1 Mobile Computing MIDP Midlets are the java classes used (similar to applets) to establish java code executing on small mobile devices, such as mobile phones.\\Search for information on __CLDC, MIDP, J2ME__ to get information about this or check the {link:J2ME Device List|http://developers.sun.com/techtopics/mobility/device/device}. Sun's J2ME class library set is a reduced set from the J2SE and holds additional javax classes for the small devices. Suns's Java sites have plenty to start with http://java.sun.com/j2me . --I recommend using IMB DeviceDeveloper as IDE for developing (know as {link:WSDD|http://www-3.ibm.com/software/pervasive/products/wsdd/}) This is based on the [eclipse] platform as other IBM products. -- Since Nov04 I have switched to using the skd provided from Nokia supporting [eclipse] 2.1 and 3.0 and other IDEs, but my favourite is still [eclipse] and integration was pretty easy. For [Eclipse] 3.1/3,2 plugins for Sun's WTK and other SDKs such as Nokias are offered. There is also support for obfuscating (which I was missing, since size does matter). So see {link:EclipseME|http://www.eclipseme.org/} and {link:ProGuard|http://proguard.sourceforge.net/}. For building the final midelt, I tried antenna, but also had to face some issues (see [eclipseME and Antenna]). Development using MacOS is supported by {link:mpowerplayer|http://mpowerplayer.com/} and the WTK2.2. The WTK2.2 actually does not ship for MacOS, but I used the preverifier from mpowerplayer to get my build file working. During development time, it is recommended to use the {link:MicroEmulator|http://microemu.org}. See [MicroEmulator for MacOS j2me development]. 1 Midlets featured here - [WorkingTime] - Register Working hours to control time account - [ShoppingList] - Simple Shopping List (or ToDo List) - [MobileControl] - Basic suite to remote control pc applications via bluetooth mobile - [5ud0ku] - A [Sudoku] Game with Generator and Solver - [just1] - A [Hitori] Game - [k4kur0] - A [Kakuro] Game with Generator and Solver 1 Issues with J2ME development [Issues J2ME] 1 Midlets using Fullscreen Since MIDP 2.0 midlets supports the fullscreen mode. There is also a specific Nokia fullscreen implementation. Check out [FullscreenCanvasExample] to see how to build a midlet which supports fullscreen mode with just one single JAR which will run on MIDP 1.0 and MIDP 2.0 devices. 1 More Free midlets You will find some free midlets at http://midlet.org/index2.jsp 1 Information about mobile device performance http://www.club-java.com/TastePhone/J2ME/MIDP_Benchmark.jsp 1 Information about known issues http://www.j2mepolish.org/devices/issues.html 2008-01-27 21:01:32.014 2003-01-17 15:45:38.672
