Query: Nice book, but needs reviewing

The world of technology is changing with a very rapid pace. Okay, it's a common place, but i think that books should like the apps: to be updated every X months.This is the case of this book. I humbly think that this book is fabulous, but!! In some chapters lacks to be up to date. Security is explained without the new xml notations, who made me to rewrite when I reached a point where I didn't found solutions for the problems I had even on internet!! The wiring of the security isn't explained now as simple beans, but with the new xml notation that this book lacks.On the other side, it explains very well what is spring for and why you do need Spring. Sorry planet for not knowing until now. is very important and the first chapters are recommendable even for non programmers (deployers) in order to know what the hell is Spring and how to take advantage of it's capabilities.
