The development of specific communication services is currently still very time and cost consuming. The need for specific business-to-business services, in particular for medium and small sized enterprises, 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 hiding 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. For service creation the developer describes the business process through elementary communication service components and a control logic based on the Business Process Execution Language (BPEL). A parser translates the business process description into Java code and supports the deployment of the service in a service execution environment based on JAIN SLEE. The service creation environment supports fast and individual adaptation of business processes to changing requirements.
