PersistenceUnit: jpaData - Невозможно построить EntityManagerFactory

Я создал проект весны и спячки и получил следующее исключение:

Exception in thread "main" org.springframework.beans.factory.BeanCreationException: Error creating bean with name 'entityManagerFactory' defined in class path resource [applicationContext.xml]: Invocation of init method failed; nested exception is javax.persistence.PersistenceException: [PersistenceUnit: jpaData] Unable to build EntityManagerFactory

Любые рекомендации, что я должен изменить в моей entityManagerFactory? Я ценю ваш ответ!

PS: Я просто хочу read на уровне db, а не create, update или delete sth.

ОБНОВИТЬ

Я уже добавил ojdbc6-11.1.0.7.0.jar в buildPath...
