A developer writes a stateless session bean FooBean and uses its deployment descriptor to declare a local ejb dependency on a stateful session bean in the same ejb-jar.

Which environment annotation, when declared within the FooBean bean class, is equivalent to the ejb-local-ref shown above?

• A.@EJB(beanName="BarBean") Private acme.Bar barRef;
• B.@EJB(name="barRef", beanName="BarBean") Private acme.Bar bar;
• C.@EJB(name="ejab/barRef", beanName="BarBean") Private acme.Bar bar;
• D.@EJB(name="bar", beanName="BarBean") Private acme.Bar barRef;

Assume an EJB application is comprised of the following EJB fragment:

You have been asked to convert the type of InventoryReportBean into a singleton session bean. How would you achieve this task?
Exhibit C:

Exhibit D:

• A.Keep InventoryReportBean as it is, modifying the internal structure to function as a singleton
• B.Change the @Stateless annotation of InventoryReportBean to @Singleton
• C.Create an ejb-jar.xml file, and override the annotation configuration information as in exhibit D above.
• D.Create an ejb-jar.xml file, and override the annotation configuration information as in exhibit C above.

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?

• A.Option A
• B.Option D
• C.Option C
• D.Option B

Which is a valid use of the EJB 3.x TimerHandle object?

• A.To obtain a seralizable timer handle that may be persisted
• B.To be implemented by EJB classes that are to be registered with the timer service
• C.To adapt EJB 3.x timers to EJB 2.1 and earlier timers
• D.To retrieve all active timers associated with this bean

Given an JMS message-driven bean, which statement is true about its exception handling?
