Hi all,

I feel confusing at the end of Chapter 6 mock questions:

Page 275:
Q4: Which of the following are NOT listener event types in J2EE 1.4 API?
A. HttpSessionEvent
B. ServletRequestEvent
C. HttpSessionBindingEvent
D. HttpSessionAttributeEvent
E. ServletContextAttributeEvent
My answers are B, D and E. But correct answer is only D. Why?

Q5: In B option, what is the word "SSL" mean?

Page 279:
Q15: I cannot understand the explanation for option C.

Can anybody help me out? Thanks alot.

Q4) Because if you look at the API, you'll find out that both B and E are correct.

Q5) I don't know what the question is, but SSL is used for secured communication (used with HTTPS).
