Hi All,

I'm preparing for the oracle jpa certification (cx-310-094 / iz0-898), but I cannot find any useful information
Could anybody who passed this exam share the experiences with us?
Does anybody know a mock exam for it?

Thank You

today pass OCP-JPAD.
http://www.epractizelabs.com/certification/sun/oce-jpa-exam-6.html - totally useless, didn't help me.
I used this book for preparation - http://www.apress.com/9781430219569 and spec:JSR-000317 JavaTM Persistence 2.0 (Final Release)
The exam was very difficult, there were a lot of question with very-very close answers. Without good mock exams it's very difficult to make high score, I pass with 76%, all my previous certs was >90%.

I can try)) The main problem that there no mock exams for. I didn't have problem with some special topic from exam, but questions were very deep into details(sorry for my English) So if you only read the book and don't have enough practice it is very difficult to pass the exam. There were a lot of practice question.
I think the book http://www.apress.com/9781430219569 cover all exam topics, but you have not only read, but code all examples by yourself.

p.s. for 80% from exam's questions I didn't have 100% correct answer, I mean it was 50-50% or this or this, it wasn't like OCE-EJBD exam there were a lot of simple theoretical questions with clear answers.

hi,
I've just passed the test today, it was quite tough, but ok.
The time was just enough, I didn't have to hurry.
Questions with lot of text, and code waste a lot of time, especially criteria query questions.

I used http://www.epractizelabs.com/certification/sun/oce-jpa-exam-6.html. It was only 26 GBP, so it was an ok deal.
It contains few questions which are similar to the real exams' questions, so for the questions it's worth.
But the program is absolutely useless, it has lot of bad answers, but currently the only mock exam in the market

I used the Pro JPA2 book, and the specification.

Regards,

Passed JPA exam today and you won't believe, but also "I pass with 76%, all my previous certs was >90%. " ))))))
Used:
1) Pro Jpa 2 Mastering the java persistence API (chapters 1-11)
2) http://www.epractizelabs.com/certification/sun/oce-jpa-exam-6.html
3) 2 weeks of preparation + 4 years experience with hibernate

Hints:
1) Many questions on mapping embeddables/entities using collections/maps.
2) Many questions on advanced relationship (chapter 10 in Pro Jpa 2)
3) a few questions on EJB transaction propagation(REQUIRED,REQUIRES_NEW,etc) in EJB beans
4) Many questions on locking

A few words about epractize simulator:
1) still have issues in some questions: question has nothing with explanation )) or have wrong answer
2) drag and drop : labels are truncated to 'customListener...'and it is hard to recognize is it a 'customListener1' or 'customListener2'.
3) Add more questions on 'mapping embeddables/entities using collections/maps'
4) Add the ability to iterate over the ALL questions!!!

–°onclusion:
'Pro Jpa 2 Mastering the java persistence API' (suggest to read it twice if you want a high score )+ epractizelabs simulator is enough to pass the exam.
Good luck!

Hello,

thank you all for sharing your experiences. I am also planning to take the test and started with the exam topics showed on the oracle pages.
What is the issue with this auction application:


-Introducing the Auction Application
--Describe the auction application
--Define the domain objects of the auction application
--Describe the implementation model for the auction system

Where can I find more information about that?
Do I have to do extra oracle education stuff (and pay for it)?
Is it relevant for the exam anyway?

I would glad to know...
Best greets
Dirk

The objectives posted on oracle seem short. Locking is not even listed. What other topics are part of the exam but not listed in the objectives?

I took the JPA Certification Exam today (1Z0-898) and got 84%

I started reviewing using the ProJPA book. I have no real experience using the Java Persistence Api so this book helped me kickstart my review. But the book alone is not enough. I opened the OpenJpa examples in my eclipse and started to play around with it. After getting a feel of how JPA works I used the simulation exam of Enthuware. I highly recommend Enthuware, the questions give you a very good idea of how you will be tested. Without this exam simulator and a good tutor, I wouldn't have made it.

Oh and another important note: The exam objectives in the oracle website are useless. There are topics included in the exam that were not listed in the objectives like Cache and Cascade

Hi. I recently passed the 1Z0-898 certification. For preparation I created the list of questions/answers, which helped me a lot while preparing. All the info I took from Pro JPA 2: Mastering the Java Persistence API book. I downloaded these questions to http://jpa-quiz.rhcloud.com/. Feel free to use it for preparation.

Another material that can be used as a resource to prepare for the certification exam ORACLE CERTIFIED EXPERT JEE 6 JPA is the following android app:
https://play.google.com/store/apps/details?id=org.jpaexam
It is basically a quiz about the JSR 317: Java Persistence API, Version 2.0 Final Release.
This app can be used as a resource in learning the JSR, but also for those who are preparing for certification, both in the initial period (to assess the challenge), as when more advanced (as a simulated pre-test).
This address the following topics: Entity Class, Persistent Fields and Properties, Access Type, Primary Keys and Entity Identity, Embeddable Classes, Collections of Embeddable Classes and Basic Types, Entity Relationships, inheritance, EntityManager, Entity Instance's Life Cycle, Persistence Context Lifetime, Locking and Concurrency, Entity Listeners and Callback Methods, Bean Validation and Query APIs

I'm prepping for JPA exam for quite a while now. I've read the right chapters of the Pro JPA 2 book and now I'm doing the EPractize labs mock exams. And I must say, the EPractize mock exam program would be great if it didn't have all those errors! I've tried to give them feedback with the feedback-tool inside the program but no result.

Let me give an example.

Question: Which statements are true when a developer maps abstract entity class A with concrete sub-classes B and C, using the single table per class hierargy strategy? (what is a single table per class strategy anyway?)
A) Instances of B and C are stored in the same table.
B) Columns that correspond to fields in A must be defined nullable.
C) Fields in A are stored in a different table than the fields declared in B and C.
D) Columns that correspond to fields in B and C must be defined nullable in the database.

As a matter of fact I don't believe any of the above are true, but the program says A and D are correct. And this is but one example.. and I'm not even talking about the many typo's (they typed 'Int' instead of 'int', so I choose it to be a wrong type for Id... answer not correct...). It's true that because of this error, it triggered me to search it up in the book and the specs, but it shouldn't be the case of course.

I just want to raise this. The JPA OCE Training lab is really really bad quality. Like the post above some answers are just plain wrong. Explanations are crap. In the question im looking at now the answers are mentioning tables that dont even appear on the question. I bought this for the Web Services exam and experienced the same thing, but i though maybe it would be better. Its not. Dont buy this program, use Enthuware. period.
