Spring 3 MVC and Tiles 2.2

Question

Я настроил приложение Spring MVC/Hibernate/Tiles. Все работало, пока я не представил компонент Tiles. Я считаю, что у меня есть это право, но я получаю «не может сделать нулевой шаблон» исключение

Вот мой корневой context.xml

Пробовал все - за исключением того, что вы, ребята, могли бы добавить. Опять же, все, казалось, работало и правильно подключалось. Если бы вход отображал страницу входа в систему. Сообщение пользователя/пароля в форме отправил обратный путь в БД и отобразил главную страницу. Как только я подключил Tiles, я не могу перенести первую страницу.

Answer 1

Это плитка.xml или tile.xml?

В файле tiles.xml есть определения Login и Home, которые должны расширять определение шаблона?
