Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Sorely Lacking

I am very dissapointed in this book, as I purchased it thinking it would give real techniques for using struts. Instead it's just like so many other technical books out there where they give top-soil kind of overviews of the technology. It may be for getting basic concepts of struts, but whenever I find myself trying to lookup up real-world solutions there are no answers.
