Promises, Promises (2/2 people found this helpful)

This book is a deception. It promises to get you up and running with J2ME bluetooth. However, it has a fundamental flaw in that it has requirements for hardware and software that are not specified on the cover or in the intro.

The chapter outline promises:
"The first complete example of a Java Bluetooth application is explained in chapter 5 ... we provide a short review of J2ME".

The example consists of a brief statement of functionality and some screenshots, i.e. a summary and a bit of HCI. Thereafter follows a listing with one comment and no main text explaining the code. Explanation! Explantion! Explanation!

Unless I worked for the company supplying the all-important (conveniently not mentioned on the cover or in the intro) toolkit I cannot imagine anyone being able to build, let alone get working, the first example.

The bluetooth software class needed is downloadable but gives poor instructions and refers to parts of the file system that I could not locate or determine how to create. This meant the classpath or class deployment could not be done with any confidence.

Because of the lack of transparency in this core software you even begin to doubt your understanding of Java as you try to retro fit its files and classpath settings to the poorly listed code!

This book is the metaphorical equivalent to Colonel Sanders telling you how easy it is to make KFC but only telling you that his secret recipe has salt and pepper in it - work out the rest yourself.

Apress even have the nerve to profile the technical editor of the book. What exactly did he do? Decide on the price tag?

I have paid £35 for the most demotivational text I have ever come across. I teach mobile commerce, J2ME and WML. This book almost made me give up on using j2ME in my teaching.

If there was a 0 star rating I would be using it - this book is a fraud that should be renamed blue-in-the-tooth for Java.

Excellent resource for the Bluetooth (12/12 people found this helpful)

Bluetooth is a short range (max range of 30-300 feet) wireless communications protocol. JSR-82 is a Bluetooth API for Java that allows Bluetooth enabled devices talk to each other using the Java programs. Using Bluetooth, a PDA could talk to a printer and ask for a document to be printed or two Bluetooth enabled PDAs could exchange Java objects. Even if you know nothing about Bluetooth or wireless communications, this book will give you enough information to get started.

The book starts with an examination of Bluetooth and the terminology you need to know to understand Bluetooth enabled devices. It then gets into the basics of the Bluetooth API for Java and developing programs using J2ME MIDP. Chapters cover creating a Bluetooth print server, passing objects between Bluetooth devices, and securing messages between devices. The authors discuss the PC software available to simulate two Bluetooth devices talking to each other so that you can develop an application without having two Bluetooth devices sitting on your desk. The final chapters covers topics such as Jini and Ericsson BlipNet. The book contains many well commented code samples demonstrating how to use the Bluetooth API.

The book is very clear and concise. The book reads as if it was written by a couple of enthusiastic Bluetooth developers anxious to share the technology. And they do an excellent job of doing exactly that. The book is well written and interesting. I started the book knowing almost nothing about Bluetooth but now I feel confident that I can develop Bluetooth applications. If you have any interest in Bluetooth then I can recommend this book as an excellent resource.
