Book Description: 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.
An excellent book, April 26, 2002
Reviewer: Michael Pucciarelli from Darnestown, MD United States
This book is excellent. Great for a beginner. All the code makes sense. Easy to read. Very good appendix. Also, good for the experienced developer. Before buying this book, make sure you know JAVA 2 very well. I would recommend this book to anyone who wants to learn wireless JAVA.
Good for beginning to learn J2ME, April 17, 2002
Reviewer: MEHMET ENDER BATUR from Ankara, TURKIYE
This book may be taken as the introduction to start learning J2ME MIDlet programming. There are step-by-step instructions to download and install J2ME to the PC, and code, compile and run your first MIDlets. These are helpful for the beginner. On the other hand, make sure that you already know Java2. This is not a book for ground-up learning J2ME. The book is MIDP oriented, therefore do not expect much for CLDC coverage except a brief introduction. I have not managed to run all of the examples, even the 'originals' downloaded from the publisher's site. It was frustrating. You need to have a Palm device to test your MIDlets for Palm OS, because only 12 pages are spared for MIDP for Palm OS with no mention about the desktop PC emulator, but there are about 50 odd pages for J2ME APIs. You may take this book as the first step for J2ME without too much expectations, and be prepared to buy more books in order to master on the subject.
Excellent Focus on Distillation and Core Workflows, April 14, 2002
Reviewer: Roderick L. Barnes from San Antonio, TX
Mohmoud does an excellent job of distilling what is sine qua non to creating working midlets for various platforms. After explaining how to create J2ME programs using the command line he goes own to show how it can be done using contemporary graphical tools from Sun. You quickly reach the critical mass of being competent due to the author's good habit of presenting short lists of steps that lead toward program production.
One could wish that he spent more time discussing development for the Palm OS, JMS, RMI and XML. However, if the book continues to mature the way Oreilly books due, we can expect to see this and more in the next edition.
If you are looking to understand J2ME development and have on-hand quick-start help this book is for you. Chapters 3,7, and 8 quickly relate the important points and provide a helpful teaching context. It may not be enough for someone who has already begun the work of creating J2ME applications.
Easy to read and informative, February 12, 2002
Reviewer: J. Grondin from Santa Barbara U.S.A.
I am new to Wireless Java, but I have some practical knowledge of Java itself. The book provided me with super information on Wirless Java and how to develop MIDlets. The book is super easy to read and the examples are informative. The introduction to J2ME (chapter 1) is excellent: everything is put in context. The examples on MIDP networking are _excellent_. The MIDP4PlamOS chapter is pretty good -- I was able to install JavaHQ on my Palm device in no time. I converted some applications for the Palm and they are working great. I am loving this stuff. Thank you for an informative book. If you need a book to get started with Wireless Java get this one!
