Location Source is an implementation of Java's Location API (JSR-179). It is intended to give Java applications access to location data on platforms that do not have a JSR-179 implementation of their own. It currently only runs on Windows Mobile using IBM's WebSphere Everyplace Micro Edition (WEME) 6.1.1 bu can easily be extended to run on other platforms. For example, you could use it on any laptop by tying it into SkyHook's Loci API.
J4ME is a library to help with J2ME development. It includes a UI framework for professional-looking and intuitive interfaces, a logging framework to help debugging platform-specific issues found on different phones, a Bluetooth GPS integrated into the JSR-179 Location API, and a library of missing J2ME methods and helpful collections for small devices.
