Understanding Creating Component Interface-Based Services
PeopleSoft Integration Broker enables you to take an existing component interface and create a service that can be used to invoke the component interface. Further, it creates service operations, including request messages and response messages (if appropriate). The system creates an inbound any-to-local routing for the service operation version, as well as handlers for each method you choose to include in the service.
All service operations you generate from component interfaces are synchronous service operations.
