Today is just not my lucky day, I encountered many ejb questions such as home, local interface, env-ref which I didn't expect to appear on exams. Currently I am looking for jobs and I feel the 310-081 certification isn't that much help on my job hunting, so I kind of wonder is it worth to try again, and advice is highly appreciate!
Thank you all for the careness, but right now I don't feel like taking it again until I get a job position. For those who prepare for the exam, the one I have yesterday is quite toup, spend me whole 2:30 hour to do it and review one time. Most question are on EL, EJB(as people mentioned aboved, it's just configuration question, nothing detail to programming), JSP, Design pattern, very few questions on servlet.
