28.OldBarBean is a stateless session bean written to the EJB 2.1 API with remote home interface.
OldBarHome and remote component interface OldBar. FooBean is a stateless session bean written to the
EJB 3.0 API.
OldBarBean and FooBean are the only EJBs packaged in the ejb-jar. The FooBean portion of the ejb-jar.
xml also declares an ejb-ref whose ejb-ref-name is ejb/oldBar. The ejb-ref is linked to OldBarBean. There
are no other ejb dependencies defined.
A business method foo in FooBean needs to access OldBarBean.
Which is portable code to achieve this goal?
A. .Remote
private OldBar oldBar;
B. public void fooQ
{
try
{
InitialContext ic = new InitialContextO;
Object obj = ic.lookup("ejb/oldBar")
;
OldBarHome OldBarHome
=
(OldBarHome) PortableRemoteObject.narrow(obj,
OldBarHome.class)
;
OldBar oldBar = oldBarHome.createO;
C. @EJB private OldBarHome OldBarHome;
public void fooQ
{
try
{
OldBar oldBar = oldBarHome.createQ;
D. public void fooQ
{
try
{
InitialContext ic = new InitialContextO;
OldBarHome OldBarHome
=
(OldBarHome) ic.lookup("ejb/oldBar")
;
OldBar oldBar = oldBarHome.createQ;
