I, I have passed the SCEA exam last week. Thanks to everyone who works in the SCEA forum! Score: Part I : 97% (wrong answer in "Common Architectures") Part II-III : 87% (don't know where I have missed some points and sun unfortunately doesn't give you some info about it) To prepare for the exam I have read: Cade, Roberts : Sun Certified Enterprise Architect for J2EE Technology Study Guide (too expensive for what is actually in it, but gives you at least an overview what to study) Monson-Haefel : Enterprise Java Beans, 3rd Ed. Fowler, Scott : UML Distilled (short, but useful) GOF : Design Patterns (a must-read) http://my.execpc.com/~gopalan/jms/jms.html for JMS I studied about for about 8 weeks (in the evening, 2hrs a day) for part I and it took me about 6 evenings for the architecture task. Part I: You have to read a lot of text for most of the questions. I think it is better to read the possible answers first and then the text. That might save you some time.
