Applet does not display

Hi guys this is my first post in the forum.

I'm just started to use the batik framework.
I'm writing an applet to show a svg file. I use eclipse as IDE to develop
the applet an it works. It show me the svg file.
When i tried to do the same on an html page using the applet tag, the applet
doesn't show at all.
I've added an display message on start of the applet and i see it but the
svg file isn't show.
Can anyone help me?

the Source of the applet is the following:

public class SVGViewer extends JApplet {

    JSVGCanvas svgCanvas;
    Document document;
    Window window;
    
	public void init()
	{
		String svgName;
		try
		{
			svgCanvas = new JSVGCanvas();
			getContentPane().add(svgCanvas);
			
			svgName = getParameter("svgName");
			
			// Parse the barChart.svg file into a Document.
	        String parser = XMLResourceDescriptor.getXMLParserClassName();
	        //SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
			URL url = new URL(getCodeBase(), svgName);
			svgCanvas.setURI(url.toString());
			
	        //document = f.createDocument(url.toString());
			setBackground(Color.ORANGE);
		}
		catch (Exception e) {
			// TODO: handle exception
		}
	}
	
	public void start()
	{
		JOptionPane.showMessageDialog(this, "STart");
		svgCanvas.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
		//svgCanvas.setDocument(document);
		//svgCanvas.setURI("a/846004349.image");
		try
		{
		svgCanvas.addSVGLoadEventDispatcherListener
        (new SVGLoadEventDispatcherAdapter() {
                public void svgLoadEventDispatchStarted
                    (SVGLoadEventDispatcherEvent e) {
                    // At this time the document is available...
                    document = svgCanvas.getSVGDocument();
                    Element root = document.getDocumentElement();
                    int w =
(int)Double.parseDouble(root.getAttribute("width"));
                    int h =
(int)Double.parseDouble(root.getAttribute("height"));
                    
                    setSize(w, h);
                    
                    // ...and the window object too.
                    window =
svgCanvas.getUpdateManager().getScriptingEnvironment().createWindow();
                    //window.alert("INIt");
                    // Registers the listeners on the document
                    // just before the SVGLoad event is dispatched.
                    registerListeners();
                    // It is time to pack the frame.
                }
            });
		}
		catch (Exception e) {
			// TODO: handle exception
		}
		//window =
