Streaming SVG back to IE browser
Hi all,
Has anyone else seen these symptons?
I have a servlet that builds an SVG document using batik.
If I write the SVG out as a file, and use the IE browser to open the
file, the plugin works fine.
If I stream the SVG back to the browser(as the entire response), I get a
couple of plugin errors from IE5, (pop-up box with text "An error
occured inside a plugin contained on this page" and an OK button), and
the web server reports the following error:
[20/Jun/2001:10:32:51] failure ( 217): Internal error: exception thrown
from the servlet service function (uri=/Taipan):
org.apache.batik.svggen.SVGGraphics2DIOException: Connection reset by
peer, Stack: org.apache.batik.svggen.SVGGraphics2DIOException:

com.netscape.server.http.servlet.NSServletRunner.Service(NSServletRunner
.java:472)
I'm guessing when the plugin reports the error, it resets the
connection, refusing the remainder of the response.
>From Netscape 4.08 it appears to work fine.
Here is the code snippet:
ServletOutputStream out = res.getOutputStream(); // servlet
response
res.setContentType("image/svg+xml");
// Finally, stream out SVG to the standard output using UTF-8
// character to byte encoding
boolean useCSS = true; // we want to use CSS style attribute
Writer writeOut = new OutputStreamWriter(out, "UTF-8");
SVGGraphics2D svg2 = (SVGGraphics2D)(mg2);
svg2.stream(writeOut, useCSS);
Is this likely to be resolved by Adobe, or is it going to be an IE
plugin implementation problem?
How should I go about tracking this down?

Brigette,
Before streaming the file back to the browser, did you make sure to
set the http header's MIME type to be that of SVG? That might cause
a problem.

Denny,
There is a page on the Batik web site which documents the SVG Generator
module in Batik (the SVGGraphics2D class):
http://xml.apache.org/batik/svggen.html
Cheers,
Vincent.

Hi Everyone!
Any one know where I can find a java white board example that connects
to BATIK for SVG output?
Anyone have any interest in seeing such a thing put into place?
Cheers
Denny
