I passed Scbcd with 92%. No prior EJB programming experience. Forty days of study (about 4-5 hours a day). Here's my prep: Read Mastering Ejb by Roman till Transactions and appendix c (ejb-jar.xml). Coded five EJB from the book,using IDEA and JBoss. Read Sun Tutorial. Read some Chapters from Enterprise EJB. Read Specs following Chettaz 's instructions. Read JavaRanch Scbcd Forum (all posts from the last ten days). As Study Guide i've used Mikalai ' Notes. Heavily used EjbPlus (Great !, real exam is a little easier).
