They are useful for what they cover. You'll need to supplement them for version 6 specific topics though. Unfortunately, I haven't seen any books yet for version 8 of the exam.

Hi, Jeanne. Thanks for your information.
Do I need to know EJB and Java ServerFaces before I prepare for the exam ?
I know some GoF design patterns and I am taking the web service developer exam now. I assume knowing this may help a little bit.

YOu need to know EJB and JSF at a high level. What they are good for; pros and cons; how to design; etc. You do not need to know how to code them for the architect exam.
