CWSXM2008E No wired connections to reference 0 and the service message object does not contain a target endpoint.
Explanation
The reference is not connected to any import and a target endpoint was not provided in the service message object. When a reference on a mediation flow component is not wired to any import, then the logic in the mediation flow must set in the ServiceMessageObject (SMO) header the endpoint to be used for invoking the service. This must be set in the SMO prior to calling the Callout node or Service Invoke mediation primitive by the mediation flow. The logic of the mediation flow must ensure that the target endpoint is set. Since the reference is not wired to an import, there is no way that any service can be invoked, since the endpoint for the service has not been specified.
User response
Use the IBM Integration Designer mediation flow editor to inspect the logic in the mediation flow to ensure that all paths to the Callout or Service Invoke primitive have the function to set the target endpoint in the ServiceMessageObject.
