validate schema at HTTP receive adapter

hi,

i’m having a problem where i want to raise a SOAP exception at the receive port(one way port) which published as web service. i created a pipeline to validate the input message and right now whenever the input is not as per schema the message will be suspended and the client think it is successful. i cannot change the one-way port to request-response port because the design has been approved.

really appreciate your help.

thanks in advance.
