iWay components include listeners or emitters. Listeners are channels through which documents reach the iWay Service Manager processing flow. Each listener handles a specified protocol such as FTP or HTTP. Emitters are channels through which documents leave the process flow on a specified protocol.
Components differ from exits, which are application-oriented and intended to be easily written by end users. Components are usually more complicated, provide no application logic, and are thus document-agnostic. The exit interface is a published API, and is consistent across iWay Service Manager releases. Exits run in the iWay Service Manager container. Components, on the other hand, are release specific, and may need to be modified as the needs of the iWay Service Manager container change. Components run outside of the iWay Service Manager container.
