Я изучаю struts 2, и я пытаюсь сделать демо-версию плагина для плагина. И я получил исключение выше. Я нашел ту же тему в org.apache.tiles.TilesException: Attribute 'header' not found in struts2 Но это не помогает. Вот мой код:org.apache.tiles.TilesException: Attribute 'st' not found

И проект (я создал проект с пустой войны, так что вы много банок) 
PS: Я использую самые последние распорки 2 и банки пришли с пакет стойки 2.
Вы доступ к вашему 'baselayout.jsp' напрямую, а не через действие Struts2, и из-за того, что плитки не визуализируются. –
Я назвал его действием, и это сработало. – SmartGoat
