I wrote an Ant task that needs to load some files ...
and I've tried getting at it with (and more) from within my task's code:
i had a bunch of trouble getting resources from jars a while back,
but was all in java. if you are getting a null when trying to get the
resource from plain old java, then the code below may be of interest.
i had resources with the same name in different packages, with
data/test files in src/ and tst/. also, iirc, there were lot's
problems with file names in windoze. i can send you the zip of the
project if you like.
thanks
