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.
I looked over the description for the book and it sounds very interesting. Does it contain any example code (that can be compiled and run) or does it mainly discuss the persistence technologies at a higher level?
