org.springframework.oxm.castor.CastorMarshaller
public class CastorMarshaller
Implementation of the Marshaller interface for Castor. By default, Castor does not require any further
configuration, though setting target classes, target packages or providing a mapping file can be used to have more control over the
behavior of Castor.
If a target class is specified using setTargetClass, the CastorMarshaller can only be
used to unmarshall XML that represents that specific class. If you want to unmarshall multiple classes, you have to
provide a mapping file using setMappingLocations.
Due to limitations of Castor's API, it is required to set the encoding used for writing to output streams. It
defaults to UTF-8.

XMLException to an appropriate exception
from the org.springframework.oxm hierarchy.
A boolean flag is used to indicate whether this exception occurs during marshalling or unmarshalling, since Castor itself does not make this distinction in its exception hierarchy.
ex - Castor XMLException that occuredmarshalling - indicates whether the exception occurs during
marshalling (true), or unmarshalling (false)
