Tutorials : Schema Validation with JAXP or JDOM :

Validating with the JAXP 1.3 Validation API

import javax.xml.validation.*;

SchemaFactory factory=SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
Schema schema=factory.newSchema(new File("c:/schemas/catalog.xsd"));

To create a Validator object from a Schema object:

Validator validator=schema.newValidator();

private class ErrorHandlerImpl extends DefaultHandler	
   {		
       public boolean  validationError = false;	
       public SAXParseException saxParseException=null;
       
       public void error(SAXParseException exception) throws SAXException	
       {
           validationError = true;	
           saxParseException=exception;
       }		
       public void fatalError(SAXParseException exception) throws SAXException		
       {		
            validationError = true;	
            saxParseException=exception;	
       }		
       public void warning(SAXParseException exception) throws SAXException		
       {		
       }	
   }

ErrorHandlerImpl errorHandler=new ErrorHandlerImpl();
validator.setErrorHandler(errorHandler);

StreamSource streamSource=new StreamSource(xmlDocument);
validator.validate(streamSource);

Listing 4 shows how to validate using the J2SE 5.0 validation API.

Run the XMLSchemaValidator.java application in your command line or your Java IDE. Here's what the output should be:
