• Question 15:

  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.

  D

• Question 16:

  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();
  F. session.getLastAccessedTime() - session.getCreationTime();
  F. session.getLastAccessedTime() - session.getCreationTime();

• Question 17:

• Question 18:

  Which statement is true about web container session management?

  A. Access to session-scoped attributes is guaranteed to be thread-safe by the web container.
  B. To activate URL rewriting, the developer must use the HttpServletResponse.setURLRewriting method.
  C. If the web application uses HTTPS, then the web container may use the data on the HTTPS request stream to identify the client.
  D. The JSESSIONID cookie is stored permanently on the client so that a user may return to the web application and the web container will rejoin that session.
  C. If the web application uses HTTPS, then the web container may use the data on the HTTPS request stream to identify the client.

• Question 19:

  For an HttpServletResponse response, which two create a custom header? (Choose two.)

  A. response.setHeader("X-MyHeader", "34");

  C. response.setHeader(new HttpHeader("X-MyHeader", "34"));
  D. response.addHeader(new HttpHeader("X-MyHeader", "34"));
  E. response.addHeader(new ServletHeader("X-MyHeader", "34"));
  F. response.setHeader(new ServletHeader("X-MyHeader", "34"));
  A. response.setHeader("X-MyHeader", "34");
  B. response.addHeader("X-MyHeader", "34");

• Question 20:

  You have built a web application with tight security. Several directories of your webapp are used for internal purposes and you have overridden the default servlet to send an HTTP 403 status code for any request that maps to one of these directories. During testing, the Quality Assurance director decided that they did NOT like seeing the bare response page generated by Firefox and Internet Explorer. The director recommended that the webapp should return a more user-friendly web page that has the same look-and- feel as the webapp plus links to the webapp's search engine. You have created this JSP page in the / WEB-INF/jsps/error403.jsp file. You do NOT want to alter the complex logic of the default servlet. How can you declare that the web container must send this JSP page whenever a 403 status is generated?

  A. 403/WEB-INF/jsps/error403.jsp
  B. 403/WEB-INF/jsps/error403.jsp
  C. 403/WEB- INF/jsps/error403.jsp
  D. 403/WEB- INF/jsps/error403.jsp
  C. 403/WEB- INF/jsps/error403.jsp
