Does anyone have correct answers of sharpen your pencil on pg.547?

Here is the question.


From the list of possible options, select what you, as a bean provider, should do in each of the following scenarios. Assume that they all take place within a business method of a session bean.

Optons (you may use an option more than once)

A. Throw an EJBException
B. Throw a RemoteException
C. Invoke setRollbackOnly()
D. Allow the exception to propagate(in other words, duck it)

Scenarios

1. You catch a checked exception in your ejbActivate() method. The method is not in a transaction.
2. A DivideByZero exception occurs as your business logic is running. You do not have a try/catch for this.
3. You throw a CreateException from your ejbCreate() method, and your realize that you probably cannot safely complete your transaction.
4. You catch a checked exception in a business method and realize that your bean is probably corrupt.



Thanks
Shiang
