Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Not for those new to Java; maybe of little use to anyone.

Besides having numerous errors in the examples, the book has three nasty characteristics: it consists almost solely of small code fragments and commentary; it routinely makes forward references to topics later in the book; and, it uses Struts 1.0 examples to start and makes an annoying (yet incomplete) transition to Struts 1.1. For one just starting to work with Java technologies I found use of the book detrimental to learning Struts. (I had been told it was not a bad reference.) I would have given it a lower rating had the review interface allowed it.
