Hi,
firstly look
at the scea books page.
Personally I used
* Sun Certified Enterprise Architect for
J2EE Technology by Mark Cade and Simon Roberts
* UML Distilled Third Edition by Martin Fowler
* Design
Patterns by Erich Gamma, et al
* Core J2EE Patterns: Best Practices and Design Strategies, Second Edition by Deepak Alur et al
Out of the 4 I used the Cade and Roberts book a lot, the Martin Fowler book a bit, the Erich Gamma et al book a bit and the Deepak Alur et al book hardly at all.
I already had a copy of the last 3 books, if I did not then I probably would not have bought them just for the exam.
As an aside Core J2EE Patterns book is available electronically from the sun Web Site
here just click on a pattern for the description of the pattern.
