NullPointerException at org.apache.crimson.parser.Parser2.parseInternal
I've tried to use JavaTM API for XML Processing (JAXP), particulary default SAX parser,
which is embeded into JAXP.
I downloaded jaxp-1_1.zip file from http://java.sun.com/xml/download.html, extacted it
and included crimson.jar, jaxp.jar and xalan.jar to java CLASSPATH.
After that I'd tried to parse XML document
with following code
// prepare SAX parser
SAXParserFactory factory = SAXParserFactory.newInstance();
DefaultHandler handler = new XMLHandler();
try {
// Create a JAXP SAXParser
SAXParser saxParser = factory.newSAXParser();
// url
File file = new File( fileName );
String url = file.toURL().toString();
System.out.println( "URL: " + url );
// parse
saxParser.parse( url, handler );
} catch (Exception ex) {
ex.printStackTrace();
throw ex;
}
and obtained the message below
java.lang.NullPointerException
