Oracle Java EE 6 Enterprise JavaBeans Developer Certified Expert 認定 1Z0-895 試験問題：

問題 #1

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. 2
C. 1

問題 #2

Assume you would like to receive notification from the container as a stateless session bean transitions to and from the ready state.
Which of the following life cycle back annotations would you use? (Choose one.)

A. @PostConstruct, @PostDestroy
B. @PostConstruct, @PostDestroy, @Remove
C. @PreConstruct, @PostDestroy
D. @PostConstruct, @PreDestroy, @Remove
E. @PostConstruct, @PreDestroy

問題 #3

Given two stateless session beans, ABean and BBean:

A client that is not executing within a transaction acquires an EJB reference to ABean and invokes the a() method on time. How many distinct transactions are started by the container after all
processing has completed?

A. 0
B. 2
C. 1
D. 3

問題 #4

A developer implements a stateless session bean as a timed object. The bean contains two local business methods with the transaction attribute REQUIRED.

A client begins a UserTransaction and calls the foo local business method. The foo method returns five seconds later. The client rolls back the transaction and then calls the bar local business method. Assuming there have been no other client invocations on the stateless session bean, what is the value of the size variable when control reaches Line 18?

A. 0
B. 1
C. -1

問題 #5

A developer wants to package an enterprise bean FooBean within a .war file:
@Stateless
public xlass FooBean {
public void foo () {}
}
Which package approach is correct?

A. / (Root)
I - WEB - INF /
I - acme
I - FooBean.class
B. / (Root)
I - WEB - INF /
I - Classes/
I - acme
I - FooBean.class
C. / (Root)
I - acme
I - FooBean.class
D. / (Root)
I - META - INF /
I - acme
I - FooBean.class
