Hi, Currently Batik is listed hardcoded in all the service-files under META-INF/services inside fop.jar. You can remove support for SVG by removing these entries (you need to change the files inside the jar), then all the Batik/XML related jars are not necessary any more and can be omitted.
After this we now use fop successfully with only the following jars: Avalon-framework commons-io commons-logging fop xmlgraphics-common Thanks...

(You can build these jars with the target "jars" of Batik's Ant build). Also, I think that FOP 1.0 uses xmlgraphics-commons 1.4 (instead of 1.3.1).
