Editorial Reviews:
To the experienced Java developer, J2ME (the Java 2 Micro Edition) looks just familiar enough to be tempting, but just different enough to warrant caution. J2ME in a Nutshell provides the extra security you need when venturing into programming for cell phones, PDAs and other consumer electronic devices. It gives you the reference material you need for J2ME, together with a tutorial that leverages your existing knowledge and teaches you what is different about J2ME without boring you to tears with details you already know. J2ME in a Nutshell provides a solid, no-nonsense reference to the "alphabet soup" of micro edition programming, covering the CLDC, CDC, KVM and MIDP APIs. The book also includes tutorials for the CLDC, KVM, MIDP and MIDlets, MIDlet user interfaces, networking and storage, and advice on programming small handhelds. Combined with O?Reilly's classic quick reference to all the core micro-edition APIs, this is the one book that will take you from curiosity to code with no frustrating frills in between.
Designed for writing programs that need to fit into embedded systems and other small environments, Java 2 Micro Edition (J2ME) has minimal resource requirements. J2ME in a Nutshell explains the J2ME way of doing things with a particularly handy mix of API documentation and example-centric tutorials. Kim Topley--who's written a couple of highly regarded books for Prentice-Hall's Java series--uses the proven Nutshell format to explain J2ME concisely but thoroughly. For the sorts of people who will be writing embedded applications in Java--programmers with experience either in other Java environments or with other embedded systems environments--this is a very good way of conveying information. You can read this book, like all Nutshell books, from front to back in an effort to become familiar with its eponymous technology. More often, though, you'll search for a particular aspect of J2ME (particular graphical user interface elements, say, or over-the-air provisioning of MIDlet suites) and read Topley's prose explanations and annotated example code. These treatments are frequently enough to help you overcome stumbling blocks you encounter in the development process. If you're just looking for a reminder of how various classes work (their properties and methods, their return types, and their relationships to other pieces of J2ME), turn to the comprehensive J2ME API reference. Helpfully, it's not dry documentation: Topley comments on how to use each. --David Wall Topics covered: Java 2 Micro Edition (J2ME) generally, and classes within it specifically. In addition to an annotated API reference, this book holds a lot of information about graphical user interfaces (GUIs) for small devices, the special considerations of designing applications for wireless environments, the Mobile Information Device Profile (MIDP) and MIDlets.

 In a nutshell?
This book reads like a white paper on j2me... not very in depth or up to date. Not a very good effort from Oreilly, which is surprising.  Needs a second edition ...
This book does not cover MIDP 2.0, only MIDP 1.0. This makes it uninteresting to buy it. Are the authors considering a 2nd edition?
Still the book follows the classic nutshell O'Reilly style and is useful as a desktop quick reference.
A good aspect also is that unlike other books, it covers some CDC-based PDA programming. for the novice
The information in the book was meant for the beginner. Half the page is filled with reference to classes & packages which are available free on the web on java.sun.com
Dont understand the need to be paying for free information.
The author seems did not have enough material or information to fill the book. A slightly better book is "Java on PDAs: Developing Applications for PocketPC and Palm Devices" by Daryl Wilding-Mcbride.  More of a reference
The reader from Columbia, SC, said it right: this book is a reference, not a place to learn J2ME. Like the other books in O'Reilly's "In a Nutshell" family, the book has two parts: a quick rundown on the features of J2ME, and a reference part on all the details of the language. The book's audience is someone who already knows something about the J2ME platform, such as how it looks, how it runs on a PC, and how it produces the code you can upload to a device. If you want to see a tutorial type of book on J2ME, you won't find it here. Since I never learned Java completely, I find it difficult to follow the book. If you already know Java well, you may find the book easier to follow, although again you won't find detailed, step-by-step sample programs.In short, probably great for someone already programming in J2ME; not helpful for someone wishing to learn J2ME. Need to improve....
Should improve description with short
and clear language. In a lot of places,
the text is wordy and does not get the point across. More Customer Reviews:
