Hi All,

I encounter the following question and I am not sure what is the answer. The question is shown as below.

Which of the following is used programmatically but NOT declaratively in EJB?
A. Transaction Management
B. Naming service
C. Persistence
D. Resource Management
E. Security

So can any expert know the answer and give a brief explanation on this?

Thank you so much

Regards,
Benny

A. Transaction Management - can be declared in DD (Transaction management type for bean etc.)

B. Naming service =====>> This looks to be a possible answer. Since Naming Service is not overridden in any way in the DD but it is used programmatically for find references to objects through JNDI.

C. Persistence - can be defined in persistence.xml (definition of persistence unit etc.)

D. Resource Management (ejb-res-ref, ejb-ref and other tags.. in DD)

E. Security (again security management can be done in DD - security-roles etc.)
