Re: [castor-user] unable to find FieldDescriptor for 'body' in ClassDescriptor of exception

Can you please switch to using an Unmarshaller instance rather than the static method on Unmarshaller ?

Hi,

Please help me on this. I got tired trying this. I am trying to unmarshall
an xml file and I see the output as "null"

Here is  my Java code snippet.
======================
        public class Test3 {
          public static void main(String args[]) throws MappingException,
XMLException, ValidationException {
            try {
                Log log =LogFactory.getLog(ExceptionTest.class);

                
                 Exception exception =
(Exception)Unmarshaller.unmarshal(Exception.class, new
FileReader("SampleXML.xml"));
log.info(exception.getBody()); 
                 log.info(exception.getEnvelope());
} catch (IOException e) { 
              System.out.println(e.toString() );
            }
        }
        }

And I see the output as ..
