Overview The assumption of the availability of port information at design time of service compositions in Service-Oriented Architectures (SOAs) is not valid for an increasing number of hosts on the Internet that do not have a public, static IP address. This paper presents a workflow engine that supports runtime look-up of service endpoints based on a P2P middleware. Using a service identifier based on a DHT identifier, Service Proxy objects that encapsulate port information are downloaded over the structured P2P network from the host where the service is deployed.
