I just passed the Java EE 6 Enterprise JavaBeans Developer Certified Expert exam with score 90%.
it took from me just 19 days with about 2 hours average daily
I had prior basic experience with the Enterprise JavaBeans technology concepts
I used the following material:
a) EJB 3 In Action 2nd Edition (which cover EJB 3.2 and JPA , i just used the EJB part not the full book)
b)Ivan A Krizsan OCPJBCD-6-Study-Notes
c)Frits Walraven OCPEJBD 6 EJB 3.1 notes (is a must)
d)Enthuware practice exams (is a must)
My study plan was as follows:
i read topic (exam objective) from "EJB in Action" to get the idea
then i study the same topic from "Ivan A Krizsan OCPJBCD-6-Study-Notes"
after that i review from "Frits Walraven OCPEJBD 6 EJB 3.1 notes"
at last i try and study all questions of that topic from EnthuWare
i would like to Thank and appreciate "Ivan A Krizsan" and "Frits Walraven" for their wonderful Notes
and of-course the magical product ENTHUWARE its just magic
enthuware not just questions and answers ,it explanation of EJB in different way
you can choose different material for studying EJB but Enthuware is MUST
