Wireless Java : Developing with Java 2, Micro Edition

Despite Java's incredible popularity, the standard edition of Java is way too big and way too bulky to build wireless applications geared toward devices such as cell phones. Suds answer to this shortcoming is the release of Java 2 Micro Edition, or J2ME. J2ME has the potential to be as revolutionary in the wireless space as Java has been in the server space. This is the first book that gives real code for real J2ME applications, including extensive coverage of the new and exciting concept of "MIDlets". Wireless Java: Developing with Java 2, Micro Edition begins with a comprehensive foray into wireless Java programming with an overview of J2ME, the Mobile Information Device Profile (MIDP), MIDP applications (MIDlets), and a comparative discussion of the differences and similarities between the J2ME and Java Standard Edition APIs. These introductions set the stage for an ample investigation of the creation of both simple and advanced user interfaces, including demonstrations of how to manage the devices screen, interact with users through event handlers, create forms, and gather user data. An additional chapter demonstrates how MIDlets can communicate over the Internet using HTTP. The coverage of MIDP is completed with chapters on persistent storage and creating a gaming interface. Jonathan Knudsen concludes the book with three chapters devoted to advanced topics. The first describes techniques for overcoming the limited memory and processing power available on small devices. Next is an entire chapter devoted to parsing XML in a MIDP environment. Finally, you can read about how to make network connections secure by using cryptography. Wireless Java: Developing with Java 2, Micro Edition is the ultimate guide to sun's new wireless technology, J2ME.
