EJB 3.0

  Asked By: Nisha    Date: Mar 22    Category: Java    Views: 725
  

J2EE is going to be more easy to use than before by EJB 3.0,
this was the biggest news of TheServerSide Symposium,
the new spec will get a lot of its ideas from some popular open source projects
such as Hibernate and Spring,
the most important changes in EJB 3.0 are:
- POJO based(plain old java objects - nothing to extend)
- Dependency Injection
- Testability outside the container
- Annotations
- CMP becomes like Hibernate

See: www.theserverside.com/.../thread.tss

So we can think again about J2EE with EJB.

definitely, you can, as you could do it in ejb2.0/2.1 , but ejb  3.0 in its new features has added explicit joins.
