Despite Java’s incredible popularity, the standard edition of Java is way too big and way too bulky to build wireless applications geared towards devices such as the Palm or cell phones. Sun’s answer to this shortcoming was the release of Java 2 Micros 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 uses the current version of J2ME to give real code for real applications, including extensive coverage of the new and exciting concept of "MIDlets". Wireless Java: Developing with Java 2, Micro Edition begins a comprehensive foray into wireless Java programming with an introduction of J2ME, the Mobile Information Device Profile (MIDP), MIDP applications (MIDlets), and a comparative discussion of the differences and similarities between the J2ME and JavaTM 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 device’s screen, interact with users through event handlers, and create forms and gather user data. An additional chapter explores MIDlet’s capabilities in interaction with the Internet over HTTP. 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 learn 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. About the Author Jonathan Knudsen is a Java developer and noted author of several books, including The Unofficial Guide to LEGO MINDSTORMS Robots, Learning Java, Java 2D Graphics and Java Cryptography. Jonathan began his object-oriented programming career in Objective-C on the NeXT OS, soon thereafter suffering through a couple purgatorial years in Microsoft's Visual C++ before graduating to Java in 1996. He has written extensively about Java and LEGO robots, including five books, a monthly online column called "Bite-Size Java," and articles for JavaWorld, EXE, NZZ Folio, and the O'Reilly Network. Jonathan holds a degree in mechanical engineering from Princeton University. |
