Service Oriented Architecture (SOA) promotes the utilization of available services to develop completely new applications in a context which has not been foreseen as these services were implemented. Unfortunately the interfaces respectively the behaviour of a service often do not fit exactly to the new domain. Slight changes would be necessary to reuse them in the new environment. This paper presents an approach to integrate dynamic AOP into a SOA platform to adapt existing services at runtime to new requirements. Services can then be reused without the need of stopping and redeployment.
