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.
Gilles, While the book is a good read in learning how things work, it is more for the concepts at this point. You still need an EJB 3.0 book as so much has changed in EJB. And the exam objectives to see what you should focus on.
