I don't know if this topic already exist but I'd like to point out errors in Charles Lyons book.

Chapter 8 - Revision questions - question 3 : The correct answer is supposed to be " C " but ServletRequest.newAsync() do not even exist.

or maybe I'm wrong and I do not understand something ?

Yes, of course, you are right.
In fact, there is no correct answer listed in the book for this question.
The correct method name is "startAsync()", but it is declared in ServletRequest interface (and not in ServletContext as in answer "B")

I'm still reading the book, and in general I'm pretty satisfied with it.
Author definitely is good one and knows what he is talking about.

But the big number of typos is annoying. Wait till chapter 11 where even number of correct answers of several questions is wrong.

And support from the official site of publisher - is pathetic.
In fact there is no such - Third Edition of the book is not listed there, so no errata, no download bundle, nothing ...

P.S.: OK, to be fair, download bundle of Second Edition is available, but ... why? is it so difficult just to upload and host one war file?

I am currently studying this book. I have just finshed chapter 17.

I agree with Jim that Charles Lyons is a briliant writer, who knows what he is talking about.

I also agree with Jim that the support from the publisher leaves much to be desired!
But in all fairness I have to point out that they did publish a first version of an errata list on their site.

To Sebastian: the error you asked about, actually is corrected on that errata list.

I have posted several errata reports over the last 6 weeks, but the errata list isn't updated yet.
And I find it strange that there isn't any corrections regarding the last half of the book.

Now one final issue regarding the JSP part of the book:
I have assumed that the exam will assess my knowledge of JSP 2.2 (JSR 245 as of 2009-12-10).
But the book sticks strictly to JSP 2.0 (JSR 152 as of 2003-11-24).
Do you think this is really a problem, or can I just relax on that ?
