@SUNCertified(name="SCBCD5", scored="91%")

Do you wonder why I have named this bolg entry as Java technology annotation (JSR 175). Really this is a cool feature that has been added in JavaSE5 changed the way of coding style for Enterprise Java Beans (EJB3). In my previous company we used EJB2.1 for developing an enterprise distributed application. I just wanted to updated my EJB coding skills, so I planned for writing SCBCD5 Sun Certification Exam. I have chosen following books and online material for preparation.

> EJB3 O'Reilly book.

This is a nice book which has two parts. First part explains about EJB3 and second part is JBoss workbook. I read only fist part and used Netbeans 6 with glassfish V2 to practice EJB3 sample codes. I have noticed a typo in this book at page number 172 in chapter 9. It says Query#getSingleResult() throws javax.persistence.EntityNotFoundException If no result returned. But this is not true, Query.getSingleResult() throws javax.persistence.NoResultException if there is no result. For the exam it is important to remember that the exceptions NoResultException and NonUniqueResultException thrown by this method does not cause the transaction to roll back.

>SCBCD 5.0 Study Guide prepared by Mikalai Zaikin - I want to thank Mikalai Zaikin for providing the preparation material. I have a short time to prepare so I have chosen this guide over EJB3 specifications. He prepared this notes from the EJB3 Specifications.

>Sun Learning services EJB3 online training. - This training is free for sun employees. It is exceptionally good.

>Enthuware mock exams - These mock exams are very good really helps you for the exam.

>Whizlabs mock exams - I tried only few exams because there are many typos and mistakes. I suggest them to get everything rectified.

>www.javapassion.com - This website also helps you a lot.
