> I was working recently on the implementation that uses JPA2 meta-model. It was rather surprise to me when I found out that name of the entity on {{EntityType}} is different than name of the entity specified with {{@Entity}} annotation.
> The specification is not explicit about the entity names, so it could be interpreted differently, but I think it is reasonable to implicitly assume that entity name specified with {{@Entity}} is used as entity name with JPA2 meta-model.

> *10.1 Entity*
> The {{Entity}} annotation specifies that the class is an entity. This annotation is applied to the entity
> class.
> The {{name}} annotation element specifies the entity name. If the {{name}} element is not specified, the entity
> name defaults to the unqualified name of the entity class. This name is used to refer to the entity in queries.

> I know that in Hibernate the entity name if FQN of persistent class and the abbreviated name (without the package) can be *only* used within the HQL queries. I guess this was OK prior JPA2 when there was no such think like meta-model.
> This topic has been already discussed several times, but I couldn't find any discussion in the context of JPA meta-model, thus I've decided to create a new ticket. The other issues related to this topic are: HHH-4375, HHH-2597 and HHH-4465.
