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
