Great stuff Thomas, using the file:/// prefix has got it working. I know I'll need to revisit this when I deploy everything in an EAR, but is great to have it working as is.

"C:\svg\style.css" is a relative URL, you need to make it absolute. When the browser renders the file it provides the base url of the document (which is likely a 'file:' URL) which is used to turn the relative URL into an absolute URL. I suspect all you need to do is use: "file:///C:/svg/style.css" Typically I will use the JDK provided functionality new File("C:\svg\style.css").toURL() Which almost always gives the 'expected' behavior for files... > Thanks in advance again for any help, > > Regards, > Dylan. > > > -----Original Message----- > From: [EMAIL PROTECTED] [mailto:[EMAIL PROTECTED] > Sent: 11 April 2006 14:13 > To: [email protected] > Cc: [email protected] > Subject: RE: CSS ignored when exporting to JPG > > Hi Dylan, > > "Dylan Browne" <[EMAIL PROTECTED]> wrote on 04/11/2006 07:12:20 > AM: > > > So Im guessing the stylesheet is not being found now? > > org.w3c.dom.DOMException: Null Document reference: Invalid CSS document. > > Correct, most likely Batik can't find your CSS style sheet.
