core specs :-
If bean class implements a single interface, that interface is assumed to be the business
interface of the bean. This business interface will be a local interface unless the
interface is designated as a remote business interface by use of the Remote annotation
on the bean class or interface or by means of the deployment descriptor.

Now here is a question:
public interface ManageEmployee{
void AddEmployee(Employee emp)
public class ManagerEmployeeBean implements ManagerEmployee
void AddEmployee(Employee emp)

Choose one:
1.ManagerEmployeeBean exposes ManagerEmployee interface as its Local Buss interface.
2.ManagerEmployeeBean does not expose ManagerEmployee as its buss interface.
