Re: Javac Run By Ant Script is Unable to Find External Jars

I apologize for being a pest but this is a problem I cannot resolve on
my own. The more I read the more confusing it gets. It seems like there
are thousands of ways to accomplish what I want but none make any more
sense than what I have. Is there no one that can help me debug this
problem or at least point me in the right direction?
