Hi I am new to Persistence. I want to use ORM in my project and i want to use JPA. As i am new, i am bit confused whether to use EJB3 entity beans or hibernate. I know both follow JPA. Can i use ejb3 entity beans following jpa without any need of hibernate or i need to use hibernate too. Someone told me that if i am using entity beans 3 still i have to use EntityManager implementation of JPA provided by Hibernate. please help.
