Java 使用Glassfish 4和Netbeans 7.4的Maven项目未解决持久化单元

我使用GlassFish4和NetBeans7.4创建了一个Maven web项目

这是我的pom.xml：

我创建的JDBC资源和池只有一个用户：“root”，没有密码。 这是我的persistence.xml：

org.eclipse.persistence.jpa.PersistenceProvider
jdbc/myprojectjdbc
com.myproject.entity.Board
com.myproject.entity.Category
com.myproject.entity.Message
com.myproject.entity.Myuser
com.myproject.entity.Topic

这是我部署时的服务器日志错误：

嗯，持久化单元“com.sun.ejb.containers.TimerBean/em”似乎有问题，而不是持久化单元……是的。。但不知道如何解决它..如何注入

EntityManager

？无论如何，您是否严格需要排除未列出的实体类？为什么要在

pom.xml

中排除

commonj.sdo

？非常奇怪。无论如何，您不需要定义jpa提供者，如果您不需要使用特定的版本，eclipselink已经随glassfish提供。看看这篇文章，可能会有帮助。
