Hi folks i m preparing SCBCD 2.1

I am having 2 doubts
1.Why CMR field can only initiated in ejbPostCreate() not in ejbCreate()...

2.on page 290 of HFEJB Question 8
Whats true about the client's view of an entity bean 's remote component interface ? (choose all that apply)

A. Mulitple clients can access the same entity object concurrently.
B. New Entity beans can be created using a method in this interface.
C. Entity beans may not survive a crash of the container
D. Business methods cannot return a reference to the entity object.

I think answers are A,D both are true..but answer give is A only.I am having doubt...D is true becuase B.M can not return a reference to entity object it should be EJBObject reference of Entity Bean...

Guys..please give help me out.
