XML Parser SAX problem with diacritical letters

[damiannelus]

Hi there,
I used few tutorials from net to build XML Parser. Everything works fine, with small exception. Either system.out or JTextArea doesn't show polish diacritical letters - it's important for me to solve this problem. Anyone have idea, what should be changed?

Code here:

import java.awt.List;
import java.awt.event.ActionEvent;
import java.awt.event.ActionListener;
import java.io.File;
import java.io.FileReader;

import javax.swing.JButton;
import javax.swing.JEditorPane;
import javax.swing.JFileChooser;
import javax.swing.JFrame;
import javax.swing.JPanel;
import javax.swing.JScrollPane;
import javax.swing.JTextArea;
import javax.swing.JTextField;

import org.xml.sax.XMLReader;
import org.xml.sax.Attributes;
import org.xml.sax.InputSource;
import org.xml.sax.helpers.XMLReaderFactory;
import org.xml.sax.helpers.DefaultHandler;


public class MySAXApp extends DefaultHandler implements ActionListener
{
	protected
	JTextArea textArea;
	static JEditorPane jep = new JEditorPane();

    public static void main (String args[])
	throws Exception
    {
    	
	XMLReader xr = XMLReaderFactory.createXMLReader();
	MySAXApp handler = new MySAXApp();
	xr.setContentHandler(handler);
	xr.setErrorHandler(handler);
	final JFileChooser fc = new JFileChooser();
	fc.setMultiSelectionEnabled(true);
	fc.showDialog(fc, "Wybierz pliki do archwizacji");
	File file = fc.getSelectedFile();
	//JEditorPane jep = new JEditorPane();
	


	    FileReader r = new FileReader(file.getAbsolutePath());
	    xr.parse(new InputSource(r));

	    
	    System.out.println(12);
    }


    public MySAXApp ()
    {
    	super();
    	textArea = new JTextArea();
    	JScrollPane scrollingArea = new JScrollPane(textArea);
    	JFrame frame = new JFrame();
    	frame.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
    	
    	//frame.add(textArea);
    	frame.add(scrollingArea);
    	frame.pack();
    	frame.setVisible(true);
    	frame.setSize(300, 200);
    }

    {
	System.out.println("Koniec dokumentu");
	textArea.append("Koniec dokumentu \n");
    }


    public void startElement (String uri, String name,
			      String qName, Attributes atts)
    {
    	if (qName.equalsIgnoreCase("Grupa")){
    		System.out.println(name + " : " +atts.getValue("nazwa"));
    		textArea.append(name + ": " +atts.getValue("nazwa") + "\n");
    	} else if (name.equals("Cena")){
    		System.out.println("nazwa:");
    		textArea.append("\t");
    	}
    }


    public void endElement (String uri, String name, String qName)
    {
    	if(qName.equalsIgnoreCase("Produkt")){
    		System.out.println("\t");
    		//textArea.append("\t");
    		
    	} else if (qName.equalsIgnoreCase("Cena")){

	else
	    System.out.println("Koniec elementu:   {" + uri + "}" + name);*/
    }


    public void characters (char ch[], int start, int length)
    {
    	String toSay = new String(ch, start, length);
	//System.out.print("Wartość pola:    \"");
	for (int i = start; i < start + length; i++) {
	    switch (ch[i]) {
	    case '\\':
		System.out.print("");
		break;
	    case '\"':
		System.out.print("1");
		break;
	    case '\n':
		System.out.print("");
		break;
	    case '\r':
		System.out.print("");
		break;
	    case '\t':
		System.out.print("");
		break;
	    default:
	    	if(ch[i]== 22){
	    		System.out.println(123);
	    	}else
	    		//System.out.print(ch[i]);
	    	//toSay ="" + ch[i];
	    	textArea.append(toSay);

	//textArea.append(toSay);
	System.out.print("");
    }


	@Override

	}

}

1. Make sure, yours source code editor is set to store files in UTF-8 format.
2. Make sure, javac -encoding UTF-8 is used to compile source file.


This way You will have correct encoding in swing and GUI. However I/O streams to console may be incorrect in Windows operating system.

3. Better way: read the i18n (internationalization-localization) guides and follow them.
