3.4. Component Service

A component service is used to expose the functionality of an implementation as a service. All component services have a contract, which can be a Java interface, WSDL portType definition, or a set of named data types (interface.esb). Component services are private to an application, which means a component service can only be invoked by other components in the same application. In order to expose a component service to consumers external to the application, a component service can be promoted to a composite service. A component service can be promoted multiple times to create different composite services.
