Hey Rami,
I figure you are quite new to programming with the EJB model going by your statement "really its hard to study. I am using 3 books and its confusing and hard to be done". What you were looking for i guess is some material to jump-start you, possibly quickly 'get your feet wet' with real and complete working code that you can easily copy, compile and execute without going round circles reading heavy paragraphs that 'seem to complicate' even the most trivial of principles. Richard M. Reese has a good book for new-comers like i was myself. It's called "EJB 3.1 Cookbook" published by packt. It quickly gets you into coding using only minimal working code. It also ties you straight to Glassfish+Netbeans (in my view a very bold move to keep things simple and straight forward). Some books opt to be neutral on this hoping to embrace developers from all brands of app servers. The price they pay is that total beginners find it next-to-impossible to understand stuff they cannot easily code and execute. There is nothing that boosts confidence and enforces knowledge than minimal, simple, yet complete working code in the context on an appserver, early in the book's chapters (especially chapter 1!) for a total new-comer to the EJB model. Thereafter progress to the Rubinger book, Frits/Ivan notes, EJB spec & Enthuware mocks become steadily easy. By the way this is purely my opinion Rami.
I wrote the exam this morning and right now just waiting for certview to post my results. They say it takes 30 min but i have been waiting for quite a while now. I shall post results in the right forum as soon as they become available.
Good-luck.
