How can I display an HTML file as a web page?

Question

My code reads an HTML file and I want to show it in new frame as a web page. But I don't know - how can I do this?

This is my code:

public class EditorPaneLoad extends JFrame{ 

public EditorPaneLoad() throws Exception{

    FileReader reader = new FileReader("a.html");
    JEditorPane editor = new JEditorPane();
    JTextPane editor = new JTextPane();
    editor.setContentType( "text/html" );
    editor.setEditable( false );
    editor.read(reader, null);
    //System.out.println(editor.getText());
    //System.out.println("\n------------\n");
    Document doc = editor.getDocument();
    // System.out.println(doc.getText(0, doc.getLength()));
    JScrollPane scrollPane = new JScrollPane( editor );
    scrollPane.setPreferredSize( new Dimension(300, 200) );
    getContentPane().add( scrollPane );
}

public static void main(String[] args)
    throws Exception
{
    EditorPaneLoad frame = new EditorPaneLoad();
    frame.setDefaultCloseOperation( EXIT_ON_CLOSE );
    frame.pack();
    frame.setLocationRelativeTo( null );
    frame.setVisible(true);
}
}

Answer 1

// opens "a.html" in the default browser..
Desktop.getDesktop().open(new File("a.html"));

See Desktop.open(File) for details.

Answer 2

If I get it right, you want to render HTML through a desktop window of your application.

Perhaps flying saucer would help you. An alternative, Lobo would be rendered using javafx but it would only support HTML 4.

Hope I helped!
