After coming close to taking the exam twice but stopped by life's problems, this time I faced even greater challenges. I can't possibly express how relieved I'm feeling now, after almost 6 weeks of grueling preparation with sometimes less than 4 hours of sleep per day.
That being said, there were questions from all exam topics. A few unknown questions about WS-I and WS-Security, some thought provoking questions about best practices and design. Couple questions about JAXP. Rest the usual stuff...no questions on UDDI or dynamic discovery, if you're wondering.

I prepared with the following material/books:

  • Java Web Services Up and Running, 2nd ed. I read it cover to cover.
  • RESTful Java with JAX-RS 2.0. I read it cover to cover. (JAX-RS 2.0 is not in the exam but if you're learning it, better learn the latest and greatest too).
  • Mikalai Zaikin's OCEWSD 6 Quiz (Unlike the study guide, it's not free).
  • Ivan Kriznan SCDJWS 5 Study Notes. It's a little outdated but still plenty useful. I skipped some sections and code either because I already knew those or didn't feel it was relevant to the latest exam.
  • Enthuware OCEWSD 6 exam simulator.
  • I referred to the specs whenever in need but did not study any as such.

  • Most importantly, I wrote lots and lots of code. For the "Java Web Services Up and Running" book, I converted almost all the code in the book to Maven projects, the book uses Ant.

    Hi, Sarkar. Congrats. Thanks for your help.
    You must have some work experience related to JAX-WS or JAX-RS and that is why you only need 6 weeks to prepare. Since I am a newbie to web service, I need to spend more time on that. I have already spent 8 months reading Java Web Services Up and Running and some other books.
    I read Java Web Services Up and Running book 1st edition.

    I have a few questions about this book:
    1. Is JAX-RS WADLing on the exam?
    2. Is Restlet Framework on the exam?
    3. Is persistence of configuration file / database support through an @Entity on the exam?
    4. Which chapters of the first edition I should skip for the exam?

    Congrats for passing exam
    have couple of questions. I have never worked on EJB. I only have functional knowledge of EJB2. to what extent should I prepare exam topics covering EJB3 ?
    From which book you have read EJB 3 related topics ?

    Thanks
    Abhay Agarwal

    I do have working experience with Web Services but IMHO, prof. experience is not a crucial factor in this exam. The kinda questions they ask are from the guts of the spec and hardly seen in every day scenario. I also came close to taking the exam twice before so I had some faint memories of previous preparations. Lastly, I stressed on coding a LOT instead of just reading the books/study material which took me longer. Without that, I'd have taken the exam in 4 weeks or less.

    1. No.
    2. No.
    3. No.
    4. I can't tell; as I answered to you before, I didn't read the 1st ed of the book you mentioned, I read the 2nd ed.

    They sure did but I wish you weren't so protective about the quiz. Lot of times, I wanted to copy some code and run it but because of the copy protection, I ended up typing 'em all. I understand copyright constraints but having purchased the material, I'm sure people will appreciate a little ease of working.

    The only EJB specific topics you need to know in detail are security and exposing an existing EJB as a Web Service. In addition, you need an understanding of thread safety with EJBs, ability to manage transactions and other container provided services. You do not need to know how to configure those, just what the EJB is capable of.
    I didn't read any EJB 3 specific topics for this exam. I've the SCBCD certification, so I already knew about EJB 3s. However, as I said above, you shouldn't need to go into EJB 3 details. That said, if you insist on reading an EJB 3 book, I highly recommend Enterprise Java Beans 3.1. HTH.

    Or you can read the Java EE6 tutorial (Part IV Enterprise Beans and Part VII Security)

    May be it's just me but the thing I don't like about the Java EE tutorial is that it's teaching is very coupled with NetBeans. Also they don't give the code for download anymore.

    Yeah, I never look at their coding examples. I only use it for the theory that contains sometimes a nice explanation to a dry part in the specifications.
