The development of value added services is currently still very time and cost consuming. The need for specific user generated and in particular business-to-business services demands for efficient service development methods. This paper presents a service creation environment that supports the application developer to compose a service based on reusable components and to describe the business process through a control logic. For the service description a language that has been optimized for business processes is suggested: the Business Process Execution Language (BPEL). However, BPEL has not been developed for control of specific, in particular real time, communication services in heterogeneous networks.Therefore the paper presents a parser translating the business process description into Java code and supporting the deployment of the service in a service execution environment based on JAIN SLEE. The provided elementary communication Service Components hide the underlying heterogeneous communication networks. Thereby the developer does not need any detailed knowledge of communication protocols and is able to focus on the application logic instead. This leads to new opportunities for rapid and efficient service creation using a new Service Creation Environment (SCE) with higher level of abstraction and automated service generation.
