i am currently preparing for scwcd with HFSJ (its a wonderful book.)
i am having plans to focus on this technology with some more reference books.
(try some projects , i kind of like this tech.)
So in that case , will your book be useful for me or else its going to be study the same concepts again.
and how well are the specs covered in your book ?
Feel great to ask a question to the author himself!!!
Judging by feedback we've had from readers who started with HFSJ like yourself, I think you'd find my book helpful to enhance the concepts you've covered in HFSJ. As Marc mentioned in the bunkhouse review, my book makes a concise reference too, and adheres fairly completely to the specifications as mentioned in the 3 Steps to Success review (see Step 2).
It also has a couple of chapters on the new things in Java EE 5, and a few pages on prospective changes in the forthcoming Java EE 6, so with my book you can update your knowledge past the J2EE 1.4 specifications used in the current SCWCD exam.
