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.
