Hi,
The Q.3 says
Which are ways in which a client can get a reference to an existing entity object's local component interface?(Choose all that apply.)

A. Call ejbCreate()
B. Call getSessionContext()
C. Obtain the reference from the handle.
D. Receive the reference as a parameter in a method call.
E. Use a finder method defined in the local home interface.

Correct answers are D and E. That are fine.
But Ans. A is wrong. And the reason is said that "we said existing"

Even if its a NEW entity then also answer A is wrong. Because the client can NEVER call ejbCreate(). She can call create() not ejbCreate()...
Is my understanding correct?

Hi Sawan,

Option C is wrong because there are no HANDLE for the LOCAL interface. Handles are only for Remote interfaces.

oh. My mistake. I should have read the question carefully.


Yes your are right the client can call the create() method and the container will call the ejbCreate since its an callback method.

Thanks.
