Wireless Java Programming with Java 2 Micro Edition (Sams white book) Book

Perfect for the experienced Java programmer making the transition to wireless development, Wireless Java Programming with J2ME delivers a capable tutorial about what's new and different on smaller Java devices. This title is all you need to get started writing wireless applications successfully.This book provides a nicely packaged tutorial for wireless development beginning with a tour of the acronym-laden world of Java wireless devices based on the Java 2 Micro Edition (J2ME). You'll learn about the Mobile Information Device Profile (MIDP), which this text centres on, plus the Connected Limited Device Configuration (CLDC). Clearly, this is a market in flux, and the authors do a good job of describing the kinds of J2ME devices available today. They also explain what's different about J2ME development when compared to traditional Java 2 programming.After this introduction, the book delves into the APIs you'll need to master to use J2ME. The authors create a number of "MIDlets" for wireless devices (such as a PIM and eventually a front-end for an online bookstore). They cover the new APIs that are used to program such devices. This includes the higher-level UI library for MIDP devices, which lets developers design for the restricted displays of these devices. They also cover lower-level graphics, which calls for a more do-it-yourself approach to UI design. Illustrated with a calendar utility, they show you how to draw on the screen of a wireless device.Later sections look at other features that you need to create robust wireless applications in Java, including network connectivity options (like sockets and HTTP), plus storing records in the built-in storage APIs that come built-in on the platform. The book also covers the surprising variety of XML tools that let you add XML support to wireless applications. The centrepiece of this text is the authors' MotoShop--a case study for a wireless front-end for an online bookstore, which is used to demonstrate many of the techniques covered earlier in the text. Final sections on SyncML (for synchronising data between wireless devices) and new support for Java on the popular DoCoMo i-Mode platform help round out this book.With the wireless marketplace poised for explosive growth, this title can let Java developers get ready for a new kind of Java platform. This book delivers a very solid tour of what an intermediate to advanced programmer needs to get started building the next generation of wireless software in Java. --Richard DraganRead More
