hi fiza,
i recommend Monson Haefel becuase it is good
(initially i could not grasp much but i tried to uderstand the overall idea and read again so things got pretty clear)
Masting EJB is also good thought i did go thourgh much i guess after reading Monson Haelfel i had t just skip many things.
but if you are starter on EJB then Mastring might help you since it gives you good starting ...
AS you have been advise my other guys ...
do try to understand .. i have good understanding of EJB but still i lost marks (i felt so bad

.. may be it was my first
test)
feel free to ask any thing ... people over here are g8 help
anyhow good luck.
Atif
