Yesterday I passed this certification with 77%, I was aiming for 80% or higher but still VERY HAPPY with the pass and everything I have learned in prep for this exam, which has helped me develop web services at work as well.
The following materials were very helpful in my preparation
- Java Web Services: Up and Running (Martin Kalin) - VERY GOOD
- ocewsd6-guide and quizz - Mikalai Zaikin - VERY GOOD
- scdjws5-guide - Mikalai Zaikin - VERY GOOD
- javaeetutorial 6 (Web services section only)
