[jdom-interest] schema validation fails after switching from Xerces 2.1.0 to 2.2.0

[Scott Cantor]

As the subject says, none of my XML files and
associated schemas will validate using JDOM B8 with
the Xerces 2.2.0 parser.  Everything worked great
before using Xerces 2.1.0.  I am at a total loss
what's causing this other than it being a problem with
either JDOM B8 or Xerces 2.2.0.  Since I'm using JDOM
as the front end, I thought I'd start here first.

Environment: J2SDK 1.4.0.02 on Windows (also fails on
Solaris).

Test code:

************************
* schematest.java:

import org.jdom.*;
import org.jdom.input.*;
import java.io.*;

public class schematest
{
public static void main(String[] args)
{
try
{
SAXBuilder builder 
= new
SAXBuilder("org.apache.xerces.parsers.SAXParser",true);

builder.setFeature
("http://apache.org/xml/features/validation/schema",true);

builder.setFeature
("http://xml.org/sax/features/validation",true);

builder.setProperty
("http://apache.org/xml/properties/schema/external-noNamespaceSchemaLocation",
 "file:///c:/test/test.xsd");

Document doc = builder.build(new File(args[0]));

System.out.println("loaded");
}
catch (Exception k)
{
   System.out.println("caught: " + k.toString());
   k.printStackTrace(System.out);
}
}
}

************************
* test.xml:

<?xml version="1.0" ?>

<test>

</test>

************************
* test.xsd:

<?xml version="1.0"?> 
<xsd:schema
xmlns:xsd="http://www.w3.org/2001/XMLSchema" 
version="1.0">

<xsd:element name="test" >
    <xsd:complexType>
        <xsd:sequence>
        </xsd:sequence>
    </xsd:complexType>
</xsd:element>

</xsd:schema>

******

Assuming I have the following directory structure:

c:\test
  - jdom.jar
  - schematest.java
  - schematest.class
  - test.xsd
  - test.xml
c:\test\210
  - xercesImpl.jar (Xerces 2.1.0)
  - xmlParserAPIs.jar (Xerces 2.1.0)
c:\test\220
  - xercesImpl.jar (Xerces 2.2.0)
  - xmlParserAPIs.jar (Xerces 2.2.0)

I can do this:

set
classpath=.\jdom.jar;.\210\xercesImpl.jar;.\210\xmlParserAPIs.jar;.
java schematest test.xml

or this:

java
-Xbootclasspath/p:.\210\xercesImpl.jar;.\210\xmlParserAPIs.jar
schematest test.xml

...and it prints out this:

loaded

But if I do this:

set
classpath=.\jdom.jar;.\220\xercesImpl.jar;.\220\xmlParserAPIs.jar;.
java schematest test.xml

or this:

java
-Xbootclasspath/p:.\220\xercesImpl.jar;.\220\xmlParserAPIs.jar
schematest test.xml

...it prints out this:

caught: org.jdom.JDOMException: Error on line 3 of
document file:/C:/test/test.x
ml: cvc-elt.1: Cannot find the declaration of element
'test'.
org.jdom.JDOMException: Error on line 3 of document

Any ideas?
