isIdentical()

[Tejastejas Gokhale]

Why does this always return false for stateful session beans? It may be possible that I have two stubs at client side(same client) reffering to same EJBObject on server side.
Or even two references to same stub?

Stateful session beans have a one to one relationship between clients and their component interface implementors (or EJBObject). Given this condition, no two instances of EJBObject can be the same.

Hi,
For a stateful bean, the bean will maintain the conversational state of the client. Eventhough the bean comes from the same home, it will always return false.

Thanks and Regards,

Correct. but what i am saying is same client can have two stubs to same EJBObject.or
it can have two references to same stub itself. Then in that case isIdentical should return true.

Hello Tejas,

This is what the spec has to say....

The following example illustrates the use of the isIdentical method for a stateful session object.
FooHome fooHome = ...; // obtain home of a stateful session bean
Foo foo1 = fooHome.create(...);
Foo foo2 = fooHome.create(...);
if (foo1.isIdentical(foo1)) {// this test must return true
...
}
if (foo1.isIdentical(foo2)) {// this test must return false
...
}

Is the second stub (object) just a simple copy of the first? In that it will return TRUE.. no?

No and No. EJB does not work like a Servlet would (meaning that it doesn't recognize inbound requests from the same client implicitely). Each call to create() would create another stateful session bean instance.
