Java EE (Java Enterprise Edition) General Discussion

i've searched on how to parse xml against xsd,dtd,etc.. without the needs of internet connection..
but unfortunately, only the xsd file can be set locally and still there needs the internet connection for the other features, properties.

XML: GML file input from gui
XSD: input from gui

javax.xml

package demo;

import java.io.File;
import java.io.IOException;
import java.net.MalformedURLException;
import java.net.URL;

import javax.xml.XMLConstants;
import javax.xml.transform.Source;
import javax.xml.transform.stream.StreamSource;
import javax.xml.validation.Schema;
import javax.xml.validation.SchemaFactory;
import javax.xml.validation.Validator;

import org.xml.sax.SAXException;

public class Sample1WithJavaxXML {

	public static void main(String[] args) {
		URL schemaFile = null;
		try {
			//schemaFile = new URL("http://java.sun.com/xml/ns/j2ee/web-app_2_4.xsd");
			File file0 = new File("AppSchema-C01-v1_0.xsd");
			schemaFile = new URL(file0.toURI().toString());
		} catch (MalformedURLException e1) {
			// TODO Auto-generated catch block
			e1.printStackTrace();
		}
		//Source xmlFile = new StreamSource(new File("web.xml"));
		Source xmlFile = new StreamSource(new File("C01.xml"));
		SchemaFactory schemaFactory = SchemaFactory
		    .newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
		
		//File file1 = new File("XMLSchema.dtd");
		//SchemaFactory schemaFactory = SchemaFactory
			//.newInstance("javax.xml.validation.SchemaFactory:XMLSchema.dtd");
		
		Schema schema = null;
		
		try {
			schema = schemaFactory.newSchema(schemaFile);
		} catch (SAXException e1) {
			// TODO Auto-generated catch block
			e1.printStackTrace();
		}
		Validator validator = schema.newValidator();
		try {
		  validator.validate(xmlFile);
		  System.out.println(xmlFile.getSystemId() + " is valid");
		} catch (SAXException e) {
		  System.out.println(xmlFile.getSystemId() + " is NOT valid");
		  System.out.println("Reason: " + e.getLocalizedMessage());
		} catch (IOException e) {
			// TODO Auto-generated catch block
			e.printStackTrace();
		}
	}
}
