Service Oriented Environment focuses on the individual service as the main based on which the environment build its architecture, procedures and rules. In this paper we share a summary of research work that has being done over many years tackling the issue of creating a dynamically changing framework that allows providing new services to accommodate newer requests. This will make the framework continuously adapting to new needs that may not exist in the available services. We use web services standards WSDL, WS-Policy and SOAP to handle service description, orchestration rules and service messaging. The orchestration is implemented using graph based to resolve the limitations of WS orchestration using the BPEL standard. The framework is used to generate new E-Learning services not existing in the Learning Management System LMS like the media generator and the course portfolio. These two new composed services have shown to improve the students learning and performance.
