Service oriented technologies allow Service Based Applications (SBAs) to be easily built by composing independent services available in a network and provided by many actors under conditions that may change in time. Therefore services need to be dynamically selected and composed when an SBA is required along with parameters representing the service delivery conditions. In this paper we propose to use a chemical computational approach to model the process of selecting the required service functionalities with the required conditions as an evolving and always running middleware mechanism. The chemical evolving behaviour of the middleware allows to take into account environmental changes coming from both the providers and users side.
