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.
My advices for those who are going to sit that exam:
1). Read a book: 'Enterprise JavaBeans 3.1, 6th Edition - O'Reilly Media' by Rubinger and Burke. It is a good source of knowledge and covers lots of exam topics however it is not written especially for the exam. Read it carefully because there is some subtle information hidden and it can be important from the exam point of view.
