How to update Apache FOP in eXist-db?

Aside my question about commercial processors, I would like to test the newest version of Apache FOP. However, I met problems whilst trying to do that according to this article.

There are some parts which are different in the last dev versions of eXist but the overall idea should work, I think.

I had:

# XSL FO transformations (Uses Apache FOP)
include.module.xslfo = true
include.module.xslfo.url = http://apache.cs.uu.nl/xmlgraphics/fop/binaries/fop-1.1-bin.zip

Changed to:

# XSL FO transformations (Uses Apache FOP)
include.module.xslfo = true
include.module.xslfo.url = http://apache.cs.uu.nl/xmlgraphics/fop/binaries/fop-2.1-bin.zip

I removed the old fop.jar file from $EXIST_HOME/extensions/modules/libs/.

After these steps I ran build.sh. Strange thing was it did not seem to download the new package (I was not able to track that in the log of the build.sh process. However, in the $EXIST_HOME/extensions/modules/libs/ there was new fop.jar present (not sure of what version).

As for $EXIST_HOME/extensions/modules/build.xml, this is what differs most from the original article I mentioned. There is no specific information about the version of FOP used.

After starting the app and trying to produce a pdf, I got this error from Jetty:

HTTP ERROR 500

What am I missing? I would expect fop.jar figures there as a library only and build.sh could fix everything else, if necessary.

the upcoming v3.0 release supports FOP2.1 ; this should work OK, though a few issues are reported.

Note that Apache changed the directory structure for FOP a bit, you might want to verify the new location....
