I have one synchronus SOAP <--> Proxy scenario. We are maintaining XSD validation to validate the incoming data from partner system.
Currently whenver there is any validation error at sender channel level, partner system gets only "Server Error" message and not the descriptive error. It is difficult for them to understand what is the exact issue with the payload.
When tested from SOAP UI, I get all relevant information as a error response in SOAP call.
I added one standard fault message in Sender Service Interface, but to no effect...
Please let me know if someone can give some input here ??
