Antenna provides a set of Ant tasks suitable for developing wireless Java applications targeted at the Mobile Information Device Profile (MIDP). With Antenna, you can compile, preverify, package, obfuscate, and run your MIDP applications (aka MIDlets), manipulate Java Application Descriptor (JAD) files, as well as convert JAR files to PRC files designed to run on the MIDP for PalmOS implementations from Sun and IBM. Deployment is supported via a deployment task and a corresponding HTTP servlet for Over-the-Air (OTA) provisioning. A small preprocessor allows to generate different variants of a MIDlet from a single source.
