Mobile Device Tools provides a set of tools to help J2ME MIDP developers with Java implementations on new devices. The three tools are "Keys", which tests which events are generated by which keys and finds the key codes of non-standard keys, "Specs", which finds the basic device information and the support for the various optional JSRs, and "ClassBrowser", which provides information about feature support by allowing the user to explore the hierarchy of the classes present on the device.
