Thanks to all the guys who have helped along and so too for Bert & Kathy for writing a nice book.
Exam appeared preety much straight forward.
TO ensure 100% success, it is important that you follow specs for EJB QL, CMP and RunTime Env.
Regd the exam, it is impt to know the 6 EJB roles very well. EJB QL was bit tricky but not tough. Ensure that you know to frame the queries using the 20 key words. Drag and drop are bit problematic as answers get reset on review. See that you answer them perfect on first shot.
A small correction for resource ref child element res-auth values. In HFEJB, Bean and Container are given to be the values but the correct values are Application (is the value for Bean managed Auth)and Container.
