persistence.xml

A persistence unit configures various details that are required when you acquire an entity manager. You specify a persistence unit by name when you acquire an entity manager factory.

You configure persistence units in the JPA persistence descriptor file: persistence.xml.

In this file, you can specify the vendor extensions that this reference describes by using a <properties> element.
