Piccolo XML Parser for Java

Under Java 5, for

SAXParserFactory f =
SAXParserFactory.newInstance();
f.setValidating(true);

I get:

javax.xml.parsers.ParserConfigurationException: XML
document validation is not supported

That's because the builtin SAXParserFactory now is
com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl
which should be checked for in JAXPSAXParserFactory:

// Try Java 5 built-in
try {
return Class.forName(

"com.sun.org.apache.xerces.internal.jaxp.SAXParserFactoryImpl");
}
catch (ClassNotFoundException e) {
}

// Finally try Crimson, Java 1.4 built-in
try {
return Class.forName(

"org.apache.crimson.jaxp.SAXParserFactoryImpl");
}
catch (ClassNotFoundException e) {
return null;
}
