Hi
From this thread:
https://forums.hibernate.org/viewtopic.php?f=9&t=940193&start=0&sid=1e89fbf703b1748e2d609836272ee8f9it looks like XMLDatabinder/ReverseXMLDatabinder no longer exists in H3. You can't have H2 and H3 resources coexisting on your classpath.
If you are not getting a compile error to resolve 'ReverseXMLDataBinder' itself, you must have legacy hibernate resources on your path.
If you require the XMLDatabinder/ReverseXMLDatabinder then it looks like you may need to revert to H2. Hope this helps.
