Implementing text comonent content scaling

Question

Hi, I need to implement the HTML view (text fonts, images...) scaling. So how to do it? I havn't found JEditorPane is able do this and tried to run a simple test before. This code doesn't work: html_document and view are valid (non null) but the view.paint(g,r) call throws the NullPointerException. What should I get know in depth before? Could the view painted well, I tune the AffineTransform accordingly...
    class TextArea extends JPanel {
        HTMLEditorKit editor_kit;
        HTMLDocument html_document;
        ViewFactory view_factory;
        View view;
        public TextArea() {
            try {
                editor_kit=new HTMLEditorKit();
                view_factory=editor_kit.getViewFactory();
                html_document=(HTMLDocument )editor_kit.createDefaultDocument();
                URL doc_url=new URL("http://c22/j2sdk-1_4_2-doc/docs/index.html");
                InputStream stream=doc_url.openStream();
                editor_kit.read(stream,html_document,0);
                view=view_factory.create(html_document.getDefaultRootElement());
            catch (Exception e) {
                e.printStackTrace();
        protected void paintComponent(Graphics g) {
                try {
                    Dimension size=getSize();
                    Rectangle r=new Rectangle(0,0,size.width,size.height);
                    view.setSize((float )size.getWidth(),(float )size.getHeight());
                    view.paint(g,r);
                    return;               
                catch (Exception e) {
                    e.printStackTrace();
    }
