Having frameworks that allow the implementation of personal agents on mobile devices, such as JADELEAP, is essential towards a future massive deployment of service-providing agents and their widespread social acceptance. In this paper we show how JADE-LEAP may be used to implement a personal agent on a PDA. This agent belongs to a multi-agent system that allows the user to request a taxi in a city. The personal agent communicates wirelessly, via Bluetooth, with the rest of the agents of the multi-agent system, in order to find the most appropriate taxi to serve the user.
