Is the JavaBeans 3.0 something completely different than JavaBeans 2.0? If I have a book for JavaBeans 2.0 can I use it for beginning or I shouldn't even start with it?

Hi Jakub,

They are very different. EJB3 is a lot simpler and makes use of annotations, so there's quite a big jump.

We say Enterprise JavaBeans, not JavaBeans That's different. If you want to study SCBCD5(EJB3.0), you really need a book about EJB3.

Enterprise JavaBeans (EJB) is not JavaBeans. I believe you mean EJB.

EJB 3's goal is to simplify Java EE development. It has many features that make it simpler and better than EJB 2, such as Annotations support, dependency injection (DI), interceptor, and use JPA for persistence layer instead of Entity Beans.
