Device Property Files

The device property files consist of a set of files that define the device’s behavior and appearance. Each set of device property files is located in a directory whose name determines the name of the device.

{j2mewtk.dir} is used to refer to the directory in which the J2ME Wireless Toolkit is installed. For example, if you installed the J2ME Wireless Toolkit in the default directory C:\WTK21 then {j2mewtk.dir}\wtklib represents C:\WTK21\wtklib.

The device property directory must be located in {j2mewtk.dir}\wtklib\devices so that it can be used by the J2ME Wireless Toolkit.

For example, TABLE 1 lists the device property file for a device named DefaultGrayPhone and the shared property files used by all the devices provided with the Wireless Toolkit. The DefaultGrayPhone device property file is located at {j2mewtk.dir}\wtklib\devices\DefaultGrayPhone in the binary installation. The shared device property files are located at {j2mewtk.dir}\wtklib\devices\Share in the binary installation.
