Saxon

Should I expect that my errorhandler be invoked when using a saxsource with saxon, or am I expecting something that I shouldn't? If I use SAXSource with JAXP with Saxon, it appears that my errorhandler is never invoked when there are parse errors regarding DTD validation. But, if I use a TransformerHandler it is invoked. For example: package test; import java.io.StringReader; import javax.xml.transform.ErrorListener; import javax.xml.transform.Transformer; import javax.xml.transform.TransformerException; import javax.xml.transform.TransformerFactory; import javax.xml.transform.sax.SAXSource; import javax.xml.transform.sax.SAXTransformerFactory; import javax.xml.transform.sax.TransformerHandler; import javax.xml.transform.stream.StreamResult; import javax.xml.transform.stream.StreamSource; import net.sf.saxon.TransformerFactoryImpl; import org.xml.sax.ErrorHandler; import org.xml.sax.InputSource; import org.xml.sax.SAXException; import org.xml.sax.SAXParseException; import org.xml.sax.XMLReader; import org.xml.sax.helpers.XMLReaderFactory; public class JaxpParseErrors { private static class MyErrorListener implements ErrorListener { public void error(TransformerException exception) throws TransformerException { System.out.println("ErrorListener(error): " + exception); } public void fatalError(TransformerException exception) throws TransformerException { System.out.println("ErrorListener(fatalError): " + exception); throw exception; } public void warning(TransformerException exception) throws TransformerException { System.out.println("ErrorListener(warning): " + exception); } } private static class MyErrorHandler implements ErrorHandler { public void error(SAXParseException exception) throws SAXException { System.out.println("ErrorHandler(error): " + exception); } public void fatalError(SAXParseException exception) throws SAXException { System.out.println("ErrorHandler(fatalError): " + exception); throw exception; } public void warning(SAXParseException exception) throws SAXException { System.out.println("ErrorHandler(warning): " + exception); } } public static void main(String[] args) throws Exception { JaxpParseErrors j = new JaxpParseErrors(); j.go(); //j.goSax(); } public void go() throws Exception { String xml = "<!DOCTYPE doc [\n" + "<!ELEMENT doc EMPTY>\n" + "]>\n" + "<doc a='b'/>\n"; StringReader ssr = new StringReader(xml); InputSource is = new InputSource(ssr); XMLReader xr = XMLReaderFactory.createXMLReader(); xr.setErrorHandler(new MyErrorHandler()); xr.setFeature("http://xml.org/sax/features/validation", true); SAXSource ss = new SAXSource(xr, is); String xsl = "<transform version='1.0'" + " xmlns='http://www.w3.org/1999/XSL/Transform'&gt;\n" + "<template match='@|node()'>\n" + "<copy><apply-templates select='@|node()'/></copy>\n" + "</template>\n" + "</transform>\n"; StringReader xsr = new StringReader(xsl); StreamSource xs = new StreamSource(xsr); StreamResult sr = new StreamResult(System.out); ErrorListener el = new MyErrorListener(); TransformerFactory tf = new TransformerFactoryImpl(); tf.setErrorListener(el); Transformer trans = tf.newTransformer(xs); trans.setErrorListener(el); trans.transform(ss, sr); } public void goSax() throws Exception { String xml = "<!DOCTYPE doc [\n" + "<!ELEMENT doc EMPTY>\n" + "]>\n" + "<doc a='b'/>\n"; StringReader ssr = new StringReader(xml); InputSource is = new InputSource(ssr); XMLReader xr = XMLReaderFactory.createXMLReader(); xr.setErrorHandler(new MyErrorHandler()); xr.setFeature("http://xml.org/sax/features/validation", true); String xsl = "<transform version='1.0'" + " xmlns='http://www.w3.org/1999/XSL/Transform'&gt;\n" + "<template match='@|node()'>\n" + "<copy><apply-templates select='@|node()'/></copy>\n" + "</template>\n" + "</transform>\n"; StringReader xsr = new StringReader(xsl); StreamSource xs = new StreamSource(xsr); StreamResult sr = new StreamResult(System.out); ErrorListener el = new MyErrorListener(); SAXTransformerFactory tf = new TransformerFactoryImpl(); tf.setErrorListener(el); TransformerHandler th = tf.newTransformerHandler(xs); th.setResult(sr); Transformer trans = th.getTransformer(); trans.setErrorListener(el); xr.setContentHandler(th); xr.setProperty("http://xml.org/sax/properties/lexical-handler", th); xr.parse(is); } } If I use j.go() MyErrorHandler is never invoked, but if I use j.goSax() it is. This is on linux with jdk 1.6.0_11 and saxonb 9.1.0.5. If I remove saxon from the classpath and use TransformerFactory.newInstance(), the error handler is invoked for both methods.
