javax.persistence.PersistenceException - 无法构建 EntityManagerFactory

Question

我正在尝试使用 Java、EJB、JPA 和 MYSQL 数据库编写应用程序。 Eclipse 版本 - eclipse Indigo 服务器- JBOSS v5.0

当我启动服务器并尝试在服务器上运行我的项目时，它会给出此错误消息

请帮我找出问题所在

我已经将它与 spring 一起使用，而不是与 EJB 一起使用，所以在里面 ，我们必须指定一个提供者，例如 org.hibernate.ejb.HibernatePersistence 也许您缺少类似的东西。
