Thanks for your response. Could you let me know how the schema location
string passed to the validate method looks like? I learned from other
sources saying that you have to pass in something like "part1 part2" with a
space in between.
Plus, my XmlReader was created by the factory using SAXParser as the class.
I did similar thing as to set the features and set the property. I got the
following error:

It'd be greatly appreciated if you can point me to the right direction.

Have a look at the following code: note: it is an example, you can modify
it to meet your specific needs.
package com.appresso.dataspider.adapter.sap.common;
import org.xml.sax.ErrorHandler;
import org.xml.sax.SAXException;
import org.xml.sax.SAXParseException;
import org.xml.sax.InputSource;
import org.apache.xerces.parsers.SAXParser;
import java.io.IOException;
public class XMLValidator {
private static final XMLValidator xmlValidator = new
XMLValidator();
public static XMLValidator getInstance(){
return xmlValidator;
}
private XMLValidator(){
}
public void validate(InputSource in, String schemaLocation, String
strNamespace)
throws SAXException, IOException
{
SAXParser reader = new SAXParser();
// Request validation
reader.setFeature("http://xml.org/sax/features/validation";, true);
//set the parser's property: the target namespace, and schema
location
if(!strNamespace.equals(""))
reader.setProperty("http://apache.org/xml/properties/schema/external-schemaL
ocation",
strNamespace+" "+schemaLocation);
else
reader.setProperty("http://apache.org/xml/properties/schema/external-noNames
paceSchemaLocation",
schemaLocation);
// Register the error handler
reader.setErrorHandler(new MyErrorHandler());
reader.parse(in);
}
}
class MyErrorHandler implements ErrorHandler {
public void warning(SAXParseException exception) {
String errorReport = "**Parsing Warning**\n" +
" Line: " +
exception.getLineNumber() + "\n" +
" URI: " +
exception.getSystemId() + "\n" +
" Message: " +
exception.getMessage();
// We only give information when a warning arises.
System.out.println(errorReport);
}
public void error(SAXParseException exception) throws SAXException {
String errorReport = "**Parsing Error**\n" +
" Line: " +
exception.getLineNumber() + "\n" +
" URI: " +
exception.getSystemId() + "\n" +
" Message: " +
exception.getMessage();
System.out.println(errorReport);
throw new SAXException(errorReport);
}
public void fatalError(SAXParseException exception) throws SAXException
{
String errorReport = "**Parsing Fatal Error**\n" +
" Line: " +
exception.getLineNumber() + "\n" +
" URI: " +
exception.getSystemId() + "\n" +
" Message: " +
exception.getMessage();
System.out.println(errorReport);
throw new SAXException(errorReport);
}
}
