Query: Don't waste your time

I bought this book hoping for a quick jumpstart to getting a simple xdoclet/struts app up and running.The example code from the "Building Struts Apps with Ant and XDoclet" is so bad, it's a disgrace. I spent more time figuring out why their code wasn't even close to working, than I would have if I had just skipped their book altogether. It couldn't work, it never worked, and it shouldn't have been published.
