Running I/O Delegator in service request mode

When running in service request mode, I/O Delegator uses service calls to invoke the StreamServer application that will process the data delivered via I/O Delegator. The service is exposed via a Service Request input connector configured in the Design Center Project that is exported and deployed to the StreamServer application.

I/O Delegator delivers the data to the StreamServer application via the Service Request input connector. The StreamServer application processes the data and delivers the output via the appropriate output connector. The output can be returned in the response to I/O Delegator if this is enabled in the Design Center Project.

The web service (WSJobSubmit) that controls the communication between I/O Delegator and the StreamServer application is hosted by a service gateway. This service gateway must be running in the same application domain as the StreamServer application.
