A developer writes a stateful session bean FooBean with one remote business interface Foo. Foo
defines an integer / setter method pair implemented as:
10. private int value;
11. public void setValue (int i) {value = i; }
12. public int getValue () {return value; }
A session bean ClientBean has a business method doSomething and an ejb-ref with ejb-ref-name
fooRef that is mapped to FooBeans Foo interface.
11. @Resource private SessionContext SessionCtx;
12. public void doSomething () {
13. Foo foo1 = (Foo) sessionCtx.lookup(“fooRef”);
14. Foo foo2 = (Foo) sessionCtx.lookup(“fooRef”);
15. foo1.setvalue(1);
Which statement is true after the code at line 15 completes?
A.
Foo1.getValue () = = 0 and foo2.getValue() = = 0
B.
Foo1.getValue () = = 0 and foo2.getValue() = = 1
C.
Foo1.getValue () = = 1 and foo2.getValue() = = 0
D.
Foo1.getValue () = = 1 and foo2.getValue() = = 1
Explanation:
Foo1 and Foo2 references the same object.
C
C
C
It’s stateful session bean so only answer C is correct
For Stateful Session bean foo1.equals(foo2) always false.
People you all wrong its D
