Session
and Entity EJBs consist of 4 and 5 parts
respetively:
1. A remote interface
(a client interacts with it),
2. A
home interface (used for creating objects
and for declaring business methods),
3. A bean object (an
object, which actually performs business
logic and EJB-specific operations).
4. A deployment descriptor
(an XML file containing all information
required for maintaining the EJB) or a
set of deployment descriptors (if you
are using some container-specific features).
5.A Primary Key class
- is only Entity bean specific.
