I bought the book Friday, started to read it that day (after work), continued the reading Saturday, and by Sunday evening I had ported almost the whole website for my workplace from Struts to Cocoon!The book transforms a very complex subject to a comprehensible level, to the point that you will be Cocooning just after a few days like an expert!My advice: GET THE BOOK!RCS
