There's a bug on that page: ${antHome} should be ${ant.home}. But
it's not necessary to specify ant-trax.jar in the classpath anyway.

This is exactly what was causing my problem. Turns out xalan-j was
already on my CLASSPATH environment variable, so Ant was always
finding it first, no matter what I specified in the classpath
attribute of Xslt. Ugh...classpath hell...
Unfortunately, it's not so easy to fix this because I use Fink, and
its ant-optional package, which is required for any of Ant's optional
tasks, depends on xalan-j.

Okay, that should fix my Fink problem, except I can't get it to work.
I've created a test case that's just like the Ant Wiki code, except
I've specified net.sf.saxon.TransformerFactoryImpl in the <factory>
element. But when I do that, I always get
java.lang.ClassNotFoundException. I can work around it by explicitly
putting Saxon's JAR in the -lib command-line parameter, or in my
CLASSPATH environment variable, but then that defeats the whole point
of a factory override.
Here's the test case:

How do I get the override behavior you describe, instead of a
ClassNotFoundException? I'm using Ant 1.7.0. Thanks,
Trevor
