Я работаю над простой демонстрацией Hibernate на сервере FUSE, и я нашел этот пример кода примера в этом github location. Я пытаюсь запустить этот код в FUSE 6.3 с интеграцией Hibernate 4. Я смог установить все необходимые зависимости, но когда я пытаюсь выполнить операцию базы данных, я получаю следующую ошибку.FUSE hibernate application throws Нет сеанса для текущего исключения потока

Это структура проекта, которую у меня есть.
ли кто-нибудь испытывал такого рода вопросов на FUSE зимуют интеграции. Я смог установить проект без каких-либо проблем. Но когда я пытаюсь выполнить операцию базы данных, я получаю эту ошибку.
Возможно, какой-то эксперт поможет мне решить эту проблему.
