                                          Question 1

                                          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: objectID. 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 var='dataString' url='/WEB-INF/data'>
                                          <c:param name='objectID' value='${currentOID}' />
                                          </c:import>
                                          <ul>
                                          <c:forTokens items'${dataString.split(",")}' var='item'>
                                          <li>${item}</li>
                                          </c:forTokens>
                                          </ul>
                                          B. <c:import var='dataString' url='/WEB-INF/data'>
                                          <c:param name='objectID' value='${currentOID}' />
                                          </c:import>
                                          <ul>
                                          <c:forTokens items'${dataString}' delims=',' var='item'>
                                          <li>${item}</li>
                                          </c:forTokens>
                                          </ul>
                                          C. <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>${item}</li>
                                          </c:forTokens>
                                          </ul>
                                          D. <c:import varReader='dataString' url='/WEB-INF/data'>
                                          <c:param name='objectID' value='${currentOID}' />
                                          </c:import>
                                          <ul>
                                          <c:forTokens items'${dataString}' delims=',' var='item'>
                                          <li>${item}</li>

                                          </ul>

                                          B. when a session attribute value is changed
                                          C. when a session has timed out
                                          D. when a servlet has forwarded a request
                                          E. after a servlet is destroyed
                                          F. when a session is created


                                          Question 3

                                          Which two directives are applicable only to tag files? (Choose two.)

                                          C. variable
                                          D. taglib
                                          E. tag


                                          Question 4

                                          Assume a JavaBean com.example.GradedTestBean exists and has two attributes. The attribute name is of type java.lang.String and the attribute score is of type java.lang.Integer.
                                          An array of com.example.GradedTestBean objects is exposed to the page in a requestscoped attribute called results. Additionally, an empty java.util.HashMap called resultMap is placed in the page scope.
                                          A JSP page needs to add the first entry in results to resultMap, storing the name attribute of the bean as the key and the score attribute of the bean as the value.
                                          Which code snippet of JSTL code satisfies this requirement?

                                          A. ${resultMap[results[0].name] = results[0].score}
                                          B. <c:set var="resultMap" property="${results[0].name}"
                                          value="${results[0].score}" />
                                          C. <c:set target="${resultMap}" property="${results[0].name}"
                                          value="${results[0].score}" />
                                          D. <c:set var="resultMap" property="${results[0].name}">
                                          ${results[0].value}
                                          </c:set>
                                          E. <c:set var="${resultMap}" key="${results[0].name}"
                                          value="${results[0].score}" />


                                          Question 5

                                          Your management has required that all JSPs be created to generate XHTML-compliant content and to facilitate that decision, you are required to create all JSPs using the JSP Document format. In the reviewOrder.jspx page, you need to use several core JSTL tags to process the collection of order items in the customer's shopping cart. Which JSP code snippets must you use in the reviewOrder.jspx page?
