Re: AbstractMethodError when trying to extend FOP
Turn on debug info in the build.xml and recompile FOP. Having line
numbers will make it a lot easier for you to track down the problem.
Looking at the source of Driver I guess you don't have a method
addToBuilder(FOTreeBuilder) in your ElementMapping implementation.

AbstractMethodError means that a method on a class is called that is
abstract. Compare your implementation with
org.apache.fop.svg.SVGElementMapping. addToBuilder is just plain public
and that's how it should be. Going to bed now...back in 9 hours.
