This kind of error happens when some of the property/message files are
missing. Are you using jars from Xerces binary, or building the classes
from the source code?

PM
Please respond to
xerces-j-user
I'm having a bit of the same, yet _not_ resolved...even when I added
the setFeature() methods as within your email.
Am I possibly using the wrong base class?
I'm using:
Xerces 2.2.0
Java2 SDK 1.3.1
I keep getting the Exception: java.lang.ExceptionInInitializerError
Code and output follows...
Here's my code:
import org.xml.sax.*;
import org.xml.sax.helpers.*;
...
import javax.xml.parsers.*;
import org.apache.xerces.jaxp.*;
public abstract class TypeHandler extends DefaultHandler
{
...
private static final String FLAG_VALIDATE =
"http://xml.org/sax/features/validation";;
private static final String FLAG_SCHEMA =
"http://apache.org/xml/features/validation/schema";;
static final String JAXP_SCHEMA_LANGUAGE =
"http://java.sun.com/xml/jaxp/properties/schemaLanguage";;
static final String W3C_XML_SCHEMA =
"http://www.w3.org/2001/XMLSchema";;
protected static String schemaSource;
static final String JAXP_SCHEMA_SOURCE =
"http://java.sun.com/xml/jaxp/properties/schemaSource";;
public void parse( String filename ) throws java.io.IOException,
org.xml.sax.SAXException, org.xml.sax.SAXParseException
{
try
{
log.debug( "file:" + filename );
InputStream in = new BufferedInputStream(new
FileInputStream( filename ));
InputSource source = new InputSource( in );
SAXParserFactory spf = SAXParserFactory.newInstance();
spf.setNamespaceAware( true );
spf.setValidating( true );
SAXParser sp = spf.newSAXParser();
sp.getXMLReader().setFeature(FLAG_VALIDATE, true);
sp.getXMLReader().setFeature(FLAG_SCHEMA, true);
//sp.setProperty(
org.apache.xerces.jaxp.JAXPConstants.JAXP_SCHEMA_LANGUAGE,
org.apache.xerces.jaxp.JAXPConstants.W3C_XML_SCHEMA );
//sp.setProperty(
org.apache.xerces.jaxp.JAXPConstants.JAXP_SCHEMA_SOURCE,
"file://c:/!dev/omni/xsd/IesVendor.xsd" );
log.info( "parse started." );
sp.parse( source, this );
log.info( "parse complete." );
}
catch( Throwable t )
{
log.warn( t.toString() );
t.printStackTrace();
}
}
}
Here's the output:
...
4216 INFO [main] (TypeHandler.java:95) - parse started.

Thank you in advance.
Thank you.
