Question on cheat sheets and Zaikin material

[Loga Nathan]

Hi,
I'm using the HeadFirst EJB book and SoftSCBCD. I would like to know:
1. Is there anything in the spec that is not covered in the book?
2. In Valentin Crettaz's cheat sheets, if it says for eg: 17.2 or 17.3.1, how deep should we go, like does it include 17.2.1,17.2.2 etc., Please suggest. This is not to cheat the cheatsheets but to be sure to sit for the exam
3. Can we safely read Mikalai Zaikin's material instead of the spec for that is also taken from the spec?
Appreciate your help.

In my mapping, when I say 17.2 I really mean "17.2 and all sub-sections unless otherwise mentionned"
Happy learning

howdy, Loga !
yes, you CAN *safely* read my notes, I have tested them *myself* while read twice. They guarantee you deeeeeeep sleeeep if you read in the night...
Note, if you try to read HF EJB, you will get opposite effect - you will be
laughing boisterously while read THIS book.
and, yeah, nobody (except Kathy, of course) can compete in EJB knowledge with specification authors. So, I just took excerpts from spec and put them on web-site.
cheers !
