Hi everyone,

today I passed my JPA Certification exam!

There isnt't a book that prepares you specifically to this certification, but I used the resources suggested in this forum (thanks to all of you that shared your resources!):

- Pro JPA 2, 2009 edition: http://www.apress.com/9781430219569
There is a newer edition, but if you want to be more focused on the stuff that is tested on the exam, you can use the old version too, it's up to you.

- JPA 2.0 scecification: http://download.oracle.com/otn-pub/jcp/persistence-2.0-fr-oth-JSpec/persistence-2_0-final-spec.pdf
Don't be scared by the fact that is a specification, it is not so hard to read, and I think it's a must. In fact, I think that studying on Pro JPA 2 alone isn't enough.

- Enthuware test prep: http://enthuware.com/index.php/mock-exams/oracle-certified-expert/java-persistence-api-oce-jpa
Really useful, because it really goes into details about why some answers are correct or not, referring to the specifications.
Some question are very similar to the ones found in the real exam (maybe too similar).

I used MyExamCloud too, but I wouldn't suggest it, Enthuware product is much much better.

I think that preparing for this exam really helped me in improving my preparation on JPA.

Hi Luigi and for everyone who will take this exam,
Luigi mentioned the first edition of JPA Pro is useful for the example. I am using the second edition that covers JPA 2.1
I was wondering which chapter of JPA Pro to skip.

In chapter 11 of the first edition, there are examples are helpful for this exam:
nativeQueries, sqlInsertDelete, sqlResultSetMappings, idClassResultMapping, embeddedIdResultMapping, inheritanceResultMapping,
lifecycleCallback, lifecycelCallbackInheritance, constraints , validatorInjection, constraintGroups, constraintGroups, constraintAnnotation , entityRefresh...(these three examples are now in chapter 12).

In chapter 11 of the 2nd edition,   examples 07-22 : constructorResultMapping, storedProc, namedEntityGraphBasic, namedEntityGraphSubgraphs...
can be skipped as these examples are not covered in 1nd edition.

I am trying to figure out which specific examples/topics in 2nd edition that are not in 1st edition and I will skip them.

Hi all

Today i pass the JPA Cert with 89%. I share the input from Luigi. Enthuware is much better than the MyExamCloud. Enthuware and the JPA Specification is enough to pass it successfully.

Congratulations, Luigi and Peter!

I would love to know how this certification will be helping you.  I hold the EJB certification, but I skipped the JPA part of that.  I have played with JPA on a few projects (I particularly like how it has taken Criteria one step beyond what Hibernate had done).   But, I have never committed to getting that certification for JPA.

Why did you feel it was worth it?  Just 'for the challenge', is certainly reason enough, IMHO.  But did you see a market for that skill?

Thanks in Advance,

So far , as I know, some projects require  you to know JPA.
