Thanks to everybody in this forum. The HF is too good(thanks to Kathy and Bert) to understand the fundamentals but i guess this is not enough. I would like thank Sawan Parihar who really answered my most of the questions.
I prepared for 3 months and studied -- HF, -- Spec(studied using valentine's spec-objective mapping). I guess this is what helped me a lot. -- Mikalai's notes -- Did couple of mock tests
Exam was bit easy just couple of tough questions. I faced tough questions in EJB QL.
I faced 2-3 questions in EJBQL and all were drag and drop. They give one database table and ask us to write query for specified requirement. It is tough in the sense that there were too many blanks to fill.
select -- from -- where -- -- -- AND -- --
Writing a query is NOT a problem but writing with all blanks filled was bit problem
