Yesterday I've successfully passed OCEEJBD6 exam with 81%.
There are only 3 materials that I've used in may preparation for the exam:
1. Enterprise JavaBeans 3.1, 6th Edition - Read it twice.
2. Frits Walraven OCEEJBD6 notes - Read it 3x actually, thank you Frits!
3. And the last was Enthuware Mock Exam. - As always, the quality of questions and explanations inside the mock exam gave me a lot of confidence and deep understanding of the EJB 3.1 concepts. Thank you Enthuware.
I've spent almost a month for the preparation.
