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.
I would like to learn more about 3-tier architecture(presentation, business logic, data) programming in java. Does anybody know a good tutorial (or a book)? Especially tutorials about building a sample application would be very interesting.
