J2ME refers to a diverse number of technologies based on the java platform.

Many "J2ME" books focus solely on MIDP/CLDC, which is currently the only widely available profile/configuration of J2ME. Thus, you get books that tend to get repetitive in terms of their content, especially those books that focus on the "basics".

Fortunately, this book does NOT confine itself to the basics. It not only explores the history of J2ME (a MUST for any serious developer), but it also deals exhaustively with issues regarding real world design and implementation of enterprise systems (a NECESSITY for developers wanting to do more than just games for MIDP). The book also delves into using J2ME in PDAs using kjava (the new PDA Profile, or PDAP, was not finalized yet at the time this book was published), and gives a good summary of other java technologies and how they relate to J2ME.

This is a good book for both beginners and upper mid-level J2ME developers.

This is a good book for programmers new to J2ME development. It is assumed that you have experience in Java programming. The authors illustrate the J2ME history and how the Micro Edition fits in the Java family. After explaining the common J2ME architecture, they show how the profiles support the different devices that run J2ME. The common architecture with different profiles allows programs to be easily ported to different devices. Subsequent chapters concentrates on the MIDP/CLDC (small device, cell phone/PDA) profiles and other profiles are not discussed much after the first couple of chapters.

The book is very well organized. The book goes through example of how to built a MIDP application for cellular phones. The tutorial chapters go through everything from setting up the development environment, to coding, and running the application. The explanations are complete and do not leave anything out. The example gives a solid foundation of how to write J2ME applications. After reading these chapters, you should have a through understanding of J2ME.

This book is not a reference, but a tutorial by example and it's extremely useful for its extensive explanation, as well as a source for all kinds of examples. I would recommend the book to any beginner J2ME programmer, but because of the rapid changes in J2ME the book would not be comprehensive for future J2ME API's.

El libro mas completo que he visto de J2ME, el único inconveniente es que esta un poco desactualizado.
Espero que saquen versiones recientes.
