I used:
Enterprise Java Beans 3.0 (OReilly - Burke, Monson-Haefel)Beginning EJB 3 Application Development (Apress - Kodali, Wetherbee)EJB 3.0 SpecsEPractice exams from Sun (GB-WGS-PREX-J091C) I haven't got much experience in EJB 3.0, so found it hard. I even failed my two practice exams (50% and 49% - second one was only 2 days before the real exam) But I found the practive exams invaluable, though a bit expensive at �40 for two.
I am glad it is all over, took about 2 months of reading start to finish, time to party now:
