Learning Wireless Java
Help for New J2ME Developers
Publisher: O'Reilly Media
Final Release Date: January 2002
Pages: 266

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 good jumpstart.

Comments about oreilly Learning Wireless Java:

Certainly not definitive, but about what I'd expect in 150 pages. I feel the objective was to bring the reader up to a level where the API javadocs had some meaning and context. I feel it does this quite well.

Step 1) Read the book.

Step 2) Read the API Javadocs.

Step 3) Have fun!

Learning Wireless Java Review

Comments about oreilly Learning Wireless Java:

This book reads as if the author just finished reading a book written by SOMEONE ELSE on the same topic. Everything is scatchy. The examples are so trivial that you can find them on the web (free of charge!) There are also countless and obivious erros all over the places which makes me think the author may never actually tried programs on the device himself. overall a rush job to make quick money.

Learning Wireless Java Review

Comments about oreilly Learning Wireless Java:

Hi,

I tried the sample on my local machine. It doesn't work properly. It only works at the first time when I invoke the today.jsp. After that, I have to restart my jrun server in order to invoke the today.jsp again.

I don't know what is going on.

If anyone has ideas, just let me know it.

Thanks in advanced

Eddy
