Instruct: Classify Amazon reviews into positive or negative sentiment
Query: Amateurish and badly edited

I agree with all the negative reviews already posted, but I was so frustrated with this book I had to add another voice of criticism.The book was obviously a manuscript dump with no editing that I could detect. Why Wiley thinks they can charge this amount for no work at all is beyond me. It is littered with grammatical errors, incomprehensible sentences, and annoying repetition. In short, it is nearly unreadable. To add insult to injury, there are countless summaries which condescend to tell the reader that she should now have a good understanding of the covered material, and can move on. Don't be so sure you will have a good understanding. I did not, and I've been using RMI for some time.As others have stated, the examples are contrived, and not very well written. There is very little here of use for those developing large-scale distributed systems.Save your money (considerable money, in this case) and stick to Sun's website.
