Summary: A must read if you want to learn about JXTA
Review: I learned many new things about JXTA reading this book. Overall, I would say that this is the best JXTA coverage I've seen in any book. So, if you're looking for a JXTA book I believe you'll be extremely pleased with this book.I'd been looking for a JXTA book for some time, but I didn't want a simple quick reference that left me wondering how to code for JXTA applications. I also didn't care to read through a API reference in order to understand what JXTA was all about. This book is something completely and impressively different. This is a great book for newcomers to JXTA, though I suspect anyone who's developed in Java will be able to follow along quite well. In fact, it's the author's writing style that makes learning JXTA almost effortless. The examples are numerous, easy to follow. The authors frequently tie the concepts together nicely and it's plain to see how the examples may be incorporated into larger applications. I like that approach. Another thing I especially appreciated was the author's effort to provide useful tips for solving real-world problems. I can hardly imagine buying another JXTA book because I believe I've found most, if not all, of what I need.

Summary: Avoid JXYA in a Nutshell!!!!!!!
Review: I strongly reccomend against this book. JXTA
is supposed to be a peer to peer platform, so
imagine my disappointment when I read the part
about how all computers running JXTA find
each other through some hard coded IP address.
Yes, computers running JXTA go there to get a
list of other computers running JXTA!
When I went to that address and
found only a handful of computers there, it was
obvious that nobody is taking JXTA
seriously. If you need any help with JXRA, then DON'T buyt htis book; look for another!!!!!!

Summary: not worth the time or your money
Review: I've just spent 5 hours reading this book hoping that I'd learn some new and innovative technology, but alas, all I got was a headache. At the core of jxta is something called the "resolver." The resolver is used by all jxta components to find advertised network resources such as a network pipe. Upon closer inspection, this key component implements its search using brute force network broadcast! Can you believe that the search is blasted out on all network interfaces and eventually reaches all jxta nodes! This technique was popularized by gnutella, but even gnutella, has improved upon its original design. Why would anybody want to use jxta (and its stupid search algorithm) instead of gnutella? Think this is bad? It gets worse! The other bonehead thing about jxta is that is relies completely on a centralized server called the rendezvous server. All nodes find each other through this bottleneck. This would be a problem if someone was actually using jxta! The book itself is disorganized, difficult to follow, and rambles along with no clear direction. I haven't read the other jxta books, but I did skim one in the store. If you would still like to learn about jxta, i'd recommend "Mastering Jxta."

Summary: Excellent book on JXTA
Review: Just read the book it is well organized and as a full
JXTA auctioning example. If you are looking for serious
JXTA programming that's the book you want to have.

Summary: The best book on JXTA available
Review: JXTA in a Nutshell contains lot of information into not a lot of space. It is the best book on the market for learning JXTA. It is worth reading, even if it is your first JXTA book. The book is fairly complete, with a full reference to the JXTA Java API and the JXTA protocols. There is a great deal of valuable information in the book, and it will serve quite well as a desktop reference.
The book is organized well, leading the user through the JXTA
core concepts. I particularly appreciate the way the book
has been orginized making it easier to find the specific information I want (discovery, pipe, peergroup, etc). In addition, I also liked the extra sections dealing with the
JXTA protocol specification to better understand JXTA.
In all, this book is the only JXTA book I need, but it will doubtless be one that I refer to repeatedly as I develop with the JXTA platform.

Summary: JXTA - save your money for something real
Review: Some pretty cool stuff like Java has come out of Sun in recent years, so I was expecting a lot from JXTA. The fact that this book was published by O'Reilly further raised my expectations. But, I was disappointed to find that JXTA is based upon the "resolver", a protocol that finds things using network broadcast storms. So, if you're like me and want to spend your time and money reading about something real, I suggest you pass on this one.

Summary: Excellent book!
Review: The book explains in very clear language almost every aspect of JXTA P2P programming and gives a good overview of all common JXTA concepts (Pipes, advertisements, discovery, peergroups). You'll learn how to design, implement, test and deploy your JXTA P2P programs. The book does a great job by identifying and providing solutions to common P2P pitfalls. I recommend this book to every programmer out there. If you are serious about writing JXTA programs this is the book to get.

Summary: good book
Review: this book describes the essential concepts of jxta clearly and concisely. the sample application (p2p auctioning system) is useful in learning to roll a p2p app. highly recommended despite the few insignificant typos.
