FOP/Batik problem with url(#id)

[La...@i2.com]

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 (listed at end of message) 
while it is trying to process the url.  If I remove all usages of 
url(#id), then everything works fine.

A reply from a post to the Batik mailing list offered a suggestion to use 
Batik 1.5 beta 4.  Is FOP 0.20.4 compatible with it?  If so, does anyone 
have a distribution I can use?  I tried to build a large jar file for 
Batik (by using the files from the 18 jars in the Batik distribution) that 
mimics the one shipped with the FOP distribution but now nothing works!

I haven't tried it myself, but can the FopServlet handle url(#id) ?  If 
so, then my JSP should work as well right?

TIA,
Larry Mason

No (interface changed).

It depends.

Try to set baseDir in the configuration, see
