Service Capability Interaction Manager (SCIM)-type functionality is provided at a horizontal service layer in an Service Oriented Architecture (SOA)-based approach. SCIM composition is provided at multiple levels, including the level of composition where servlets have full access to the context information of the service layer. SCIM composition also occurs at the level of an application dispatching messages to multiple applications/services for processing the messages. The functionality at the service layer also can be programmed using policies, such that routing decisions can be made dynamically as the result of processing conditions and actions. An incoming message can result in a Web service being triggered that in turn triggers a BPEL or SOA workflow, the workflow calling multiple operations to process the message as a result of a routing table or header, environmental and contextual information at the service level, and other information such as user preference or presence information.
