Rendering HTML documents in Java

JEditorPane is able to display and edit different kinds of content. By default,
text/plain, text/html and text/rtf are recognized and passed on to the
EditorKit that is designed to handle it: DefaultEditorKit, HTMLEditorKit and
. In the following example, a URL can be given in a JTextField.
Clicking GO will invoke the setPage method on the JEditorPane that will load
the page into a default document and set the content type. Using the
mime type of the page, the pane will automatically detect the correct EditorPane to
Try: and

public class Main extends JFrame
   public static void main(String []args) {
      Main main = new Main();;
   public Main() {
      JButton uriButton = new JButton("Go!");
      // needs to be final to allow the inner class to access it!
      final JTextField uriTextField = new JTextField();
      final JEditorPane htmlPane = new JEditorPane();
      uriButton.addActionListener(new ActionListener() {
         public void actionPerformed(ActionEvent ae) {
            try {
               htmlPane.setPage(new URL(uriTextField.getText()));
            catch(Exception e) {
      getContentPane().setLayout(new BorderLayout());
      JPanel topPanel = new JPanel(new BorderLayout());
      topPanel.add(BorderLayout.CENTER, uriTextField);
      topPanel.add(BorderLayout.EAST, uriButton);
      getContentPane().add(BorderLayout.NORTH, topPanel);
      getContentPane().add(BorderLayout.CENTER, new JScrollPane(htmlPane));
      addWindowListener(new WindowAdapter() {
         public void windowClosing(WindowEvent e) {
      setSize(400, 400);
