Hi all,

Today I passed the Java EE 6 Web Services Developer(1Z0-897) exam.
For me this forum helped a lot in the preparation for the exam.
Therefore, I decided to open a thread to share my knowlegde among other exam candidates.

First of all I want to mention that I passed the exam with 85% so my preparation was not perfect.

Because pf prior work experience I already had a lot of knowlegde about webservices.
In addition to this I studied about 5 days (4 รก 6 hours) for this exam.

I mainly used the Enthuware question bank developed by Frits Walraven.
This really helped me to get the details straight, because I already knew the global concepts.

My advice on how to prepare:

First read a lot about Web Services.(e.g. Web Services Up and Running).
Second develop a JAX-RS REST service with EJB as root source. + client(jersey).
Third develop a very extensive JAX-WS SOAP web service with all the tools possible(i.e. adressing, handlers etc.) + clients(proxy + dispatch).
Fourth practice the Enthuware question bank for 4-5 days straight to get all the details you need to know.

Finally, I want to use this opportunity to thank Frits for his effort on creating the Enthuware question bank. These questions were very useful for me.

Bedankt Frits !

Kind Regards,

Hi Roel,

Thanks for your quick and most valued response. I already thought that I had read somewhere that release date of this particular beta exam was in april, but unfortunately I couldn't find the place it was stated.

Keep up the good work,

I have just passed the Java Certified Professional, Java SE 7 Programmer exam(1Z0-804). Next, I want to take the 1Z0-810 exam to extent my knowledge to the Java 8 environment. My question is: Does anyone know how long this exam stays in the beta phase?

Taking the exam in this phase is much cheaper($50 vs 245). Therefore, I want to know how much time I have to study for the exam;)

Thanks in advance,

Dear Java ranchers,

Today, I passed the OCA Java SE 7 exam(90%).
First of all. I want to thank all forum members for your clear explanation on oca 7 related questions.
I myself learned a lot while reading this forum. Therefore, I will share my experience with you.

These are the study materials I used:

- OCA Java SE 7 Programmer I Certification Guide (Mala Gupta).
- OCA Java SE 7 Programmer I Study Guide(Edward Finegan, Robert Liguori).
- Enthuware mock exams.

I learned the most from the enthuware mock exam questions. These questions are far more difficult than the mock exams of the two books I used.

My scores on the seven mock exams:

Test 1: 73%.
Test 2: 71%.
Test 3: 78%.
Test 4: 82%.
Test 5: 77%.
Test 6: 87%.
Last Day Test: 84%.

Advice: I think if you fully understand the Enthuware mock exam questions, you have a very high chance(>90%) to pass the OCA Java SE 7 exam.
