Synopsis

emulator [options] [classname]

Description

The emulator command provides the execution environment and application management software for the J2ME Wireless Toolkit. Its functionality and command-line interface are both very similar to those of midp, but it supports the use of device skins together with a configuration file, so different devices can be emulated without the need to modify any code. Although the emulator can be used from the command line, it is most frequently accessed indirectly via the KToolBar interface provided by the Wireless Toolkit.

Options

The operation of the emulator command is determined by the options supplied to it. There are three different modes of operation:

• Displaying information using the -help, -version, and -Xquery options. Here, the classname argument is not required, and the command exits after printing the required information.

• Running a MIDlet from the local system or by loading from a network server, but without installing it. This mode of operation uses the -classpath option together with a class name or the -Xdescriptor option, which may or may not be accompanied by a class name.

• Using the emulator’s application management software to install, run, list, or delete MIDlet suites. This mode of operation uses the -Xjam option.

The following list describes emulator options:
