I'm going to prepare the first exam for this certification. Can anyone help me to get the right book?
Which is the better between Sun Certified Enterprise Architect for Java EE Study Guide (Exam 310-051): Study Guide Exam 310-051 (Certification Press) by Allen, Bambara and Sun Certified Enterprise Architect for Java EE Study Guide” (2nd Edition) by Cade, Sheil?
which exam are you planing on JEE5 or JEE6, everybody prefers Cade and Sheil but it's more like an outline, for EE6 there are new books, but all these books are good, i used them all.
my advice is if you don't have much experience of major areas like security, massaging first do some research perhaps start up tutorials and gain the basic idea, then go for the exam book, this will give you more control over the exam.
I'm not sure about a new study guide, but there are lot of books on JEE6 so you can get a basic idea on whats new JEE6, with regards to the study guides you have in hand, EJB is the main concern as i know, apart from Cade's book other books got the old version of EJB 2.1 but other content is very good, my suggestion is, better to get an idea on the main changes from JEE5 to JEE6 in the exam context, for the new changes use EE6 tutorial or some books and for other areas you can still use existing study guides.
The book was written for OCMJEA version 5. The assignment is same for both the versions and you will find some common topics in the multiple-choice exam. You may also wait for OCMJEA 6 book by Paul Allen to be released in August.
