This week's book giveaways are in the Cloud and AI/ML forums. We're giving away four copies each of Cloud Native Patterns and Natural Language Processing and have the authors on-line! See this thread and this one 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.
