I tried appending the root to the document as suggested:

  You can't use graphics2D.stream for this approach (it still doesn't
"know" about your document) you have to serialize the document you
construct "manually".  You can use batik.svggen.XmlWriter.writeXml, or
batik.dom.util.DOMUtilities.writeDocument to do this.

  There are some subtle differences which should be removed at some
point and only one should be preserved (patches welcome!).

and nothing got displayed. The code is in a simple servlet and I run it in
IE using the Adobe plug-in version 3.

The latest patch provided by Cameron works fine but if it's possible I'd
like to use the svggen.jar without custom modification and have the pi
included in the svg rendering. Any chance Cameron changes are going to be
commited to CVS?

Thanks

Hi all,

    This is a common misunderstanding The document you give
the SVGGraphics2D is not the document that is streamed it
is simply used as a factory for constructing the elements
of the independent document the SVGGraphics2D constructs
for it's self.

    So adding a PI to the document won't do any thing.
What you probably want to do is get the root of the
generated SVG tree and manually append that to the document
(with your PI).

this used to work. Any ideas what could be the cause?

In SVGGraphics2D.stream(Element, Writer, boolean) try changing the line

 svgDocument.appendChild(n);

to

 svgDocument.appendChild(svgRoot);
