The time of publishment for the book is not that important, because SCDJWS is just released, and RMH is one of the exam team member, and he knows what version of what technologies are covered.
Instead, since some of the topics are not covered in RMH's book, like security, endpoint design, JAXB, etc, you may need to see whether the other book you have mentioned discussed about these issues. If not, I still recommend RMH, otherwise, you may consider using both.
RMH is the best according to the syllabus and the other book u could read for Topics which are not covered like JAXB endpoint design security etc. U need more then RMH in any case becuase u need the blueprints guide a definite read for the architecture aspect of webservice covered. HTH Dhiren
