Well - I've managed to work through most of the previous problems I was
having. I dropped the idea of doing the SVG transcoding output in JSP in
favor of a graphing servlet.
Here is my current problem:
org.apache.batik.transcoder.TranscoderException: The specified XML document
fragment is not an SVG document
I've managed to search through the mailing list archives and I did catch a
thread with someone having a similar problem. But, they weren't running a
document through a parser first though.
I've found that I can open an SVG file and transcode it sending it the
InputStream of the file. It reads it and works great! (found a great SVG
program from www.jasc.com called WebDraw that outputs SVG) I can take my
file straight out of WebDraw and transcode it to a jpeg.
The problem comes in when I parse the document with Xerces first, then send
the document to transcode instead of the file stream. It keeps telling me
it's not an SVG document. So, I had Xerces parse the document, then output
the XML file after the parse - and I saved this out to a test.svg file. I
then passed the stream of that file into transcode and it worked fine!
Why can I output the parsed XML data from Xerces into a text file and
transcode that, but I can't transcode by sending the document directly?
Without being able to parse the file on the fly, I can't modify the
rectangle attributes to dynamically change my bar charts (unless I do
something crazy like parse the file, make the changes, save it out to a text
file, then open and transcode that).
Thanks,
- Brent
