Hi I decided to take my SCBCD cert in last december, that is how I reached here. I was working on EJB2.1 but not any Entity bean exp., I bought the book from Head first, unfortunaelty I could not follow their style(I belong to old school), I stopped reading that book and I ordered the book SCBCD Exam Study Kit: Java Business Component Developer Certification for EJB by Paul Sangarah. It is good. I bought the Whizlabs practise test and Ethuware( I think whizlab is enough, since I dont want to take a chance I have given my SCJP 7 years ago). Really worked hard and struggled for 1.5 months with a full time job and a family. After two weeks of study I start scoring 60 to 70% in practical exam , then I found my ejb-jar.xml tag knowledge and other small things are poor, then I concenrated on that part, after a week my score went above 90%. Then I felt confident I decide to give the exam. That is my story.
