Please include your source files for your Entity classes which include the
annotations you are using, or include the XML if you are using the orm.xml
to define the mappings.
Just past them into your post, I probably don't need your entire source
file, but at a minimum include the annotations that you specified and
their values, otherwise I have no way to verify or recreate your issue.
It seems the column names you are giving are wrong, or their is a bug in
the auto mapping code if you have not set any.
