specify alternate JAXB provider

In my Grails app, I want to use EclipseLink as the JAXB provider. I tried adding a file grails-app\conf\jaxb.properties with the contents

javax.xml.bind.context.factory=org.eclipse.persistence.jaxb.JAXBContextFactory

But it seems the default JAXB provider is still being used. I've confirmed that the relevant JARs for EclipseLink are on my runtime classpath.

The jaxb.properties file needs to be added in the same package as your domain classes:
