Now can some one help me write the java code that will take these as input and give proper output like if the XML doc is a valid doc as per the schema i specified...

Thanks...

A simple example using JAXP:

import java.io.File;
import java.io.IOException;

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 XMLValidator {
    public void validateXML(final String schemaPath, final String xmlToValidatePath) throws SAXException, IOException {

        SchemaFactory schemaFactory = SchemaFactory.newInstance(XMLConstants.W3C_XML_SCHEMA_NS_URI);
        Source schemaSource = new StreamSource(new File(schemaPath));
        Schema schema = schemaFactory.newSchema(schemaSource);

        Validator validator = schema.newValidator();
        validator.validate(new StreamSource(xmlToValidatePath));
    }
}
