FOP: Other Resources
I stumbled upon this excellent collection on XSLT, FO and other resources including Java (thanks to Rodolfo Raya of IBM - to visit his page click here )
Of course, I should thank Michael Morrison too, since he had mentioned about about apache.org in his book.
This website too has excellent tutorials on XSL-FO as well as other web technologies: http://www.learn-xsl-fo-tutorial.com/
