It is important to note that the attributes contained in the primary key class must be a subset of
the container-managed fields when using container-managed persistence. This enables the con-
tainer to match up the proper attributes from the bean class to those in the primary key class.
Bean Class
This EJB's bean class contains the business logic of the entity bean. It has similar rules to the
bean class for a session bean, just many more of them. It implements all of the business meth-
ods from the remote interface. It has methods that match each of the methods in the home
interface. There is also a group of callback methods that are used by the container to manage
the bean.
