I don't think it is a problem with the class/field
mapping in the mapping file. As I mentioned in my
previous e-mail from yesterday: just to make sure
that I was not getting the error because of a problem
with the input xml or the Castor mapping file, I tried
unmarshalling using straight Castor unmarshalling code
(see below) and it works fine with NO errors.
// load castor mapping file
Mapping map = new Mapping();
map.loadMapping(mappingPath);
// Create an instance of Castor's unmarshaller
Unmarshaller unmarshaller = new
Unmarshaller(RunDvpRequestVO.class);
unmarshaller.setMapping(map);
// Create a Reader to the input file to unmarshal from
Reader reader = new FileReader(inputFilePath);
// Unmarshall the input xml into a value object
RunDvpRequestVO runDvpRequest = (RunDvpRequestVO)
unmarshaller.unmarshal(reader);
The code above works fine, and there is no errors. So
obviously the class/field mapping must be correct. It
must be a problem with using the UnmarshalHandler with
the SAX praser. In my case I was using the Xerces SAX
parser.
