This week's book giveaway is in the OCAJP forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide 1Z0-808 and have Jeanne Boyarsky & Scott Selikoff 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.
