The eclipselink-orm.xml file defines object-relational mapping metadata for EclipseLink. It is built from the existing orm.xml file which makes it more intuitive, requires minimum configuration, and makes it easy to override.
For more information, see:
- Section 12.2 "XML Overriding Rules" in the JPA Specification
-
http://wiki.eclipse.org/EclipseLink/UserGuide/JPA/Basic_JPA_Development/Configuration/JPA/orm.xml
The schema for EclipseLink is eclipselink_orm_X_X.xsd where X_X is the current EclipseLink version number (such as 2_4 for 2.4). All EclipseLink schemas are available from http://wiki.eclipse.org/EclipseLink/XSDs.
