Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Only for begineers who don't want to do things right

By the time I got to chapter 4 I had almost given up on the book, it has a large number of mistakes, most of the code doesn't work as its presented. Luckily I have been doing struts for a couple of years and was able to get thru it.This may be an ok quick review but as far as best practices it isn't even close. As a matter of fact it does some things just plain wrong.
