Hello, I want to study for the Sun Certified Business Component Developer Exam. I have bought Head First Enterprise Java Beans. This book covers the older version of the exam. If i want to go for the newer version, will I benefit from this book.And what are the Java J2EE version associated with two exam versions.
I once read in this forum that new EJB is based on the old 1.3 EJB. I am not sure. If so, I will study the 1.3 and probably take the 1.3 Certification exam. Is there very huge differences between the two.
