Subject FOP/Batik problem with url(#id)
Date Mon, 14 Oct 2002 18:46:00 GMT
I'm using FOP 0.20.4 to transform SVG into PDF from a jsp page (wrote my 
own JSP tag to invoke FOP).  The content uses url(#id) in various places 
(example below).
<svg:pattern id="sbBgPatt" preserveAspectRatio="xMidYMid meet" width="2" 
height="2" patternUnits="userSpaceOnUse" shape-rendering="optimizeSpeed">
<svg:rect x="0" y="0" width="2" height="2" fill="white"/>
<svg:rect x="0" y="0" width="1" height="1" fill="rgb(102,204,255)"/>
<svg:rect x="1" y="1" width="1" height="1" fill="rgb(102,204,255)"/>
</svg:pattern>
<svg:rect fill="url(#sbBgPatt)" height="16" width="716" x="105" y="532"/>

If I execute FOP from a command line, no errors occur.  However from 
within my JSP environment, I get an exception while it is trying to 
process the url.  If I remove all usages of url(#id), then everything 
works fine.

My question is as follows - Is url(#id) supported at this time and if not, 
is there another syntax that is working?  I believe FOP 0.20.4 ships with 
Batik 1.5beta2.
