Subject: possible to append to system classpath?

Given a fileset pattern, is it possible to append a collection of *.jar
files to my system classpath for the duration of a build.xml execution?
This makes building extremeley portable after copying out files from a
source tree.

I'm fed up of getting the following error message when trying to run my
custom task, where the necessary  jar file is in a known destination (and
not in the system classpath).

I've tried dynamic class loading, which loaded, but then got instanciation
errors.   I can't run it on the command line using CommandLine as the class
cannot be found.

Is it preferable to have the necessary jars in the classpath instead of
dynamic class loading?
