How do you get MOXy oxml mapping file to recognise static classes

[DanielL]

Using MOXy I can flatten parts of my object model in my json outputi.e \[code\]<java-type name="Medium"> <java-attributes> <xml-element java-attribute="trackList" xml-path="."/> </java-attributes></java-type>\[/code\]but when I want to fold in a class that is a child of a static class as follows\[code\]<java-type name="Medium.TrackList"> <java-attributes> <xml-element java-attribute="artistList" xml-path="."/> </java-attributes></java-type>\[/code\]it complains \[code\]Exception Description: Could not load class [Medium.TrackList] declared in the external metadata file. Please ensure that the class name is correct, and that the correct ClassLoader has been set. at org.eclipse.persistence.exceptions.JAXBException.couldNotLoadClassFromMetadata(JAXBException.java:376) at org.eclipse.persistence.jaxb.JAXBContext$TypeMappingInfoInput.getXmlBindingsClasses(JAXBContext.java:979) at org.eclipse.persistence.jaxb.JAXBContext$TypeMappingInfoInput.createContextState(JAXBContext.java:879) at org.eclipse.persistence.jaxb.JAXBContext.<init>(JAXBContext.java:157)\[/code\]How do I resolve this ?
