This tag is for questions about the version 1.0 of the Java Persistence API. JPA 1.0 is the first version of the Java Persistence API specification.

JPA 1.0 was released as part of the EJB 3.0 specification under JSR 220, but it can also be used in a Java SE application. JPA was meant to supersede EJB Entity Beans. Entity beans continue to be supported for backward compatibility. Any bean managed by JPA is no longer called an entity bean; instead, it is merely referred as an entity.
