Howdy y'all, what y'all doin'?!
Champions, I just took the 310-091 exam and I'm glad to say that I passed with 95%. My preparation included the books
EJB3 in Action,
Enterprise JavaBeans 3.0,
Mikalai Zaikin's Excelent SCBCD 5 Study Guide and the amazing discussions that always go on the
EJB Certification forum.
I feel that I could have done better if I was working with EJB3, but at the moment all I use is Spring, Hibernate and other smaller frameworks. Anyway, another certification won't certainly do any harm!

Cheers, Roberto Perillo
