Question: 22<br />

A developer for the company web site has been told that users may turn off cookie support in their<br />

browsers. What must the developer do to ensure that these customers can still use the web<br />

application?<br />

APIs.<br />

B. The developer must provide an alternate mechanism for managing sessions and abandon the<br />

HttpSession mechanism entirely.<br />

Question: 23<br />

Your web application requires the adding and deleting of many session attributes during a complex<br />

use case. A bug report has come in that indicates that an important session attribute is being deleted<br />

too soon and a NullPointerException is being thrown several interactions after the fact. You have<br />

decided to create a session event listener that will log when attributes are being deleted so you can<br />

track down when the attribute is erroneously being deleted. Which listener class will accomplish this<br />

debugging goal?<br />

A. Create an HttpSessionAttributeListener class and implement the attributeDeleted method and<br />

log the attribute name using the getName method on the event object.<br />

B. Create an HttpSessionAttributeListener class and implement the attributeRemoved method and<br />

log the attribute name using the getName method on the event object.<br />

C. Create an SessionAttributeListener class and implement the attributeRemoved method and log<br />

the attribute name using the getAttributeName method on the event object.<br />

D. Create an SessionAttributeListener class and implement the attributeDeleted method and log<br />

the attribute name using the getAttributeName method on the event object.<br />

Answer: B<br />

Question: 24<br />

As a convenience feature, your web pages include an Ajax request every five minutes to a special<br />

servlet that monitors the age of the user's session. The client-side JavaScript that handles the Ajax<br />

callback displays a message on the screen as the session ages. The Ajax call does NOT pass any cookies,<br />
