Hello sorry for the question, I know it could sounds repetive. I am planning to take Java EE 6 Java Persistence API Developer certification.
I have the book Pro JPA 2 Mastering (chaps 1 to 11 right ? ) and it really looks huge and tedious book to me :-)
I am wondering if
  • Java Persistence free online book
  • EE 6 JPA OCE Preparation Article
  • can substitute it.
    Actually I am great fan of enthuware mock, I have used it for programmer certification and I rely on it.
    About my studing methodology I like to read concept and stuck in my head writing code examples, is it eclipse and simple DB like mysql or postgres enough ?
    Anybody passed both JPA and WebServices wich is tougher ? wich differences ?
    thanks in advance
    Davide

    But it is one of the best book for JPA. I am also reading the same book for JPA Certification. Read some past experiences of peoples who have passed JPA Certification.

    is it eclipse and simple DB like mysql or postgres enough ?

    Ya, any basic relational database should be fine. I am using Apache Derby Database.

    Anybody passed both JPA and WebServices wich is tougher ? wich differences ?

    Difficult question to answer as both certification deals with altogether separate realm. Web Service exam talks about SOAP and REST web service where more focus is on building apps which can share data.
    JPA certification deals with how to store/retrieve/query Data from DB.
    So I think no comparison can be made. I do not have good hands with Java -DB interaction [ never worked on such integration before] so I am finding JPA exam prep to be difficult.

    in fact before reading this book, I started off with this Developer guide link http://www.objectdb.com/java/jpa
    I executed all code samples given in this link. I exclude all ObjectDB's specific deviation.

    Thanks a lot Abhay, I arrived a chapter 4 I dont find the topics very difficult but the book is so slow and slow probably I have no vocation for persistence and DB I am more volatile oriented :-) and this answer my question :-)
    I took java web services last year and I have found very interesting I took me 3 months to prepare, I have read a lot past messages about JPA here I have heard a guy ,he took 25 days to complete certificatyion with no JPA experience...luycky guy
    Thanks to you I can add another resource, actually I am reading the officiale book, yesterday I discovered
    this

    I have bought enthuware mock because it was great for the programnmer certification and i am wondering if epractize too is worth
    well let me know your progress
    thanks

    I am preparing from first edition.
    First edition should be sufficient I guess

    Just to be sure as i read this thread and some other threads , it seems the best resource to prepare is ProJPA 2 edition 1. My preparation goal is
    1. Finish the Pro JPA 2 book, by coding and modifying the examples.
    2. Take enthuware mock exams.
    Is it enough to prepare for the exam or should i also read JSR sepcification ? Moreover chapter 3 of Pro JPA talks about EJB stuff , is it relevant for the exam? or should i skip this chapter completely and move to chapter 4?
    Thanks

    Today I've passed the OCJPA exam with 86%. I've prepared from Pro JPA 2: read and (re-)created all the samples (e.g. from Chapter 10-Chapter 20 all the samples in the downloaded sources are empty, so you have to implement them.). Then I bought enthuware's mock exams, I have to say it's definitely worth for the money, the exam questions were quite similar.

    @hamada: the EJB questions are quite heavily asked on the exam (stateful and stateless beans, mdb not so often), so I suggest not to skip chapter 3.
