Who I did validation (was: Errata...) [long]

[Jerzy Puchala <je...@scdi.com>]

First I just started play with Xerces parser.
Like I wrote in previous letter this version is NOT working with 1.1.2
version of Xercers.
There I will include part of code which is working on my machine. 

<MAJOR PROGRAM CLASS>
import com.sun.javadoc.*;

import java.util.Collection;
import java.io.IOException;

import org.w3c.dom.Attr;
import org.w3c.dom.Document;
import org.w3c.dom.Element;
import org.w3c.dom.NamedNodeMap;
import org.w3c.dom.Node;
import org.w3c.dom.NodeList;

import org.apache.xerces.parsers.DOMParser;

import org.xml.sax.SAXException;

public class MyClass2 {
	
public static void main(String arg[]) throws Exception {
  MyClass2 myClass = new MyClass2(arg[0]);
}
	
public MyClass2(String a){
  getWork(a);
}
	
private void getWork(String DDuri) {
  try {
    DOMParser parser = new DOMParser();
    try {
      parser.setErrorHandler(new MyErrorHandler());
 
parser.setFeature("http://apache.org/xml/features/allow-java-encodings",
true);

     parser.setFeature("http://xml.org/sax/features/validation",
true);
				
     parser.parse(DDuri);
     Document doc = parser.getDocument();

//here do something with your document, this is not subject of this
//post 
    }
    catch (SAXException e) {
      e.printStackTrace();
    }
    catch (IOException e) {
      e.printStackTrace();
    }

  }
	
} 
</MAJOR PROGRAM CLASS> 

<MyErrorHandler clas>
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;


public class MyErrorHandler implements ErrorHandler {
	
/** Warning. */
public void warning(SAXParseException ex) {
  System.err.println("[Warning] "+
       getLocationString(ex)+": "+
           ex.getMessage());
}
	
/** Error. */
public void error(SAXParseException ex) {
  System.err.println("[Error] "+
       getLocationString(ex)+": "+
           ex.getMessage());
}
	
/** Fatal error. */
public void fatalError(SAXParseException ex) throws SAXException {
System.err.println("[Fatal Error] "+
    getLocationString(ex)+": "+
        ex.getMessage());
throw ex;
}
	
/** Returns a string of the location. */
private String getLocationString(SAXParseException ex) {
StringBuffer str = new StringBuffer();
		
String systemId = ex.getSystemId();
if (systemId != null) {
  int index = systemId.lastIndexOf('/');
  if (index != -1)
    systemId = systemId.substring(index + 1);
    str.append(systemId);
}
str.append(':');
str.append(ex.getLineNumber());
str.append(':');
str.append(ex.getColumnNumber());
		
return str.toString();
} // getLocationString(SAXParseException):String
}
</MyErrorHandler class>

In additon exact look of line with encoding in my xml is:

<?xml version="1.0" encoding="Cp1252"?>

This line is generated by Deployment Descriptor Editor from Inprise
Application Server, adn I can not send whole one. But this was line
which was responsible for error.

I do not made any mapings and changing in any files. I work on Windows
NT 40 Workstation. I have jdk1.2.2_6.

I have to cut big part of my program from this letter but I belive
that I do not cat out to much. 

Once again I am not work with Xerces long time, and maby this problem
can be solved better way. In addition if there are any lines in the
code which are no nessesery - I am sorry (a specialy in import can be
be too much).

I hope that whis will help somebody. Sorry for my poor english.
