문제 #1

An ejb-jar also contains three interceptor classes: AInt, BInt, CInt. Each interceptor class defines an AroundInvoke method called intercept.
The ejb-jar also contains a stateless session bean FooBean with a local business interface Foo that declares a method foo ():
10.
@Stateless
11.
@Intercaptors ({CInt.class, BInt.class})
12.
public class FooBean implements Foo {
13.
14.
public void foo () {}
15.
16.
}
The ejb-jar contains a META-INF/ejb-jar.xml file with an <interceptor-binding> section:
<interceptor-binding>
<ejb-name>FooBean</ejb-name>
<interceptor-order>
<interceptor.class>com.acme.AInt</interceptor-class>
</interceptor-order>
</interceptor.binding>
What is the interceptor order when the business methodfoo() is invoked?

A. AInt
B. CInt, BInt, AInt
C. AInt, CInt, BInt
D. AInt, BInt, CInt

문제 #2

Which API must an EJB 3.1 container make available to enterprise beans at runtime?

A. The JXTA 1.1 API
B. The MIDP 2.0 API
C. The Java SE 6 JNDI API
D. The Java SE 5 JDBC API

문제 #3

Suppose developer wants to create an EJB component that performs data validation every hour. Given the following Stateless session bean:

What is the minimum modification you would need to make to the bean to support notification from the TimerService once the timer expires?

A. Modify the verify external orders method to look like this: @TimeOut private void verifyExternalOrders () { / / do something }
B. Modify the verify external orders method to look like this: @ejbTimeOut private void verifyExternalOrders () { / / do something }
C. Modify the verify external orders method to look like this:
@EjbTimeOut
private void verifyExternalOrders () {
/ / do something
}
D. Modify the verify external orders method to look like this:
@TimedOut
private void verifyExternalOrders () {
/ / do something
}

문제 #4

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. 2
B. 3
C. 1
D. 0

문제 #5

Suppose a developer wants to create an automatic persistent timer that performs data validation every hour. Given the following stateless session bean:
@Stateless
Public class OrderVerificationBean {
Private void verificationExternalOrders () {
/ / do something
}
}
What is the minimum modification you would need to make to the bean to create the automatic persistent timer?

A. Modify the verifyExternalOrders method to look like this:
@Schedule (persistent = true)
private void verifyExceptionalOrders () {
/ / do something
}
B. Modify the verifyExternalOrders methos to look like this: @Schedule private void verifyExternalOrders () { / do something }
C. Modify the verifyExternalOrders method to look like this:
@Schedule (hour = "*", persistent = true)
private void verifyExceptionalOrders () {
/ / do something
}
D. Modify the verifyExternalOrders method to look like this:
@Schedule (hour = "*")
private void verifyExternalOrders () {
/ / do something
}
