not sure what's wrong but this jaxp code works for me:
SAXParserFactory parserFactory = SAXParserFactory.newInstance();
parserFactory.setNamespaceAware(true);
parserFactory.setValidating(true);
parserFactory.setFeature("http://apache.org/xml/features/validation/schema";, true);
SAXParser parser = parserFactory.newSAXParser();
XMLReader xmlReader = parser.getXMLReader();
xmlReader.setProperty("http://apache.org/xml/properties/schema/external-schemaLocation";,
"http://schemas.xmlsoap.org/soap/envelope/ "+schema);
xmlReader.setErrorHandler(errorHandler);
xmlReader.parse(new InputSource(reader));
hth,
