Hi, all
I think it's ambigous because in "7.10.3 ejbCreate<METHOD> methods", EJB spec 2.0, it says:
In my opinion, the CreateException is optional. However, according to An SCBCD certification primer, the second question:
It assert that the CreateException is mandatory for create<METHOD> in session bean's home interface...
I think it's ambigous because in "7.10.3 ejbCreate<METHOD> methods", EJB spec 2.0, it says:
The throws clause may define arbitrary application exceptions, possibly including the
javax.ejb.CreateException.
In my opinion, the CreateException is optional. However, according to An SCBCD certification primer, the second question:
Consider the following session bean home interface located through the Java Naming and Directory Interface (JNDI).
Context initialContext = new InitialContext();
ProcessPaymentHome ppHome = (ProcessPaymentHome)
initialContext.lookup(�java:comp/env/ejb/pphome�);
Which exceptions must be declared in the signatures of the methods contained in the ProcessPaymentHome interface?
Choices
A. RemoteException
B. FindException
C. Any application specific exception
D. CreateException
E. RuntimeException
Correct choice:
C; D
It assert that the CreateException is mandatory for create<METHOD> in session bean's home interface...

Answer my own old question 
The CreateException need not to be defined to be thrown in the home interface for session bean.

The rule you have stated is regarding the ejbCreate() methods in the session bean class. However, in the case of create() methods in the home interface of a session bean, the specification clearly states:
"The throws clause must include javax.ejb.CreateException".
Please check out Section 7.10.8 of the Specs.
