I would like to take this opportunity to thank everyone at JavaRanch (especially at EJB and SCBCD forums) for giving great answers to my question.
Also thanks a lot to Kathy Sierra and Bert Bates for the excellent "Head First EJB" book.
In my preparation I used this book, JavaRanch forums (mostly EJB and SCBCD forums) and EJB 2.0 spec. At the end used ejbcertificate.com and Final Mock Exam at the end of the book to test my knowledge on ejb 2.0.
feeling good on the forum...seems am at right place. Congrats Alex for clearing exam with flying colors. As am preparing for JCP 1.4... looking forward for nice tips / links /anything which you feel will be helpful.
