如果使用EJB3 JPA，我是否需要hibernate？(If using EJB3 JPA , do I need hibernate?)

 我知道JPA只是一个标准，使用它你需要一个实现，如Hibernate3.2，我的问题是：EJB3是否带有JPA的实现，还是我还需要除了EJB3之外的hibernate等实现？ 如果你能指出我的任何有用的教程，这将是伟大的:) 
 
 谢谢 

I know that JPA is just a standard and to use it you need an implementation such as Hibernate3.2 , My question is : does EJB3 come with an implementation of JPA or I still need implementation such as hibernate to use besides EJB3 ? If you can point me to any useful tutorial on this it will be great :)
 
Thanks
