The J2ME Wireless Toolkit is a set of tools that makes it possible to create applications for mobile phones and other wireless devices. Although it is based on the Mobile Information Device Profile (MIDP) 2.0, the J2ME Wireless Toolkit also supports a handful of optional packages, making it a widely capable development toolkit. 1.1 Quick Start If you’d like to get started right away, try the demonstration applications that are included with the J2ME Wireless Toolkit. To run the demonstrations, start KToolbar. On Windows you’ll do this by choosing Start > Programs > J2ME Wireless Toolkit 2.2 > KToolbar.1 You’ll see a window like this: 1. Depending on how Windows is configured, you might need to choose Start > All Programs instead of Start > Programs. FIGURE 1 The KToolbar window Next, click on the Open Project... button to open a demonstration application. You'll see a list of all the available applications. Pick one of them and click on the Open Project button in the dialog. Once the application is open, all you need to do is press the Run button. The emulator will pop up running the example application. Most demonstrations are self-explanatory, but some have additional instructions. See Appendix A, “Application Demonstrations,” for additional details. All the source code for the demonstration applications is available in the {toolkit}\apps directory. Each demonstration has its own project directory. Inside the project directory, the source files are in the src directory. For example, the source code for the games demonstration is in {toolkit}\apps\games\src directory. 1.2 The Tools in the Toolkit The J2ME Wireless Toolkit has three main components: ¦ KToolbar automates many of the tasks involved in creating MIDP applications. ¦ The emulator is a simulated mobile phone. It is useful for testing MIDP applications. ¦ A collection of utilities provides other useful functionality, including a text messaging console and cryptographic utilities. J2ME Wireless Toolkit User’s Guide • October 2004 KToolbar is the center of the toolkit. You can use it to build applications, launch the emulator, and start the utilities. Alternately, the emulator and utilities can be run by themselves, which is useful in many situations. If you want to demonstrate MIDP applications, for example, it...
