New and Noteworthy

Extend Entities

Developers can make their JPA entities or MOXy JAXB beans extensible so that at runtime a set of additional extended mappings can be used.

Support Multiple Tenants

Developers can design and deploy applications where their persistent entities manage entities for multiple tenants in the same application with storage in a shared table.

Externalize Mappings

Developers can now store mappings using a MetadataSource external to the running application so that mapping overrides and extended mappings can be more dynamically integrated into deployed applications.

Multiple Database

Composite Persistence Units (PU) allows developers to access entities in different data sources by composing their PUs together including support for relationships between entities in different databases.
