Overview
Learning Wireless Java is for Java developers who want to quickly come up to speed and create applications for the Micro Edition audience. This book covers the Connected, Limited Device Configuration and the Mobile Information Device Profile (MIDP), both currently available from Javasoft. The CLDC contains APIs for small devices that are constrained by both memory and processing power. MIDP builds on top of the CLDC and adds APIs specifically for devices such as mobile phones and pagers, allowing programmers to create MIDlet applications.
This book offers a solid introduction to J2ME and MIDP, including an explanation of the J2ME Wireless Toolkit, the MIDlet lifecycle methods, the Java application manager, and the CLDC and MIDP constraints. In addition, we cover the javax.microedition.io, javax.microedition.rms, javax.microedition.lcdui, and javax.microedition.midlet classes, as well as the modified java.lang, java.io, and java.util classes. Discussion centers around building safe, compact applications with the sophisticated graphical interface, database, and networking capabilities that the J2ME supports. In addition, this book also shows you how to download your applications to the latest J2ME-enabled devices, including the Motorola i50x and i85s phones and upgraded Palm handhelds.
A solid introduction to working with the Mobile Information Device Profile (MIDP), which contains the APIs designed specifically for writing applications that need to run on wireless and embedded devices. It includes reference material on the core and javax.microedition classes, as well as on the classes specific to the various wireless platforms the J2ME supports.

Editorials
From Barnes & Noble
The Barnes & Noble ReviewQuietly, Java Virtual Machines have found their way into an enormous number of wireless devices. Using Java 2 Micro Edition, it's now possible to build some extremely powerful and flexible enterprise applications. It's just a matter of time -- and now's the time to prepare. If you want to leverage your hard-won Java skills in tomorrow's wireless environments, here's the book to get you started.
Learning Wireless Java assumes you know your way around Java but assumes no wireless programming experience. Qusay Mahmoud starts with an overview of the J2ME platform and Sun's "Honey, I Shrunk the JVM and APIs" approach to wireless development. He presents in-depth explanations of the key elements of the J2ME application runtime environment: the Connected Limited Device Configuration (CLDC), Sun's stripped-down KVM virtual machine, and the Mobile Information Device Profile (MIDP) APIs, which provide for user interfaces, persistence, networking, storage, and other essential features of wireless applications.
You'll start writing code quickly, then master each key aspect of MIDlet programming. There's a full chapter on wireless user interface development (and why you can't just use your AWT or Swing classes); detailed coverage of screen navigation and event handling; and example-rich coverage of J2ME networking (including security). The book ends with a closer look at J2ME on the Palm OS wireless platform and a quick API reference to four javax.microedition packages you'll be working with constantly. (Bill Camarda)
