Using a System Participant to Identify the Web Service Endpoint
A system participant is a logical identifier for a connection to an external system - in this case, a web service endpoint. An endpoint defines the URL that will be used to contact the web service.
A task or event that calls a web service must use a system participant that identifies the endpoint of the web service that is to be invoked. This information is used at runtime to map the call to the web service.
When you select or import a concrete WSDL operation binding (), or select, import or generate an abstract WSDL operation (), a system participant is automatically created and assigned to the calling task or event’s Endpoint Name. (The system participant’s name is taken from the portType of the chosen operation.)
See System Participant Shared Resource Properties for more information about the configuration of this system participant.
