'＞＜li＞${item}＜/li＞＜/c:forTokens＞＜/ul＞

75 A developer wants to make a name attribute available to all servlets associated with a particular user, across multiple requests from that user, from the same browser instance. Which two provide this capability from within a tag handler? (Choose two) (A) pageContext.setAttribute("name", theValue); (B) pageContext.setAttribute("name", getSession() ); (C) pageContext.getRequest().setAttribute("name", theValue); (D) pageContext.getSession().setAttribute("name", theValue); (E) pageContext.setAttribute("name", theValue, PageContext.PAGE_SCOPE);
