(sorry if I'm wrong here, it's just a guess) , however since HttpUnit also serves to test
the overall application in addition to generating a list of compiled classes so I guess it's
better than using Jasper alone.

It completely bypasses jasper, because httpunit fetches the pages from 
the remote server. As long as hitting those pages doesnt have any side 
effects (shutting down the oil refinery, redirecting planes. etc), it 
gives you testing and jsp compiles in one go.

covers the basics - I'm in the middle of chapter 4 of the book, and it's been written very
well. I was able to understand the basics of Ant and write a build script all by myself, I'll
take a look at "Ant in Action" soon.

ok, you need to fast forward to chapter 12, and ignore the bit where it 
tells you how to use <jspc>.  that bit has been cut from the sequel for 
that very reason.
