...that I can sprinkle EclipseLink "annotations" in an eclipselink-orm.xml file located in META-INF (or anywhere else).
Do I understand correctly that the order of evaluation will be, without any other configuration on my part:
Annotations first
JPA META-INF/orm.xml next
META-INF/eclipselink-orm.xml last
...?
I'm looking to make use of EclipseLink's type conversion features when EclipseLink is installed as the persistence provider, but I don't want to do this via annotations, since I don't want to drag along the EclipseLink jars only to find out that someone is installing my code in a Hibernate installation. So for boolean columns, for example, I want to indicate in eclipselink-orm.xml that a particular Converter should be used. Am I correct that the best way to do this non-intrusively is to sparsely populate a META-INF/eclipselink-orm.xml file with only those mappings where EclipseLink extensions are being used?
