When I make that change, I now get this error:
org.exolab.castor.xml.MarshalException: cvc-elt.1: Cannot find the
declaration of element 'dataSource'.{File: [not available]; line: 3; column:
52}
dataSource is the top-level element in db-config-sample.xml and is defined
in db-config-1.0.xsd. For some reason, Castor isn't seeing the XSD.
