circle on top of existing file?

["Georg A." <at...@eva.mpg.de>]

I am trying to draw a circle on top of a existing svg
  sample code below,
but it doesn't work, the map is rendered without the circle
what am i doing wrong?
thanks
Georg


#######sample code##########
try {
       String parser = XMLResourceDescriptor.getXMLParserClassName();
       SAXSVGDocumentFactory f = new SAXSVGDocumentFactory(parser);
       svgCanvas.setDocumentState(JSVGCanvas.ALWAYS_DYNAMIC);
     svgCanvas.addSVGLoadEventDispatcherListener
     (new SVGLoadEventDispatcherAdapter() {
       public void svgLoadEventDispatchStarted
       (SVGLoadEventDispatcherEvent e) {
       }
     });
       String uri = "file:" + new 
File("/0_Samples/worldcollapsed_jc.svg").getAbsolutePath();
       doc = f.createDocument(uri);
       svg = doc.getDocumentElement();
       circle = doc.createElementNS(uri, "rect");
       circle.setAttributeNS(null, "cx", "600");
       circle.setAttributeNS(null, "cy", "200");
       circle.setAttributeNS(null, "r", "100");
       circle.setAttributeNS(null, "style", "fill: red; stroke: blue; 
stroke-width: 10");
       svg.appendChild(circle);
	   svgCanvas.setSVGDocument((org.w3c.dom.svg.SVGDocument)doc);// 
invokes the rendering
	} catch (Exception ex) {
       // ...
     }

       String uri = "file:" + 
          new File("/0_Samples/worldcollapsed_jc.svg").getAbsolutePath();
       doc = f.createDocument(uri);
       svg = doc.getDocumentElement();

       circle = doc.createElementNS(uri, "rect");

       This line is all wrong.  First if you want a circle the
element name is... 'circle' not 'rect'.

        Second the NameSpace is the SVG Namespace not the URI of
the document(?) 

        Your code will likely work better with the following lines:

import org.apache.batik.util.SVGConstants;

      circle = doc.createElementNS(SVGConstants.SVG_NAMESPACE_URI, "circle");

       circle.setAttributeNS(null, "cx", "600");
       circle.setAttributeNS(null, "cy", "200");
