One of the major themes of Java EE 7 and JPA 2.1 is multi-tenancy and EclipseLink, the JPA 2.1 reference implementation, has blazed the trail by shipping support for both multi-tenancy and tenant specific extensions in the Eclipse Indigo release. EclipseLink multi-tenancy enables the use of a single persistence unit by multiple tenants while keeping their data isolated and secure.

JPA2.1 does *not* include multi-tenancy support actually. A long time ago it was considered, but not included. Most JPA implementations provide vendor-specific support for tenancy via a discriminator, not just EclipseLink ("blazing the trail" - which it didn't)
