This is in line with what we have set as our implementation strategy for all of our EJBs. package import . import . The TimeEntry bean holds a single time entry. TimeEntryLocal is the local interface through which local clients access the underlying entity bean. public interface TimeEntryLocal extends EJBLocalObject TimeEntryInt
