Today I passed OCEJWSD (1z0-897 Web Services Developer Certified Expert Exam) with a score of 100%. I have a year of work experience in SOAP, which gave me enough basics to start my exam preparation.
Here are some resources that I used for this exam,
Java Web Service Up and Running, 1st Edition by Martin Kalin – As I already had the 1st edition of this book, I used this for my basic web service understanding (though the 2nd edition is available). Also, I have tried the coding examples stated in this book as hands on to clear my concept.
OCEJWSD 6 Notes and Quiz by Mikalai Zaikin – These materials gave me the first exam objective based understanding. Also I referred to the version 5 notes for some of the objectives (skipped UDDI and JAXR). I found it really helpful.
Enthuware mock exams by Frits Walraven – Enthuware mock exams really helped me a lot. The questions were pretty similar to the questions of the real exams. The explanations given for each and every question were on point to build my understanding. The Enthuware discussion forum was also very helpful for clearing any doubt.
Also for further understanding I referred to the following resources, JAX-RS spec, JAX-WS spec, Jersey documentation and Java EE spec V7.
Last but not least, thanks to Coderanch and Enthuware forums, especially to Frits Walraven for sharing his knowledge.
This exam is indeed a tough one due to the various resources to refer. For me, this exam took approximately four months of preparation.
