EclipseLink-4003 (Eclipse Persistence Services - 2.5.2.v20140319-9ad6abd): org.eclipse.persistence.exceptions.DatabaseException)

Question

У меня есть эта ошибка, но я не знаю, где проблема. Я предполагаю, что eclipseLink- mysql вместе не совпадают. Я использую Tomcat 8.0.27.0 и mysql -connector-java8-5.1.23.jar, но я изменяю файл jar. Я принимаю ошибку. Я не понимаю, где произошла ошибка? Я использовал netbeans 8.2R C. И я думаю, что мои коды очень легко читаются.

Я хочу сделать сущность продукта. затем запишите в базу данных, я использовал jsf и jsp, но просто mysql не подключается.
