Once again I want to Thanks Katty & Berts ( specially Bert. You are really motivating me ) Please give attentions to every detail in the HF EJB book. Please note that you should remember the basics very well.
I also used notes from Mikalai Zaikin and skim through EJB spec. actually I practised with J2EE 1.4 (application server 8.1) and NetBeans I felt 1.4 is only little different from 1.3.
My approach is very simple I read the Head First book and understood the theory. then with netbeans and sun application server 8.1 got some practical experience. I used netbean tutorials on EJB also. then skim through Mikalai Zaikin notes and spec then mock exam from http://www.j2eecertificate.com/ thats all. rgds janaka
