XMLGrammarBuilder NullPointerException

Hi,
  this may be a simple usage issue, but I'm trying to use XMLGrammarBuilder
for validation of an instance document against a schema. I'm using the
following
command;

java xni.XMLGrammarBuilder -a name.xsd -i name.xml

and get,

C:\XMLSchema>java xni.XMLGrammarBuilder -a name.xsd -i name.xml
java.lang.NullPointerException
        at
org.apache.xerces.parsers.IntegratedParserConfiguration.configurePipe
line(Unknown Source)
        at org.apache.xerces.parsers.DTDConfiguration.reset(Unknown Source)
        at org.apache.xerces.parsers.DTDConfiguration.parse(Unknown Source)
        at org.apache.xerces.parsers.DTDConfiguration.parse(Unknown Source)
        at xni.XMLGrammarBuilder.main(Unknown Source)

Any thoughts?

Platform Windows 2000, JDK 1.4.1_02, xerces Version 2.4, xsd and xml files
below,

Thanks,

Andy
