Add the Web service document flows to the source and target participants' B2B capabilities to set up a participant connection between the source and target participants.
Before you set up a participant connection between the Web service user and the Web service provider, you need to set up the gateways that will be used in the participant connection. See Creating gateways.
The source gateway's URL is not used by the Web service. It can be a dummy URL. The source gateway can be used to set the Validate Client IP or Validate Client SSL Cert options on the sender side.
For the target gateway, specify the private URL supplied by the Web service provider. This is where WebSphere Business Integration Connect will invoke the Web service when it acts as a proxy for the Web service provider.
