Getting org.xml.sax.SAXNotRecognizedException in Java mapping. Help!

Question

Hi Experts
   I have written a java code for schema validating XI message.
my java code:
import java.io.FileInputStream;
import java.io.FileOutputStream;
import com.sap.aii.mapping.api.StreamTransformation;
import java.io.*;
import java.util.Map;
import javax.xml.parsers.*;
import org.xml.sax.*;
import org.xml.sax.helpers.*;
public class P2PValidation extends DefaultHandler implements StreamTransformation{
     private Map map;
     private OutputStream out;
     //Constants when using XML Schema for SAX parsing.
     static final String JAXP_SCHEMA_LANGUAGE =
     "http://java.sun.com/xml/jaxp/properties/schemaLanguage";
     static final String W3C_XML_SCHEMA =
     "http://www.w3.org/2001/XMLSchema";
     static final String JAXP_SCHEMA_SOURCE =
     "http://java.sun.com/xml/jaxp/properties/schemaSource";
     public void setParameter (Map param){
          map = param;
     public void execute (InputStream in, OutputStream out)
     throws com.sap.aii.mapping.api.StreamTransformationException {
        DefaultHandler handler = this;
          SAXParserFactory factory = SAXParserFactory.newInstance();
          // Obtain an object of class javax.xml.parsers.SAXParser,
         factory.setNamespaceAware(true);
         factory.setValidating(true);
          try {
               SAXParser saxParser = factory.newSAXParser();
               // Setup the schema file
               //saxParser.setProperty(JAXP_SCHEMA_LANGUAGE, W3C_XML_SCHEMA);
               //saxParser.setProperty(JAXP_SCHEMA_SOURCE, new File("IOReqMsgSchema.xsd"));
               saxParser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaLanguage", "http://www.w3.org/2001/XMLSchema");
               saxParser.setProperty("http://java.sun.com/xml/jaxp/properties/schemaSource", new File("IOReqMsgSchema.xsd"));
              //System.out.println("Parsing");
              this.out = out;
               saxParser.parse(in, handler);
          catch (Exception t){
               t.printStackTrace();
     private void write (String s) throws SAXException{
          try{
               out.write(s.getBytes()); out.flush();
          catch (IOException e){
               throw new SAXException("I/O error", e);
     public void startDocument () throws SAXException{
          write("<?xml version=\"1.0\" encoding=\"UTF-8\"?>");
          write("<ns0:ValidInternalOrder xmlns:ns0=\"http://www.xyz.com/Gopal\">");
     public void endDocument () throws SAXException {
          write("</ns0:ValidInternalOrder>");
          try { out.flush();
          catch (IOException e) {
               throw new SAXException("I/O error", e);
     public void startElement (String namespaceURI, String sName, String qName, Attributes attrs)
     throws SAXException {
        System.out.println("sName="sName" qName="+sName);
            if(sName.equals(qName))
               write("<"sName">");
     public void endElement (String namespaceURI, String sName, String qName) throws SAXException {
          if(sName.equals(qName))
               write("</"sName">");
     public void characters (char buf[], int offset, int len)
     throws SAXException {
          String s = new String(buf, offset, len);
          write (s);
     public void error(SAXParseException se) throws SAXException {
          throw se;
But when I run the code in my local machine or in Xi i am getting the error:
org.xml.sax.SAXNotRecognizedException:
        at com.inqmy.lib.xml.parser.SAXParser.setProperty(SAXParser.java:111)
        at com.inqmy.lib.jaxp.SAXParserImpl.setProperty(SAXParserImpl.java:51
        at P2PValidation.execute(P2PValidation.java:38)
What is wrong with the properties I have set for schema validatation?
//Constants when using XML Schema for SAX parsing.
     static final String JAXP_SCHEMA_LANGUAGE =
     "http://java.sun.com/xml/jaxp/properties/schemaLanguage";
     static final String W3C_XML_SCHEMA =
     "http://www.w3.org/2001/XMLSchema";
     static final String JAXP_SCHEMA_SOURCE =
     "http://java.sun.com/xml/jaxp/properties/schemaSource";
Kindly help me understand how to correct this error. What are the correct values for properties?
Please help! URGENT!!!
Thanks
Gopal
