Исключение из потока "main" javax.persistence.PersistenceException: Нет Удерживающий механизм для EntityManager с именем lanceurApplication

Question

Я пытаюсь настроить сохранение с помощью JPA и Hibernate для Java-проекта. Я использую Oracle 11g express для моей базы данных. Я занимаюсь этим уже несколько часов, но независимо от того, что я делаю, я всегда получаю это исключение, когда пытаюсь создать EntityManagerFactory: я нашел немало похожих вопросов относительно этого исключения, но никаких решений, которые я могу добраться до работы. Что я здесь делаю неправильно?

Подробно:

Ошибка я получаю это:

Exception in thread "main" javax.persistence.PersistenceException: No Persistence provider for EntityManager named lanceurApplication

Answer 1

1-удалить все ваши библиотеки баночка

2-добавить их снова Свойства -> Java Build Path -> Добавить файлы JAR

3-Project -> Clean

4-модификация с spring3
