Query: Great book

This is a great book. I used it to teach myself HTTPUnit even with little Java knowledge. The chapters on the API are my main source now for my work. They include code snippets to get you on your way to doing useful things with HTTPUnit and the other APIs. Mr Hightower also hangs out on the mailing lists for some of these APIs and is extremely knowledgable on the subject.
