thanks for your info about monson�s 4th edition, frankie, but sorry, my question 1 has an error: I have roman�s book ,
,not monson�s book, and i have the doubt about to buy monson�s book 2nd edition, because i think this edition covers EJB 1.1, and it shows the differences between 1.1 spec and 1.0 spec.
i�m working developing and designing applications for the version 1.3 of J2EE, including ejb 2.0, so i know the main concepts about ejb, like types of beans, callback methods, transaction support, etc..., and i�m only looking for a book to learn the specific features of ejb 1.1, because this is the version included in the certification exam.
