This week's book giveaway is in the OCPJP forum. We're giving away four copies of OCA/OCP Java SE 7 Programmer I & II Study Guide and have Kathy Sierra & Bert Bates on-line! See this thread for details.
Its a pretty good book and covers everything on the exam. Though IMO, you should also refer to Head First Servlets & JSP, since everyone preparing for this exam seems to be using it and have found it to be really useful.
