Исходное создание SessionFactory не удалось

Question

Я знаю, что этот вопрос задан раньше, но все ответы не исправили мою проблему. Поэтому я прошу у меня в надежде получить помощь от более опытных программистов на Java. Я пытаюсь запустить простой спящий код с hibernate 4, но я получаю ту же ошибку.

Answer 1

Hibernate не может найти jtds Класс драйвера на пути к классу.

Вызванный: java.lang.ClassNotFoundException: Не удалось загрузить запрошенный класс: net.sourceforge.jtds.jdbc.Driver

Убедитесь, что банку jtds на пути к классам так Hibernate может загрузите класс.
