NO.4 A stateful session bean contains a number of instance variables. The types of instance variables A and
B are serializable. Instance variable B is a complex type which is populated by many business calls, and
can, therefore, not be refilled by the client without starting all over. A helper instance variable C is defined
as having a Serializable type, and can hold all the information which is in variable B. for example, B is of
type XML-DOM tree and C of Type String.
Which two solutions, when combined, maintain the state of the session bean over a passivation and
activation by the container? (Choose two.)
A. The value of helper variable C is used to create the value of Instance variable B in the beans no-arg
constructor.
B. The value of helper variable C is used to create the value of instance variable B in a @postcreate
annotated method.
C. The value of helper variable C is used to create the value of instance variable B in a @postActivate
annotated method.
D. Instance variable A must be made null and instance variable B must be converted to a Serializable type
and assigned to another instance variable in a @preDestroy annotated method.
E. Instance variable A must be defined transient. Instance variable B must be converted to a Serializable
type, set to null, and assigned to the instance variable C in a @PrePassivate annotated method.
