breakout.
B. Use the getCallerPrincipal method on an injected SessionContext to determine the required
information.

NO.15 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

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.16 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.

NO.20 XYZ Software develops business components using both the EJB 2.1 and EJB 3.0 APIs. Some
customers are reluctant to completely migrate to the EJB 3.0 model, but are willing to have EJB 2.1
session beans invoke EJB 3.0 session beans.
How should XYZ Software enhance these components to meet this customer requirement?
A. Use @EJB to inject a reference to the EJB 3.0 business interface into the EJB 2.1 bean class.
B. Use <ejB. ref> in ejB. jar.xml for the EJB 2.1 bean to declare a reference to the EJB 3.0
business interface.
C. Add an EJB 3.0-style business interface to EJB 2.1 beans to achieve interoperability between EJB 2.1
and EJB 3.0 beans.
D. Use @RemoteHome and @LocalHome to adapt EJB 3.0 beans so that EJB 2.1 beans can look up the
adapted home interfaces using JNDI.
