Hi,
In HF EJB Book on Page 368 & 369
Question 5 Which are legal declaration for a CMP bean's ejbCreate methods?
A. public void ejbCreateBigCustomer() throws javax.ejb.CreateException
B. public String ejbCreateAccount() throws javax.ejb.CreateException
C. static String ejbCreate() throws javax.ejb.CreateException
D. public int ejbCreate() throws javax.ejb.CreateException
E. public final String ejbCreate() throws javax.ejb.CreateException
According to Book Option B is the right answer but I think right answer is B and D both.
Same as in
Question 9 Which method(s) from EntityContext interface can be invoked from within the ejbCreate method?
A. getEJBHome()
B. getEJBObject()
C. getCallerPrinciple()
D. getUserTransaction()
E. setRollbackOnly()
According to book right answer is A,B,C,E.
and I think for this A,C and E are the right answer.
Please put some shed on it if i'm wrong.
Regards,

Hi there,
the answer to question 5 is indeed only option B.
The thing is that the ejbCreate should return the primary key class and a primitive is not valid for this.
You can explicitly see this in the signature of the getPrimaryKey method:
public Object getPrimaryKey() throws RemoteException which returns an Object.
I think you are right concerning question 9.

Question :5
See Spec p: 172
public PrimaryKeyClass ejbCreate<METHOD>(...);
- the return value is a class and not a primitive.

Question :9
see Spec p:179 (Table 4).
There is no getEJBObject() or getUserTransaction() method in the list of allowed operations. Moreover Kathy has mentioned in the thread ...
https://coderanch.com/t/158300/java-EJB-SCBCD/certification/ejbCreate
that getEJBObject() method can be called only in the stateless/stateful session beans and not in entity beans.
I also think that this is an error.

Oh, sure, you could do that. Or you could eat some pie. While reading this tiny ad:
