XML Schema Validation and importing different encoding schema

Following is a simple code which shows importing an different encoding xml schema into a different encoding xml schema. In the following example Book.xsd imports Age.xsd which has UTF-16 encoding. Following example also shows XML Schema Validation

XMLValidationSample.java
import java.io.IOException;
import org.xml.sax.InputSource;
import org.xml.sax.XMLReader;
import org.xml.sax.SAXException;
import javax.xml.parsers.SAXParser;
import javax.xml.parsers.SAXParserFactory;
import org.xml.sax.SAXParseException;
import javax.xml.parsers.ParserConfigurationException;
public class XMLValidationSample {
public static void main(String args[]) {
try{
String book = "Book.xsd", first = "first.xsd", last = "last.xsd", age = "age.xsd";
String[] schemas = {book, first, last, age};
SAXParserFactory factory = SAXParserFactory.newInstance();
factory.setNamespaceAware( true);
factory.setValidating( true);
SAXParser parser = factory.newSAXParser();
parser.setProperty( "http://java.sun.com/xml/jaxp/properties/schemaLanguage",
"http://www.w3.org/2001/XMLSchema");
parser.setProperty( "http://java.sun.com/xml/jaxp/properties/schemaSource",
schemas);
XMLReader reader = parser.getXMLReader();
reader.parse( new InputSource( "Book.xml"));
}catch (SAXException e) {
Exception x = e.getException ();
((x == null) ? e : x).printStackTrace (); }
catch (IOException e) {
e.printStackTrace (); }
catch(ParserConfigurationException e){
e.printStackTrace (); }
}
}
