What are the advantages of the Java Persistence API?
The Java Persistence API draws upon the best ideas from persistence technologies such as Hibernate, TopLink, and JDO. Customers now no longer face the choice between incompatible non-standard persistence models for object/relational mapping. In addition, the Java Persistence API is usable both within Java SE environments as well as within Java EE, allowing many more developers to take advantage of a standard persistence API.
