In the O'Reilley EJB book, they present a good solution to this. You
*don't* want to use an interface that extends EJBObject with the Remote
interface, because EJBObject does a lot of stuff that isn't really
pertinent to the functioning of the remote interface. You do want to
create a business logic interface that contains all of your business
methods for the EJB, but it shouldn't extend EJBObject. Instead, both your
bean and the remote interface should utilize it.
So, if you created the business interface and called it CommonBusiness, you
would have:
public interface Account extends CommonBusiness, EJBObject (for the Remote
interface)
public class AccountBean implements CommonBusiness, EntityBean (for the
home interface).
