Subject RE: Write a svg document to a file

>From your original post, it looks like you're using the SVGGraphics2D to create document
fragments.  That approach doesn't work well in that the SVGGraphics2D object doesn't render
anything to your document.  I ran into that problem myself.  You did say you appended everything
to your SVG root element though.  The empty file does sound problematic of using the SVGGraphics2D
object and expecting to have elements in your document that may not be there.  How are you
adding things?  You may want to look up a quick routine to print DOM documents to the screen
so you can see what the DOM tree actually represents.

Subject: RE: Write a svg document to a file

Thanks for your answer. I tried your suggestion : I wrote :
org.apache.batik.dom.util.DOMUtilities.writeDocument(doc, new FileWriter("c:\\test.svg"));
where doc is the Document described in the example below.
But it doesn't work : the svg file created is empty. Do you know why ?
As I created the svg document by appending everything to the svgRoot element, I also tried
as follow : 
org.apache.batik.dom.util.DOMUtilities.writeDocument(svgRoot.getOwnerDocument(), new FileWriter("c:\\test.svg"));
but it failed too.
Do you know what to do ?
Thanks again.

	Subject: Write a svg document to a file
	I use Batik to create a svg document and display it on a window. For that I use the above
code :
	public ActionForward doPerform(ActionMapping mapping, ActionForm form, HttpServletRequest
request, HttpServletResponse response) throws Exception {
	/*creation of the svg document */
	DOMImplementation impl = SVGDOMImplementation.getDOMImplementation();
	String svgNS = SVGDOMImplementation.SVG_NAMESPACE_URI;
	Document doc = impl.createDocument(svgNS, "svg", null);
	SVGGraphics2D svgGenerator = ne w SVGGraphics2D(doc);
	Element svgRoot = svgGenerator.getRoot();
	/*insert svg into the document*/
	/*send to output*/
	java.io.OutputStream out = response.getOutputStream();
	boolean useCSS = false;
	Writer wout = new OutputStreamWriter(out, "iso-8859-1");
	svgGenerator.stream(svgRoot, wout);
	This works fine. My problem is to send the "svgRoot" to a file on the server. Here is my
code : 
	BufferedWriter bw = new BufferedWriter(new FileWriter("c:\\test.svg"));
	svgGenerator.stream(svgRoot, bw);
	The document test.svg is created but when I try to open it I have an error : the first line
is : 
	"" instead of "" and I'm not able to open the file.
	What should I do ?
	Thanks in advance.
