This is a very excellent book for SCBCD. Anyone interested to pass the exam should not miss this book. This book is very clear and makes learning EJB very easy. This book is very outstanding and I wish the authors write more books so that we can enjoy them. I passed the SCBCD with a score of 92% and I am very thankful to the authors. I cannot imagine how difficult it would have been to learn EJB without this book.
