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＞

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); 

複選題76 You want to create a valid directory structure for your Java EE web application, and your application uses tag files and a JAR file. Which three must be located directly in your WEB-INF directory (NOT in a subdirectory of WEB-INF)? (Choose three.) (A) The JAR file (B) A directory called lib (C) A directory called tags (D) A directory called TLDs (E) A directory called classes F. A directory called META-INF

複選題77 Given that a web application consists of two HttpServlet classes, ServletA and ServletB, and the ServerletA service method:  20. String key = "com.example.data";  21. session.setAttribute(key, "Hello");  22. object value = session.getAttribute(key);  23. Assume session is an HttpSession, and is not referenced anywhere else in Servlet A Which two changes, taken together, ensure that value is equal to "Hello" on line 23? (Choose two) (A)ensure that the Servlet Bservice method is synchronized (B)ensure that the Servlet A service method is synchronized (C)ensure that Servlet B synchronizes on the session object when setting session attributes (D)enclose lines 21-22 in synchronized block:synchronized(this) (session.setAttribute(key, "Hello");value = session.getAttribute(key);) (E) enclose lines 21-22 in synchronized block:synchronized(session) (session.setAttribute(key, "Hello");value = session.getAttribute(key);)
