This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
SCEA is quite different from other sun certifications. It really tests your concepts, and books can give you the knowledge only upto a certain point. After that you need to use your brain and internet for clearing your doubts. The books i am using are- Design Patterns by Gang of Four Core j2ee design patterns Enterprise Java Beans - RMH Mastering EJB - II edition Professional EJB 3.0 Mark Cade's Architect Book
Though most of the material is outdated for SCEA 5. But i am also looking for a book targeted at SCEA 5.0
