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

Good Luck.

One possibality of getting this error message because u may be using the
old version of Xerces, so download the latest version of Xerces
and keep the new xerces.jar in ur classpath.

i think this will solve ur problem

Vijay

Hi,
I am new validating xml with schema. I get the
following error message when i try to validate xml:

org.xml.sax.SAXNotRecognizedException:
http://apache.org/xml/feature
s/validation/schema-full-checking
Error: org.xml.sax.SAXParseException: Document root
element "PERSON
", must match DOCTYPE root "null".
Error: org.xml.sax.SAXParseException: Document is
invalid: no gramm
ar found.
java.lang.NullPointerException

I know the xml document i have is valid. 
the xml i have is:

<?xml version="1.0" encoding="UTF-8"?>
<PERSON NAME="XXX"
xmlns:xsi="http://www.w3.org/2001/XMLSchema-instance"
xsi:noNamespaceSchemaLocation="mySchema.xsd">
<COUNTRY>countryName</COUNTRY>
<COUNTRY>countryName</COUNTRY>
</PERSON>

schema for it is:

<?xml version="1.0" encoding="UTF-8"?>
<xs:schema xmlns:xs="http://www.w3.org/2001/XMLSchema"
elementFormDefault="qualified">
<xs:element name="PERSON">
<xs:complexType>
<xs:sequence>
<xs:element name="COUNTRY"
type="xs:string"
maxOccurs="unbounded"/>
</xs:sequence>
<xs:attribute name="NAME" type="xs:string"
use="required"/>
</xs:complexType>
</xs:element>
</xs:schema>

The code i am using to validate is:

import org.apache.xerces.parsers.DOMParser;
import org.apache.xerces.parsers.SAXParser;
import org.xml.sax.ErrorHandler;
import org.xml.sax.SAXException;
import org.xml.sax.SAXParseException;
import org.xml.sax.SAXNotRecognizedException;
import org.xml.sax.SAXNotSupportedException;
import java.io.IOException;

import java.io.File;

// A Valdating DOM Application
// with registered Error Handlers
public class SchemaValidate implements ErrorHandler {

// Constructor
public SchemaValidate (String xmlFile) {

// Create a Xerces DOM Parser
DOMParser parser = new DOMParser();
//SAXParser parser = new SAXParser();
//MyResolver resolver = new MyResolver();

// Turn Validation on
try {

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

//parser.setProperty("http://apache.org/xml/properties/schema/external-n
oNamespaceSchemaLocation",
"ebxml.xsd");

//parser.setEntityResolver(resolver);

parser.setFeature("http://apache.org/xml/features/validation/schema",fal
se);

parser.setFeature("http://apache.org/xml/features/validation/schema-full
-checking",false);

parser.setFeature("http://apache.org/xml/features/validation/dtd",false)
;
}
catch (SAXNotRecognizedException e) {
System.err.println (e);
}
catch (SAXNotSupportedException e) {
System.err.println (e);
}

// Register Error Handler
parser.setErrorHandler (this);

// Parse the Document
try {
parser.parse(xmlFile);
}
catch (SAXException e) {
System.err.println (e);
}
catch (IOException e) {
System.err.println (e);
}
catch (Exception e) {
System.err.println (e);
}

}

// Warning Event Handler
public void warning (SAXParseException e)
throws SAXException {
System.err.println ("Warning: "+e);
}

// Error Event Handler
public void error (SAXParseException e)
throws SAXException {
System.err.println ("Error: "+e);
}

// Fatal Error Event Handler
public void fatalError (SAXParseException e)
throws SAXException {
System.err.println ("Fatal Error: "+e);
}

// Main Method
public static void main (String[] args) {
SchemaValidate validatingDOM = new
SchemaValidate("D:\\tmp\\myxml.xml");
}
}
