This was a hard test.

I have developed JAX-WS services for my work. I also took the official week-long Oracle Web Services training for Java 6, which I thought would prepare me well (it did not).
I spent the last two weeks studying many hours a day.

I was not expecting that much of the test was conceptual. Lots of "best-practices" and security. WS-I compliant stuff. Few questions on DOM/SAX which I did not prepare for. Tricky questions about WSDL. Good amount of EJB-specific stuff.

My advice -- spend less time on coding/annotations and more on big picture stuff.

My other advice...expect to fail once. Remember the test questions you didn't know and research the answers. Then take it again. This one is hard.

For reference, I have passed the OCWCD exam with an 85%. This test is nothing like that.

Sorry to hear that. You can spend more time to prepare for the exam, like 3-4 months to read MZ's notes, Java Web Services Up and Running and Ivan's notes.
I worked full time and I spent a total of 14 months to prepare.

Do you buy EPractice Lab and Enthuware? I highly recommend you to use the mock exams. Try your best to understand the explanations given in the mock exams. They are helpful. Learning how to take the exam is important.

One more suggestion, this version 6 exam covers version 5 objectives as well. Be prepared there will be 2-3 questions from version 5 objectives.
For example, you have to briefly know what webservices.xml has and what it does. You also need to briefly know the difference between StAX and SAX ( eg iterative pattern vs observer pattern, more control vs less control, read and write vs read only and etc). You may want to read J2EE 5 tutorial for more detail about JAXB binding.
You may need to know web service cache/broker (in Ivan's notes) just in case the old questions come up.

No I did not buy anything. I thought the $$$ I spent on official Oracle Training would be good enough.

Your advice is definitely helpful and I hope that people preparing for this exam read it and take it seriously.

To be honest, I think taking it twice and failing the first time is a better option, along with using the software you recommend. While it costs more money up front, I think it is more economical in the long run. Time is money, as they say, and spending 3 months studying is a lot of time to spend for people/ with busy lives.

Sorry to hear you failed.

JFYI: from my previous experience with Sun (Oracle) trainings like SL-275 (which expected to prepare to Programmer exam), and SL-285 (which expected to prepare to Developer certification) - they covered like 30..40% of material from the test. Also, it's impossible to prepare to test in 1 week training (40 hrs). I would say at least 2...3 months preparation is a must.

Good luck,
MZ

Hi Jonathan,

It is a pity that you failed but don't give up! This is indeed a tough exam because it is not following a single specification like the WCD, JPA or EJB exam, and apart from that there is no book targeting the exam. The notes of Mikalai and Ivan are a must though.

My advice -- spend less time on coding/annotations and more on big picture stuff.


Be careful: coding does give you insight on how things work and makes sure that you don't fail the easy questions. There is no recipe for passing the conceptual questions although reading about web services design, SOA and Web services design patterns online helps. The message level security questions are a bit easier to prepare for, just check some of the threads in the Web Services (or Certification Results) forum for pointers.

Another advice: mock exams alone do not prepare you for the exam. You need to read and study stuff and not cram questions and answers.

Some pointers to the important documents that are covered by the exam can be found in this thread.

Good luck!

Regards,
Frits

sad to know about cert results but do not give up . take some weeks break then start a fresh ... follow java web service cert forum for any queries ... feel free to post any web service queries there... also read good books on web service (and practice lot of code)
