Phewwww .... finally it is over. Many thanks to K & B for thier wonderful book. The exam was not easy and i faced 'system error' in one DnD question. Thanks to the ranchers, the discussion on this site helped me prepare better for SCBCD exam. I spent 2 weeks reading EJB specification and K & B HF-EJB. I used softSCBCD to get the feel of real exam questions. I found the simulator very helpful in my preparation. As someone said earlier, the tutorial in the simulator really rocks.
