You're limiting the number of people who might help you by not posting
the excercise/problem you're having directly and instead only giving a
reference to a book the readers of your message may not have.
(Probably not, judging by the lack of responses so far.)

Please post details of the excercise, what you've tried, what happened
as a result (including any errors messages and stack traces as
appropriate), and what you expected should've happened.  This will
ensure people have all the required information to help you directly
without having to spend time hunting down material and/or having to
guess at or extract from you what problem(s) you're having.

Thanks

Walter
