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.getLastAccessedTime() - session.getCreationTime();
• C. session.getLastAccessedTime().getTime() - session.getCreationTime().getTime();
• D. session.getLastAccessed().getTime() - session.getCreationTime().getTime();
• E. session.getLastAccessed() - session.getCreationTime();
• F. session.getMaxInactiveInterval() - session.getCreationTime();

Every page of your web site must include a common set of navigation menus at the top of the page. This menu is static HTML and changes frequently, so you have decided to use JSP's static import mechanism. Which JSP code snippet accomplishes this goal?

• A. <%@ page include='/common/menu.html' %>
• B. <%@ page import='/common/menu.html' %>
• C. <%@ include file='/common/menu.html' %>
• D. <%@ import file='/common/menu.html' %>
• E. <%@ include page='/common/menu.html' %>
• F. <%@ import page='/common/menu.html' %>

Given the security constraint in a DD:
101.
<security-constraint>
102.
<web-resource-collection>
103.
<web-resource-name>Foo</web-resource-name>
104.
<url-pattern>/Bar/Baz/*</url-pattern>
105.
<http-method>POST</http-method>
106.
</web-resource-collection>
107.
<auth-constraint>
108.
<role-name>DEVELOPER</role-name>
109.
</auth-constraint>
110.
</security-constraint>
And given that "MANAGER" is a valid role-name, which four are true for this security constraint? (Choose four.)

• A. DEVELOPER can do only a POST on resources in the /Bar/Baz directory.
• B. MANAGER can do a TRACE on any resource in the /Bar/Baz directory.
• C. DEVELOPER can do a TRACE on any resource in the /Bar/Baz directory.
• D. DEVELOPER can do a GET on resources in the /Bar/Baz directory.
• E. MANAGER can do a GET on resources in the /Bar/Baz directory.
• F. MANAGER can do a POST on any resource in the /Bar/Baz directory.

All of your JSPs need to have a link that permits users to email the web master. This web application is licensed to many small businesses, each of which have a different email address for the web master. You have decided to use a context parameter that you specify in the deployment descriptor, like this:
42.
<context-param>
43.
<param-name>webmasterEmail</param-name>
44.
<param-value>[email protected]</param-value>
45.
</context-param>
Which JSP code snippet creates this email link?

• A. <a href='mailto:${initParam.webmasterEmail}'>contact us</a>
• B. <a href='mailto:${contextParam.webmasterEmail}'>contact us</a>
• C. <a href='mailto:${applicationScope.webmasterEmail}'>contact us</a>
• D. <a href='mailto:${contextInitParam.webmasterEmail}'>contact us</a>

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. <jsp:directive.page contentType='application/javascript' />
• B. <jsp:document contentType='application/javascript' />
• C. 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.
• D. <jsp:page contentType='application/javascript' />
• E. <%@ page contentType='application/javascript' %>
