This week's book giveaway is in the Spring forum. We're giving away four copies of Java Persistence with Spring Data and Hibernate and have Cătălin Tudose on-line! See this thread for details.
While Cade gives a few sample questions, he is more of a study guide than a complete reference. The other book says it has more sample questions. But the reviews on Amazon are horrible and I haven't seen people in this forum referring to it. (I bought and read the Cade book).
You might consider buying the Cade book and suplementing it with a mock exam if you want more questions. I blogged about SCEA mock exams.
