In EclipseLink 1.0 the new eclipselink-orm.xml mapping file is introduced (See bug 200040). This mapping file can be used in place of JPA's standard mapping file or can be used to override a JPA mapping file. In additional to allowing all of the standard JPA mapping capabilities it also includes advanced mapping types and options.

XML Configuration

The EclipseLink ORM schema (eclipselink_orm_1_0.xsd) can be used with the following header:

<?xml version="1.0" encoding="windows-1252" ?>
<entity-mappings xsi:schemaLocation="http://www.eclipse.org/eclipselink/xsds/orm xsd/eclipselink_orm_1_0.xsd"
	version="1.0" 
	xmlns="http://www.eclipse.org/xml/ns/persistence/orm"
	xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance">

Configuring usage in persistence.xml

A persistence unit can use one or more of these mapping files in the same way a standard JPA ORM mapping XML file can be used. The default location of
