EclipseLink supports the use of JAXB with externalized mapping files. These mapping files support specifying the Object-XML binding of JAXB 2.2 annotations plus many of the advanced mapping and configuration options provided by EclipseLink MOXy.

How to use eclipselink-orm.xml
In order to specify the mappings between domain objects and an XSD an application must provide:
- An XML mapping file per package
- A JAXB.properties file specifying EclipseLink as the JAXB implementation
Example Mapping File: /model/eclipselink-oxm.xml
<?xml version="1.0" encoding="US-ASCII"?> <xml-bindings xmlns="http://www.eclipse.org/eclipselink/xsds/persistence/oxm" xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance" xsi:schemaLocation="http://www.eclipse.org/eclipselink/xsds/persistence/orm http://www.eclipse.org/eclipselink/xsds/eclipselink_orm_2_1.xsd" version="2.1"> <java-types> <java-type name="mynamespace.Person"> <xml-root-element name="person"/> <java-attributes> <xml-element java-attribute="name" /> </java-attributes> </java-type> </java-types> </xml-bindings>
Specifying the EclipseLink MOXy Runtime
To specify the EclipseLink MOXy (JAXB) runtime should be used you need to add a file called jaxb.properties in the same package as the domain classes with the following entry.
javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory
Specifying the mapping files
In order to configure EclipseLink MOXy to use the mapping files ...
