You are using the wrong book. This book is for the old SCBCD 1.3 (EJB2.x), which is not available anymore.
And what is the Diff Between CX-310-091 and CX-310-092.
CX-310-092 is an upgrade, for anybody having already passed an old SCBCD. If you are not SCBCD certified, you need to pass the full exam (CX-310-091). Further details at Sun.
