Я модернизируюсь от struts-2.3.24.1 до struts-2.3.28, и при этом пришлось обновлять плитки с 2.1.2 до 2.2.2. Я развертываю на WebLogic Server 12.1.3. Мое приложение построено без ошибок с использованием Maven 3, однако, когда я раскрываю, он генерирует следующие ошибки:Struts2-tiles-plugin 2.3.28 - StrutsTilesListener throws NullPointerException
<User defined listener org.apache.struts2.tiles.StrutsTilesListener failed: java.lang.NullPointerException.java.lang.NullPointerException
at java.io.File.<init>(Unknown Source)
at org.apache.struts2.tiles.StrutsWildcardServletTilesApplicationContext.<init>(StrutsWildcardServletTilesApplicationContext.java:53)
Ничто не изменилось в применении, так как он работал с распорками 2.3.24.1. Есть файлы .jsp в местоположении, указанном в файле -filess.fml. Я испробовал много разных подходов, чтобы исправить это, но продолжаю получать ту же ошибку. Я еще не видел этого конкретного вопроса, который обсуждался ранее. Что еще мне нужно изменить с его конкретным обновлением? Что мне не хватает?
Спасибо,

Edit: это не связана с чем вопрос Исключение нулевого указателя ссылки в комментариях, потому что это проблема с перекладинами плитки.
Редактировать 3/31/2016: Я включил удаленную отладку и обнаружил, что контекст имеет все соответствующие пути (см. Рисунок ниже). Однако строка 53 StrutsWildcardServletTilesApplicationContext.java: context.getRealPath() возвращает значение null, так как не может получить абсолютный путь к этому ресурсу. Контекстный путь также корректен в контексте объекта. Я читал, что функция getRealPath() может возвращать null, если она не может перевести виртуальный путь в реальный путь, который возникает, когда файлы поступают из .war. Как это исправить?
Попробуйте отказаться от '', если это не поможет зарегистрировать ошибку в JIRA https://issues.apache.org/jira/browse/WW –
Обновить dtd-s, drop context-param , убедитесь, что на сервере нет старых версий. Отлаживайте приложение, чтобы узнать, что такое null. –
