Hi Ranchers,

I am planning to take Java EE 6 Java Persistence API Developer Certified Expert Exam in may.
I have started preparing for it with Pro Jpa 2 Mastering the java persistence API book.

In oracle website it is mentioned as " Oracle Certified JPA Developers for the Java EE6 Platform should have the knowledge required to build robust back-end functionality using Enterprise JavaBeans (EJB[TM]) version 3.1 technology. They are familiar with the EJB technology coding experience of session beans and message driven-beans ".

But the exam objectives doesnt contain any subject related to EJB.

Is EJB knowledge needed to clear Java EE 6 Java Persistence API Developer Certified Expert Exam ? currently i dont have any knowledge in EJB.
so can i take this exam ?

I am confused with this Please help me.

Transaction semantics span between the two exams. You are required to know Transactions Demarcations and Propagation. It forms almost 15% of the exam. You also need to know how to integrate JPA with the EJBs. But the spec covers everything you need for the exam. You need to know what type of Persistence Context used in Stateful or in Stateless session beans for example. You need just a ground-up knowledge of EJBs, I must. The section for Handling Exceptions also always sneaks in between the two exams.

What Jakachira said is correct. You need to know how to handle transactions (with the help of EntityManager API) and how to handle persistence context and units in EJBs. There may be few transaction related exception questions.

Thanks so much Jakachira and abraham. Your inputs are so valuable.

currently am using Pro Jpa 2 Mastering the java persistence API book to study and it also contains a chapter dedicated to EJB 3.1.
So is this book enough to cover EJB topics that i need know for exam ?

Also i came to know about this book from posts in javaranch. But those posts are old, dated back to 2011.
Is there any additional materials like new books or websites containing more useful info about JPA exam available now?

Hello Arun

I am not sure about how this book covers exam objectives related to EJB, however it is good for JPA stuffs.
