Product Description

With Nokia alone announcing deployment of 150 million phones running Sun's J2ME and Mobile Information Device Profile (MIDP), developer interest in these technologies is enormous. Now, there's an authoritative, example-rich technical resource that will enable every Java developer to build robust applications for any J2ME mobile device -- fast. Written by one of the world's most experienced Java developers and trainers, this hands-on book teaches J2ME and MIDP using more than 50 well-designed examples -- all of them clearly commented, thoroughly explained, and available for download on the Web. Core J2ME Technology covers everything a developer needs to get results. John Muchow begins with an overview of the J2ME, including configurations and profiles; then walks you through creating your complete J2ME development environment -- from downloading J2ME to troubleshooting. The book then provides exhaustive coverage of the MIDP programming interface: the basics of the MIDlet application lifecycle; event handling; low-level components; persistent storage; networking (including communication with servlets and session management); and more. The book also contains comprehensive references to both key elements of J2ME: MIDP and the Connected Limited Device Configuration (CLDC) specification. For all experienced Java developers who want to create mobile applications with J2ME.

5.0 out of 5 stars Great Introduction and reference, May 10, 2002

By	Steve Holmes (Sacramento, CA United States) - See all my reviews

I bought this book about two months ago when my company was starting a J2ME project. I read the first 6 chapters page for page as an introduction and then used the rest of the book as a reference. I now consider myself a proficient J2ME programmer.

I've used the book mostly as a reference and I have found that the way the chapters are laid out makes it very easy to find whatever information I'm looking for. The chapters on Record Stores are particularly useful.

One reviewer said to just read the online docs. CDLC and MIDP are not very difficult technologies to become proficient at but the documentation online will make it much harder on you. If you don't mind wasting hours of time to save [money] on this book thats fine. But if your time is valuable like mine break down and make the investment. This book and the JavaDocs will be all you need to start professional apps in J2ME.

4.0 out of 5 stars Start to Finish J2ME How to., February 8, 2002

By A Customer

Initially, What I liked regarding your book verses others was the big picture and the logical layout. You started with the basics - what is the history and the standard. Which was very well laid out, enough information to grab the facts. The second area I felt the book was broken into that all others seem to skip is the how to get started. Step by step, What do you need in software, What additions to the J2SE from Sun. What order do they get installed, What other nice stuff is out there to add (POSE, other emulators). This was well worth the cost of the book to me. I have around five or six "J2ME" books. All just assume this is self evident. If you want to spend a month reading all the standards, software notes, and history of the packages, it is. What I liked on your book was here it is - this is the current stuff and the order to load. This would have saved me several installation attempts of troubleshooting to discover another package is needed or the two I have are different versions. Last is the meat - the break down of the classes. What is or is not ported and some nice basic examples.
I like this approach and would consider it as mandatory to get J2ME up quickly and get a team moving on development in this area. If I went to the store and bought J2SE, CDLC, MIDP, and J2ME, Your book should be in the same package - It is the document that brings it together.

5.0 out of 5 stars Best Book for J2ME, May 8, 2002

By	chanakya - See all my reviews

This is the best book on j2me till date. It teaches core concepts in an easy to understand manner.Most books are rich in theory but Core j2me is rich in both Code and Theory.After reading this book you will be able to build you own j2me applications.As this is a book about core J2me it doesnt deal with developing enterprise application with j2me( like XML/security)but it provides you with the solid foundation on which you can build up.My advice is to buy this book if you are a new to j2me,learn the fundamentals and coding techniques from this book.then start reading other articles about xml/security to build enterprise application for j2me.Believe me After reading this book it wont take much time to understand other concepts of j2me.This is the must have book!!It explains everything with code examples.Though it would have been good if mr. Muchow have included shopping cart example in this book,which he demonstrates in his lectures.That would have made it a great book in core j2me aswell as j2me for enterprise application.
