XNI and DOMParser 2003-01-29 - By Brian Madigan
using Xerces 2.2.1, the following code throws a null
pointer exception from somewhere inside the DOMParser.
XMLParserConfiguration config =
new CSVParserConfig( );
org.apache.xerces.parsers.DOMParser parser =
new
org.apache.xerces.parsers.DOMParser (config);
java.net.URL url =
TestParserConfiguration.class.getResource(filename);
parser.parse(new XMLInputSource(null,
url.toExternalForm( ), null));
--->stack trace
java.lang.NullPointerException

The same code using the SAXParser runs fine.
CSVParserConfig is the example found in the XNI
manual, with a few modifications to allow it to build
using 2.2.1. Any ideas?
