Oracle 1z0-895 Exam Practice Questions (P. 5)

A developer writes a stateful session bean FooBean with two local business interfaces Foo and bar. The developer wants to write a business method called getBar for interface Foo that returns a Bar reference to the same session bean identity on which the client onvokes getBar.
Which code, when inserted on line 12 below implements the getBar method with the wanted behavior?
10. @Resource SessionContext sessionCtx;
11. public Bar getbar () {
12.
13. }

Given the following code in an EJB session bean:

Which code, inserted at Line 15, portably looks up the injected resource?

A developer is writing client code to access a session bean deployed to a server instance.
The client can access the session bean under which of these circumstances? (Choose three)

A developer writes three interceptor classes: AInt, BInt, and CInt. Each interceptor class defines an AroundInvoke method called interceptor. In the ejb-jar.xml descriptor, CInt is declared as the default interceptor.
FooBean is a stateless session bean with a local business interface Foo that declares a method Foo ():
10. @Stateless
11. @Interceptors(AInt.class)
12. public class FooBean Implements Foo {
13.
14. @Interceptors (BInt.class)
15. @ExcludeClassInterceptors
16. public void foo () {}
17. }
What is the interceptor order when the business method foo () is invoked?

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?
