1. JSR 220 EJB3 now is "public review" not "final release" 2. I guess that banq don't read spec or *really* use EJB3 now ! Banq, u have too many wrong thoughts in EJB3 . 3. Besides Jboss4 , Oracle is the JSR 220 RI vender, so that u can also download the oracle ejb3 server in his site, and u can test EJB3 in Sun opensource Application Server "GlassFish" 4. EJB3 != EJB2+xdoclet , EJB3 is so different from EJB2 ! 5. EJB2 is out-of-time NOW , especially in EntityBeans so, if u wanna use new architecture in O/R mapping, Please use Hibernate3 or Hibernate EJB3, u can understand EJB3 soon !
6. Annotation vs Descriptors ? which one is better ? They are co-operation, although Community hope annotation to replace descriptors. "zhuam" use my post from javaworld :( ( Never tell me ) http://www.jdon.com/jive/thread.jsp?forum=91&thread=22356
