NO.1 A developer writes two session beans which cooperate. The first session bean, ShoppingCart, collects
orders and is implemented as a stateful session bean. The second session bean, CalculateDiscount, is
implemented as a stateless session bean and runs on a different server. ShoppingCart contains the
method getTotalPrice, which calculates the total price of the order in the ShoppingCart, including
discounts. Discounts are calculated by CalculateDiscount using the information on the ShoppingCart
bean, combined with data from a database. Which scenario can accomplish this?
A. The CalculateDiscount offers a method calculate which is invoked by the ShoppingCart bean passing
the this reference.
B. The CalculateDiscount offers a method calculate which is invoked by the ShoppingCart bean.
CalculateDiscount accesses the ShoppingCart instance by JNDI lookup.
C. The CalculateDiscount offers a method calculate which is invoked by the ShoppingCart bean passing
its reference obtained from the SessionContext.getBusinessObject method.
D. The CalculateDiscount offers a method calculate which is invoked by the ShoppingCart bean.
CalculateDiscount accesses the state of ShoppingCart by dependency injection.

NO.13 A stateful session bean contains a number of instance variables. The types of instance variables A and
B are NOT 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.
