This week's book giveaway is in the OCAJP 8 forum. We're giving away four copies of OCA Java SE 8 Programmer I Study Guide and have Edward Finegan & Robert Liguori on-line! See this thread for details.
It might help you one day if you happen to work on a project still using EJB2.x. But I'd like to say that it's a good idea to know the content of a book before buying it. You should have ask here in the first place ;)
You'll find books that you can use for the exam here.
