The pervasive and mobile computing scenario is characterized by the heterogeneity of devices used to access services, and by frequent changes in the user?s context. This paper presents the integration of two existing frameworks into a context-aware content provisioning system oriented to mobile users. External Web contents can be automatically tailored according to a wide range of context data, including device capabilities, available bandwidth, location, user preferences. The tailoring process is human intervention free. In order to demonstrate the feasibility of our solution, we have developed a prototype location-based service that takes advantage of this architecture.
