NO.10 As a convenience feature, your web pages include an Ajax request every five minutes to a special
servlet that monitors the age of the user's session. The client-side JavaScript that handles the Ajax
callback displays a message on the screen as the session ages. The Ajax call does NOT pass any
cookies, but it passes the session ID in a request parameter called sessionID. In addition, assume that
your webapp keeps a hashmap of session objects by the ID. Here is a partial implementation of this
servlet:
10. public class SessionAgeServlet extends HttpServlet {
11. public void service(HttpServletRequest request, HttpServletResponse) throws IOException {
12. String sessionID = request.getParameter("sessionID");
13. HttpSession session = getSession(sessionID);
14. long age = // your code here
15. response.getWriter().print(age);
16. } ... // more code here
47. }
Which code snippet on line 14, will determine the age of the session?
A. session.getMaxInactiveInterval();
B. session.getLastAccessed().getTime() - session.getCreationTime().getTime();
C. session.getLastAccessedTime().getTime() - session.getCreationTime().getTime();
D. session.getLastAccessed() - session.getCreationTime();
E. session.getMaxInactiveInterval() - session.getCreationTime();

Which listener class will accomplish this debugging goal?
A. Create an HttpSessionAttributeListener class and implement the attributeDeleted method and log the
attribute name using the getName method on the event object.
B. Create an HttpSessionAttributeListener class and implement the attributeRemoved method and log the
attribute name using the getName method on the event object.
C. Create an SessionAttributeListener class and implement the attributeRemoved method and log the

NO.17 To take advantage of the capabilities of modern browsers that use web standards, such as XHTML and
CSS, your web application is being converted from simple JSP pages to JSP Document format. However,
one of your JSPs, /scripts/screenFunctions.jsp, generates a JavaScript file. This file is included in several
web forms to create screen-specific validation functions and are included in these pages with the
following statement:
10. <head>
11. <script src='/scripts/screenFunctions.jsp'
12. language='javascript'
13. type='application/javascript'> </script>
14. </head>
15. <!-- body of the web form -->
Which JSP code snippet declares that this JSP Document is a JavaScript file?
A. <%@ page contentType='application/javascript' %>
B. <jsp:page contentType='application/javascript' />
C. <jsp:document contentType='application/javascript' />
D. <jsp:directive.page contentType='application/javascript' />
E. No declaration is needed because the web form XHTML page already declares the MIME type of the
/scripts/screenFunctions.jsp file in the <script> tag.

NO.18 You are building a web application that will be used throughout the European Union; therefore, it
has significant internationalization requirements. You have been tasked to create a custom tag
that generates a message using the java.text.MessageFormat class. The tag will take the
resourceKey attribute and a variable number of argument attributes with the format, arg<N>. Here
is an example use of this tag and its output:
<t:message resourceKey='diskFileMsg' arg0='MyDisk' arg1='1247' />
generates:
The disk "MyDisk" contains 1247 file(s).
Which Simple tag class definition accomplishes this goal of handling a variable number of tag attributes?
A. public class MessageTag extends SimpleTagSupport
implements VariableAttributes {
private Map attributes = new HashMap();
public void setVariableAttribute(String uri,
String name, Object value) {
this.attributes.put(name, value);}
// more tag handler methods}

B. ShoppingListTag can find the child instances of ItemSimpleTag by calling super.getChildren() and
casting each to an ItemSimpleTag.
C. It is impossible for ItemSimpleTag and ShoppingListTag to find each other in a tag hierarchy because
one is a Simple tag and the other is a Classic tag.
D. ShoppingListTag can find the child instances of ItemSimpleTag by calling getChildren() on the

14.Your web site has many user-customizable features, for example font and color preferences on web
pages. Your IT department has already built a subsystem for user preferences using the Java
SE platform's lang.util.prefs package APIs, and you have been ordered to reuse this subsystem in your
web application. You need to create an event listener that constructs the preferences factory and stores it
in the application scope for later use. Furthermore, this factory requires that the URL to a database must
be declared in the deployment descriptor like this:
42. <context-param>
43. <param-name>prefsDbURL</param-name>
44. <param-value>
45. jdbc:pointbase:server://dbhost:4747/prefsDB

public void contextInitialized(ServletContextEvent e) {
ServletContext ctx = e.getContext();
String prefsURL = ctx.getParameter("prefsDbURL");
PreferencesFactory myFactory = makeFactory(prefsURL);
ctx.putAttribute("myPrefsFactory", myFactory);}
// more code here}
B. public class PrefsFactoryInitializer implements ServletContextListener {
public void contextCreated(ServletContext ctx) {
String prefsURL = ctx.getInitParameter("prefsDbURL");
PreferencesFactory myFactory = makeFactory(prefsURL);
ctx.setAttribute("myPrefsFactory", myFactory);}
// more code here}
C. public class PrefsFactoryInitializer implements ServletContextListener {
public void contextInitialized(ServletContextEvent e) {
ServletContext ctx = e.getServletContext();
String prefsURL = ctx.getInitParameter("prefsDbURL");

NO.22 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 varReader='dataString' url='/WEB-INF/data'
