Question 11

What are the requirements for a primary key class that maps to multiple fields of an entity bean class?

a. The primary key class must be private and be an inner class of the entity bean class.

b. The primary key class must be public and abstract as the container will be responsible for providing an implementation of the primary key classes.

c. All fields of the primary key class must follow the JavaBeans conventions, that is, the fields must be private, and public accessor or mutator methods must be provided.

d. All fields of the primary key class must be declared public (and thus, break the encapsulation of the primary key class).

e. Only the container-managed field names of the entity bean declared in the deployment descriptor can be used as field names in the primary key class.
