This week's book giveaway is in the OCMJEA forum. We're giving away four copies of OCM Java EE 6 Enterprise Architect Exam Guide and have Paul Allen & Joseph Bambara on-line! See this thread for details.
There's a separate site called SOABooks which is dedicated for those books. And of course there are many articles you can find by a simple search where you can learn the basics. Also you can various pointers and recommendations in our FAQ section.
