Abstract
Service Level Agreement or contract is a document that captures the functional and QoS levels agreed between the service provider and the consumer. In a service-oriented environment, individual services can be suitably composed to create a composite service. Whenever a new version of a composite service is created, for the same service consumer, in order to satisfy the change in consumer requirements, the respective contracts also need to be versioned. Likewise, whenever a service consumer is dynamically provided different versions of the services based on their requirements, the respective contracts also need to be activated, automatically. In this context, this study proposes an approach for, dynamic reconfiguration of a service-oriented application, which has been offered as a composite service with its corresponding version of the contract. This dynamic reconfiguration approach has been tested by applying it to a sample SOA based e-Shopping application.
