Setting external-schemaLocation causes java.lang.ClassCastException

           Summary: Setting external-schemaLocation causes
                    java.lang.ClassCastException
           Product: Xerces2-J
           Version: 2.3.0
          Platform: PC
        OS/Version: Windows NT/2K
            Status: NEW
          Severity: Blocker
          Priority: Other
         Component: DOM
        AssignedTo: xerces-j-dev@xml.apache.org
        ReportedBy: bo.esbech@memobase.dk


I have an application that uses Xerces for XML Schema validation. I previously 
used Xerces-2.0.1 but had dissided to upgrade to Xerces-2.3.0. The application 
run without any problem with Xerces-2.0.1 but fails with an 
java.lang.ClassCastException when running with Xerces-2.3.0. I have isolated 
the problem and written a small program that illustrates the problem. The 
program is shown below:

--- xerces_test.java ---
import java.io.*;

import org.xml.sax.SAXException;
import org.xml.sax.*;

import org.w3c.dom.Document;
import org.w3c.dom.DocumentType;
import org.w3c.dom.NamedNodeMap;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;
import org.w3c.dom.Element;
import org.w3c.dom.Text;
import org.apache.xerces.parsers.DOMParser;

import java.util.*;
import java.security.*;

class SOAPErrorHandler implements ErrorHandler {
	private String m_sErrorText = "";
	private boolean m_bSchemaValid = true;

	private void catchError(SAXParseException exception) {
		m_sErrorText += exception.getMessage();
		m_bSchemaValid = false;
	}
	public void error(SAXParseException exception){catchError(exception);}
	public void fatalError(SAXParseException exception){catchError
(exception);}
	public void warning(SAXParseException exception){catchError(exception);}

	public boolean isSchemaValid() { return( m_bSchemaValid );	}
	public String getErrorText() { return( m_sErrorText ); }
}

public class xerces_test {

	public static void main( String args[] ) throws Exception{
		System.out.println( "Tester stated..." );
		DOMParser parser = new DOMParser();
		parser.setFeature("http://xml.org/sax/features/namespaces", 
true);
		parser.setFeature("http://xml.org/sax/features/validation", 
true);
		parser.setFeature
("http://apache.org/xml/features/validation/schema", true);

		// Make sure to validate SOAP elements against XML Shchema.
		String schemaLocation 
= "http://schemas.xmlsoap.org/soap/envelope/ http://intranet/temp/envelope.xsd";
		parser.setProperty
("http://apache.org/xml/properties/schema/external-schemaLocation", 
schemaLocation);

		SOAPErrorHandler err = new SOAPErrorHandler();
	 	parser.setErrorHandler(err);

		System.out.println( "Beginning to parse..." );
		// Parse posted XML and check weather XML comforms with SOAP 
specification.
		try {

			parser.parse( args[0]);
		}catch( SAXParseException e) {
			System.out.println( "Error parsing request. Parser 
returned: " + err.getErrorText() );
			return;
		}

		if( !err.isSchemaValid() ) {
			System.out.println( "XML document does not conform with 
SOAP and/or xsql specifications. Parser returned: " + err.getErrorText() );
			return;
		}
		System.out.println( "Source valid..." );
	}
}

When running with Xerces-2.3.0 i get the folling exception.

Tester stated...
Beginning to parse...
Exception in thread "main" java.lang.ClassCastException:

        at xerces_test.main(xerces_test.java:54)

Line 54 in xerces_test.java is "parser.parse( args[0]);".

The program runs without problems with Xerces-2.2.1 as well.
