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.
Good luck with the Book! The book seems to have quintessential topics that many research on, for EAI. With many open source and commerical vendors in the market, a patterns book will defenitely help in deciding the right mix.
