Persistence Units

Column Display     Related Tasks     Related Topics

This table lists the persistence units defined for this module.

Persistence units are defined in persistence.xml. Persistence units define a repository for persisting java objects. Your application specifies the name of the persistence unit to be used. An application or module can utilize different persistence implementations. If you are implementing the Oracle Kodo persistence implementation, then you can configure additonal attributes in persistence-configuration.xml.

Both persistence.xml and persistence-configuration.xml can be configured at either the deployment or module level.

A module may contain one persistence.xml/persistence-configuration.xml pair that defines module-scoped persistence units. An EAR may contains multiple persistence-specific .jar files, each of which can contain a persistence.xml/persistence-configuration.xml pair.
