Explanation:
The EJB tier hosts the business logic of a J2EE application and provides system-level services to the
business componentsproblems include state maintenance, transaction management, and
availability to local and remote clients.
The EJB 3.1 specification does not address "high-end" features like clustering (not B), load-balancing
(A) and fail-over (not E).
F: The target platform for EJB is Java EE.
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 developer examines a list of potential enterprise applications and selects the most
appropriate technologies to use for each application.
For which two applications is EJB an appropriate solution? (Choose two.)
A. To render a GUI for mobile clients.
B. As a container for web-tier components including JSP .
C. As a Web service endpoint accessed by non-Java clients.
D. To receive and respond to HTTP Post requests directly from a web browser.
E. As an online shopping cart which can persist across multiple sessions with a single client.
Answer: C,E

NO.6 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.

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 ending their session. The number of concurrent sessions will be greater than the defined
bean cache size.
The developer must consider that the state of the session bean can be influenced by either
passivation or timeout.
Which three actions should the developer take to make the bean behave correctly in passivation
and timeout situations? (Choose three.)
A. Release references to resources in a @Remove annotated method.
B. Re-establishreferences to resources in an @Init annotated method.
C. Release references to resources in a @PreDestroy annotated method.
D. Release references to resources in a@PrePassivate annotated method.
E. Re-establish references to resources in a @PostActivate annotated method.

Explanation:
Foo1 and Foo2 references the same object.
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

11. Which two statements are correct about stateless session beans? (Choose two.)
A. The bean class may declare instance variables.
B. The lifetime of the bean instance is controlled by the client.
C. The container may use the same bean instance to handle multiple business method invocations
at the same time.
D. The container may use the same bean instance to handle business method invocations requested
by different clients, but not concurrently.
Answer: A,C
Oracle 1Z0-895 dumps 1Z0-895최신덤프 1Z0-895 1Z0-895
Explanation:
* A: Stateless session beans are EJB's version of the traditional transaction processing applications,
which are executed using a procedure call. The procedure executes from beginning to end and then
returns the result. Once the procedure is done, nothing about the data that was manipulated or the
details of the request are remembered. There is no state.
These restrictions don't mean that a stateless session bean can't have instance variables and
therefore some kind of internal state. There's nothing that prevents you from keeping a variable
that tracks the number of times a bean has been called or that tracks data for debugging. An
instance variable can even hold a reference to a live resource like a URL connection for writing
debugging data, verifying credit cards, or anything else that might be useful.
C:A stateless session bean is relatively easy to develop and also very efficient. Stateless session
beans require few server resources because they are neither persistent nor dedicated to one client.
Because they aren't dedicated to one client, many EJB objects can use just a few instances of a
stateless bean. A stateless session bean does not maintain conversational state relative to the EJB
object it is servicing, so it can be swapped freely between EJB objects. As soon as a stateless
instance services a method invocation, it can be swapped to another EJB object immediately.
Because there is no conversational state, a stateless session bean doesn't require passivation or
activation, further reducing the overhead of swapping. In short, they are lightweight and fast!
* The Lifecycle of a Stateless Session Bean Because a stateless session bean is never passivated, its
lifecycle has only two stages: nonexistent and ready for the invocation of business methods. The EJB
container typically creates and maintains a pool of stateless session beans, beginning the stateless
session bean's lifecycle. The container performs any dependency injection and then invokes the
method annotated @PostConstruct, if it exists. The bean is now ready to have its business methods
invoked by a client.
At the end of the lifecycle, the EJB container calls the method annotated @PreDestroy, if it exists
(not B). The bean's instance is then ready for garbage collection.
12. A developer wants to release resources within a stateless session bean class. The cleanup
method should be executed by the container before an instance of the class is removed. The
deployment descriptor is NOT used.
Which three statements are correct? (Choose three.)
A. The cleanup method may declare checked exceptions.
B. The cleanup method must have no arguments and return void.
C. The cleanup method is executed in an unspecified transaction and security context.
D. The developer should mark the cleanup method with the @PreDestroy annotation.
E. The developer should mark the cleanup method with the @PostDestroy annotation.
F. The cleanup method is executed in the transaction and security context of the last business method Invocation.
Answer: B,C,D

NO.10 Foo foo1 = (Foo) sessionCtx.lookup("fooRef");
NO.11 Which two statements are true? (Choose two.)
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.
Answer: B,D

The Lifecycle of a Stateless Session Bean The EJB container typically creates and maintains a pool of
stateless session beans, beginning the stateless session bean's lifecycle. The container performs any
dependency injection and then invokes the method annotated @PostConstruct, if it exists. The bean
is now ready to have its business methods invoked by a client.

The bean's instance is then ready for garbage collection.
Lifecycle of a Stateless Session Bean:
Note: An enterprise bean goes through various stages during its lifetime, or lifecycle. Each type of
enterprise bean (stateful session, stateless session, singleton session, or message-driven) has a
different lifecycle.
