  Ubiquitous networking empowered by Beyond 3G networking makes it possible for
mobile users to access networked software services across heterogeneous
infrastructures by resource-constrained devices. Heterogeneity and device
limitedness creates serious problems for the development and deployment of
mobile services that are able to run properly on the execution context and are
able to ensures that users experience the "best" Quality of Service possible
according to their needs and specific contexts of use. To face these problems
the concept of adaptable service is increasingly emerging in the software
community. In this paper we describe how CHAMELEON, a declarative framework for
tailoring adaptable services, is used within the IST PLASTIC project whose goal
is the rapid and easy development/deployment of self-adapting services for B3G
networks.
