Assume you have been tasked with building an ejb-jar containing an EJB application. The EJB application contains local, remote, and web service end-point EJBs that provide reusable sevices within an enterprise. When the application is deployed, client will access the remote session beans using the global JNDI name java:ServiceLayer/<bean_name>. All of the EJBs are located in the com.acme.sevicelayer package and are deployed as class files. The application uses a mixture of deployment descriptor and annotation configuration.
Which JAR representation best represents deployed structure for the previous requirements?

Which API must an EJB 3.1 container make available to enterprise beans at runtime?
정답: B
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 developer writes a stateless session bean HelloBean that exposes a local business interface Hello: The developer wants to test HelloBean using the EJB 3.1 Embeddable API. Given a main method with the following code:
100. EJBContainer container = EJBContainer.createEJBContainer();
Assuming HelloBean is packaged in hello.jar and included in the classpath, which code correctly acquires a reference to HelloBean?
100. EJBContainer container = EJBContainer.createEJBContainer();
Assuming HelloBean is packaged in hello.jar and included in the classpath, which code correctly acquires a reference to HelloBean?
정답: A
