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:

1. An XML mapping file per package
2. 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">
    <java-types>
        <java-type name="mynamespace.Person">
            <xml-root-element name="person"/>
            <java-attributes>
                <xml-element java-attribute="type" xml-path="bloodType/text()"/>
            </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 ...
