i have purchased head first ejb am planning to prepare for SCBCD exam,
1}is this book sufficient to know all concepts in ejb an to clear the exam? if not what other books/notes i need to prepare.
2} how long will it take to prepare for this exam.
3}what are the syllabus for SCBCD.
I strongly recommend you reading FAQ before creating this kind of topics. And you could use also 'search' button, you will find about 1000 topics with this question. The SCBCD exam covers EJB 3.0, Head First is about EJB 2.1 - this is a big difference.
