NO.4 A developer writes a stateful session bean FooBean with one remote business interface Foo. Foo
defines an integer / setter method pair implemented as:
NO.5 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.

A. Typically, remotely accessible objects should be coarse-grained.
B. If a client accesses an enterprise bean locally such access must be mediated by the EJB container.
C. A given enterprise bean's transaction information is immutable because it is deployed across various
containers.
D. If a container provides services NOT required by the EJB specification, then that container is NOT
considered to be an EJB container.
E. An enterprise bean's transaction Information can be accessed by external tools only if the information
is contained in an XML deployment descriptor.

7.A developer creates a stateful session bean that is used by many concurrent clients. The clients are
written by other development team; and it is assumed that these clients might not remove the bean when

timeout.

timeout situations? (Choose three.)

10.A developer writes a stateless session bean FooBean with one remote business interface FooRemote
containing one business method foo. Method foo takes a single parameter of application-defined type
MyData.
11. public class MyData implements java.io.Serialization {
12. int a;
13. }
Methods foo is implemented with the FooBean class as:
11. public void foo (MyData data) {
12. data.a = 2;
13. }
Another session bean within the same application has a reference to FooRemote in variable fooRef and
calls method foo with the following code:
11. MyData data = new MyData();
12. data.a = 1;
13. Fooref.foo(data);
14. System.out.printIn(data.a);
What is the value of data.a when control reaches Line 14 of the client?
A. 0
B. 1
C. 2
