A quick question for an EJB newbie. How different are the specs for EJB 2.0 from EJB 1.1
- I understand the addition of Message beans
but what has changed for the existing
functionality (Session & Entity Beans)
Thanks!

In terms of Entity Beans and Session Beans,
1) Local Interfaces have been introduced.
2)Unchecked Methods
3)runAs identity
4)ejbCreate<SUFFIX> methods.
In terms of CMP beans:
1) Now the bean implementation class has to be declared as abstract.
2)Relationships between beans
3)EJB QL(query language)
4)Home methods (BMP also).
5)ejbSelect()
