I guess I outperform myself on this one. I was really panic before the exam because of low score I got from ejbcertificate and the final mock exam in HFEJB.
Here are the materials I use to prepare for the exam, over one month period on and off.
1. HFEJB - I read it twice, the first time I was skimming through, the second time I read it really thorough and do all the execises, tested all the codes except many to many relationship. 2. Mikalai Zaikin's SCBCD Guide - it helps me go through the entire objectives from the perspective of spec. It actually covers something that the HFEJB doesn't cover. Thank you again, Mikalai. 3. Valentin Crettaz's cheat sheets - many thanks for the wonderful creative way of helping me remember the ejb-jar.xml and life cycle of ejb. 4. ejbcertificate mock exam - Don't be discouraged if you score low. There are questions in doubt or not clear in those mock exam. That won't happen in the real exam.
There are quite some code snippets you have to determine what is wrong or what it means. Watch out for those, because you hardly have this type of execise in the mock exams.
Now I can really relax and enjoy the coming holidays.
