metamodel

问题 In the spirit of type safety associated with the CriteriaQuery JPA 2.0 also has an API to support Metamodel representation of entities. Is anyone aware of a fully functional implementation of this API (to generate the Metamodel as opposed to creating the metamodel classes manually)? It would be awesome if someone also knows the steps for setting this up in Eclipse (I assume it\'s as simple as setting up an annotation processor, but you never know). EDIT: Just stumbled across Hibernate JPA 2
