Java EE (Java Enterprise Edition) General Discussion

Hi,

I've developed a class to parse a xml file with SAX.

  static final String JAXP_SCHEMA_LANGUAGE =
   "http://java.sun.com/xml/jaxp/properties/schemaLanguage";
  static final String WC3_XML_SCHEMA =
   "http://www.w3.org/2001/XMLSchema";
  static final String JAXP_SCHEMA_SOURCE =
   "http://java.sun.com/xml/jaxp/properties/schemaSource";

  public static boolean isValidSax(InputStream source, String schema) {
   try {
     SAXParserFactory spf = 
             org.apache.xerces.jaxp.SAXParserFactoryImpl.newInstance();
     spf.setNamespaceAware(true);
     spf.setValidating(true);
     SAXParser sp = spf.newSAXParser();
     sp.setProperty(JAXP_SCHEMA_LANGUAGE, WC3_XML_SCHEMA);
     sp.setProperty(JAXP_SCHEMA_SOURCE, "C:\\letter.xsd");
     MyDefaultHandler dh = new MyDefaultHandler();
     sp.parse(source,dh);
...

My problem is in jrun4 this code works fine but when i put this in IBM WSAD 5.1 i get the following error:

org.xml.sax.SAXNotRecognizedException: http://java.sun.com/xml/jaxp/properties/schemaSource

Anybody knows what happens?

Thanks
