Persistence provider
Persistence providers are implementations of the Java Persistence API (JPA) specification and can be deployed in the Java EE compliant application server that supports JPA persistence.
There are two built-in JPA persistence providers for WebSphere Application Server:
| 
|
| IBM WebSphere JPA persistence provider |
|
|
|
| Apache OpenJPA persistence provider |
If an explicit provider element is not specified in the persistence unit definitions, the application server will use the default persistence provider, which is the WebSphere JPA persistence provider.
