It gives me the following error:

XML Document has Error:true cvc-elt.1: Cannot find the declaration of element 'SCustomerList'.

public void validateSchema()
{
String schemaUrl = SCHEMA_URL;

factory.setValidating(true);

doc = parser.parse("file:///c:/s-data/sxml.xml");
if(handler.validationError==true)
System.out.println("XML Document has Error:"+handler.validationError+" "+handler.saxParseException.getMessage());
