Hi,
I had a bit of trouble getting the base URL setting to work, but I have done
something similar to resolve the problem of relative/absolute paths.
In my servlet I used Thomas' suggestion of retrieving the URL of the
servlet. The code below will do this (may need modification depending on the
request that came into the servlet):
String file = request.getRequestURI();
file = file.substring(0,file.lastIndexOf('/')+1);
URL reconstructedURL = new URL(request.getScheme(),
request.getServerName(),
request.getServerPort(),
file);
This will return you something like "http://hostname:123/contextname/";.
I then pass this "baseUrl" to my class which generates the SVG doc and set
my stylesheet location like this (so now we have an absolute path and the
JPG Transcoder classes work fine).
ProcessingInstruction pi =
doc.createProcessingInstruction("xml-stylesheet", "type=\"text/css\"
href=\"" + baseUrl.toString()+"resources/styles/style.css" + "\"" );
doc.insertBefore(pi, doc.getDocumentElement());
Thanks for all your help with this,
Regards,
Dylan.

Hi Dylan, Tonny,
To extend on Tonny's answer a little. In Batik all references are
resolved relative to the
Document's base URL (Document.getURL). The problem you have is that when
you
build the document 'in memory' it doesn't have any base URL. There are
two main
ways to 'fix' this. First is to give the Document a base url by calling:
batik.dom.svg.SVGOMDocument.setURLObject
This is a Batik specific method for providing the Document's base url.
You can also
set the 'xml:base' attribute on the root SVG element, which is a standard.
Then the
questions becomes what to set it too.
I think you can get the URL of the servlet which would probably be a
good choice.
