A servlet context listener loads a list of com.example.Product objects from a database and stores that list into the catalog attribute of the ServletContext object.
Place code snippets to construct a jsp:useBean standard action to access this catalog.

Your web application requires the adding and deleting of many session attributes during a complex use case. A bug report has come in that indicates that an important session attribute is being deleted too soon and a NullPointerException is being thrown several interactions after the fact. You have decided to create a session event listener that will log when attributes are being deleted so you can track down when the attribute is erroneously being deleted.
Which listener class will accomplish this debugging goal?

• A. Create an HttpSessionAttributeListener class and implement the attributeRemoved method and log the attribute name using the getName method on the event object.
• B. Create an SessionAttributeListener class and implement the attributeRemoved method and log the attribute name using the getAttributeName method on the event object.
• C. Create an HttpSessionAttributeListener class and implement the attributeDeleted method and log the attribute name using the getName method on the event object.
• D. Create an SessionAttributeListener class and implement the attributeDeleted method and log the attribute name using the getAttributeName method on the event object.

What is true about Java EE authentication mechanisms?

• A. If you want your web application to support the widest possible array of browsers, and you want to perform authentication, the best choice of Java EE authentication mechanisms is DIGEST.
• B. To use Java EE FORM authentication, you must declare two HTML files in your deployment descriptor, and you must use a predefined action in the HTML file that handles your user's login.
• C. If your deployment descriptor correctly declares an authentication type of
  CLIENT_CERT, your users must have a certificate from an official source before they can use your application.
• D. If your deployment descriptor correctly declares an authentication type of BASIC, the container automatically requests a user name and password whenever a user starts a new session.

A developer is designing the presentation tier for a web application that relies on a complex session bean. The session bean is still being developed and the APIs for it are NOT finalized. Any changes to the session bean API directly impacts the development of the presentation tier. Which design pattern provides a means to manage the uncertainty in the
API?

• A. Front Controller
• B. Chain of Responsibility
• C. Business Delegate
• D. Composite View
• E. Intercepting Filter

Your company has a corporate policy that prohibits storing a customer's credit card number in any corporate database. However, users have complained that they do NOT want to re- enter their credit card number for each transaction. Your management has decided to use client-side cookies to record the user's credit card number for 120 days. Furthermore, they also want to protect this information during transit from the web browser to the web container; so the cookie must only be transmitted over HTTPS.
Which code snippet creates the "creditCard" cookie and adds it to the out going response to be stored on the user's web browser?

• A. 10. Cookie c = new Cookie("creditCard", usersCard);
  1 1. c.setHttps(true);
  1 2. c.setMaxAge(10368000);
  1 3. response.setCookie(c);
• B. 10. Cookie c = new Cookie("creditCard", usersCard);
  1 1. c.setSecure(true);
  1 2. c.setAge(10368000);
  1 3. response.setCookie(c);
• C. 10. Cookie c = new Cookie("creditCard", usersCard);
  11. c.setHttps(true);
  12. c.setAge(10368000);
  13. response.addCookie(c);
• D. 10. Cookie c = new Cookie("creditCard", usersCard);
  1 1. c.setSecure(true);
  1 2. c.setMaxAge(10368000);
  1 3. response.addCookie(c);
• E. 10. Cookie c = new Cookie("creditCard", usersCard);
  1 1. c.setSecure(true);
  1 2. c.setAge(10368000);
  1 3. response.addCookie(c);
