Recently I passed 1Z0-895(Java EE 6 Enterprise JavaBeans Developer Certified Expert Exam)with 83%. I would like to thank all fellow ranchers for their posts and success stories. Those posts are very informative and motivational as well .
Here how I did it.
1. Read the EJB 3.1 Specification document.
2. Read the book "OReilly Enterprise JavaBeans 3.1".
3. Read the study notes by Frits Walraven and Ivan Krizsan. Thanks to both, those are really helpful.
4. Practice code. This is what which will give you confidence and better understanding of concepts.
5. And at end used Enthuware mock test. I like the explanations provided for each question in this mock test.
It took me approximately 4 months for preparation(2 hrs average). I found real exam a bit difficult(personal opinion). For me questions with multiple answers were headache .
