A must have book for all levels of Camel users,
This review is from: Camel in Action (Paperback)
I performed a technical review on the book, and the first thing I did was open the source code and run through the examples. Each of the examples was well documented, thorough and all had unit tests.
Combine this with very detailed history, theory and practical application of the Camel framework, you end up with a book that will kick start you on a Camel project, as well as be an invaluable reference resource for solving even advanced problem spaces.
