HFSJ Mock exam for chapter 5

[Sherif Mahmoud]

Hi,

I was solving the mock exam for chapter 5 of Head First Servlet and JSP. I doubt there might be a typo in question 6 answer.

The question asks to choose the true statements about listeners in javax.servlet package. The solution showed that option B is correct.

Here is what option B says:

"An HttpSessionListener can be used to perform an action when HttpSession has timed out."

I think it's a typo because HttpSessionListener is injavax.servlet.http package not javax.servlet

Thanks,

Sherif

Yes you are right, it's an error :-)

I looked in the book errata on the o'reilly web site. It lists this as an error and the correction is to remove the part that specifies that the listeners should be in javax.servlet package.

Thanks,

Sherif
