XP Для работы по администрированию таблицы Department создаем классы: DepartmentListController; EnterDepartmentController; DeleteDepartmentController; EnterDepartmentValidator; DelName – командный объект для формы выбора удаляемого элемента; DeleteDepartmentController.

XP Добавляем: <bean name="departmentListController" class="com.visualpatterns.timex.controller.DepartmentListC ontroller"> departmentlist

XP Валидаторы: <bean id="deleteDepartmentValidator" class="com.visualpatterns.timex.controller.DeleteDepa rtmentValidator" /> Менеджер: <bean id="departmentManager" class="com.visualpatterns.timex.model.DepartmentM anager" />
