I am using Spring CastorMarshaller for unmarshalling from xml-> Java.
I want to validate the xml against the xsd before unmarshalling it.

I have enabled validation using the following in castor.properties file.

org.exolab.castor.parser.validation=true

# Comma separated list of SAX 2 features that should be enabled for the
# default parser.
#
org.exolab.castor.sax.features=http://xml.org/sax/features/validation,\
http://apache.org/xml/features/validation/schema,\
http://apache.org/xml/features/valid...-full-checking

# True for parser to support Namespaces.
# Defaults to false.
#
org.exolab.castor.parser.namespaces=true

# Defines the default XML parser to be used by Castor.
org.exolab.castor.parser=com.sun.org.apache.xerces .internal.parsers.SAXParser

The xml file has correct schema defined in xsi:schemaLocation.

But I always get this trace while unmarshal
Caused by: org.xml.sax.SAXParseException: cvc-elt.1: Cannot find the declaration of element 'rankings'.

Appreciate your help.
Thanks in advance.
