All,
I recognize that this may be an elementary question but I'm stuck with what
I know is a Classpath problem and I can't figure out how to fix it. I'm
trying to learn ant and I have some tutorials but they won't build. The
error says:

So what in there is the missing element and what do I need to get in the
Classpath? Many thanks.
