Hi,
I have a orm mapping file. It is in json format instead of xml format.
When I tried to parse it like this

	XMLContext context = new XMLContext(new XMLEntityMappingsMappingProject(XMLEntityMappingsReader.ECLIPSELINK_ORM_NAMESPACE,
				XMLEntityMappingsReader.ECLIPSELINK_ORM_XSD));
		org.eclipse.persistence.jaxb.JAXBContext ctx=new org.eclipse.persistence.jaxb.JAXBContext(context);
		JAXBUnmarshaller unmarshaller = ctx.createUnmarshaller();
		unmarshaller.setProperty("eclipselink.media-type", "application/json");
		return (XMLEntityMappings) unmarshaller.unmarshal(reader);

I got this error


javax.xml.bind.UnmarshalException

I use json since the mapping file will be generated by javascript. I have no problem to marshaller the mapping as json.

Any idea how to workaround this?

Really appreciated.

thanks

Hi Jason,

Try changing your code to do the following:

XMLEntityMappingsMappingProject project = new XMLEntityMappingsMappingProject(XMLEntityMappingsReader.ECLIPSELINK_ORM_NAMESPACE, XMLEntityMappingsReader.ECLIPSELINK_ORM_XSD);
project.getDatasourceLogin().setDatasourcePlatform(new SAXPlatform());
XMLContext context = new XMLContext(project);
