How to append html formatted text to JPaneText?

Question

Hi,
I'm trying to append html to JPaneText and I can't do it. My code is below:
import java.awt.*;
import javax.swing.*;
import javax.swing.text.html.HTMLEditorKit;
import javax.swing.text.html.*;
import javax.swing.text.*;
public
class GUI
extends JFrame {
     JTextPane wynikTxtAre = new JTextPane();
     JScrollPane suwak = new JScrollPane(wynikTxtAre);
     JPanel panelSrodek = new JPanel();
     HTMLDocument doc;
     HTMLEditorKit kit = new HTMLEditorKit();
     public GUI()
super.setSize(640, 480);
super.setDefaultCloseOperation(JFrame.EXIT_ON_CLOSE);
wynikTxtAre.setEditable(false);
wynikTxtAre.setDocument(kit.createDefaultDocument());
doc = (HTMLDocument)wynikTxtAre.getDocument();
suwak.setPreferredSize(new Dimension(600, 400));
panelSrodek.add(suwak);
super.getContentPane().setLayout(new BorderLayout());
super.getContentPane().add("Center", panelSrodek);
super.setVisible(true);     
     public static void main (String [] args) {
          GUI g = new GUI();
          try {
     Style style = g.doc.addStyle("StyleName", null);
     StyleConstants.setItalic(style, true);
     StyleConstants.setFontSize(style, 30);
     StyleConstants.setBackground(style, Color.blue);
     StyleConstants.setForeground(style, Color.white);
     // Append to document
     g.kit.insertHTML(g.doc, g.doc.getLength(), "tekxt", 1, 1, HTML.Tag.B);
     //g.doc.insertString(g.doc.getLength(), "<b>Some Text</b>", style);
     } catch (Exception e) {
          System.out.println(e.getMessage());
If i use insertHTML method then there is no text on the text area.
If i use insertString method then text appear but it doesn't resolve html tags.
Please help.

I did something like this:
public
class GUI
extends JFrame {
//previous code - no changes
     public static void main (String [] args) {
          GUI g = new GUI();
          StringBuffer buf = new StringBuffer();
          try {
     buf.append("<b>bb</b>");
     buf.append("<b>ccc</b>");
     // First append to document
     g.pane.setText(buf.toString());
//Second append
     buf.append("<b>ddddd</b>");
     g.pane.setText(buf.toString());
     } catch (Exception e) {
          System.out.println(e.getMessage());
I know that this method is not smart and doesn't look good, but it works.
If you know how to append html using HTMLEditorKit and HTMLDocument please write some example.
