Alrighty....progress I get a response-code: 200 and I can see in the response the message goes through.
Immediately after this response however I get the stack message: -------------------------------------- Jan 19, 2018 1:47:11 AM org.apache.cxf.phase.PhaseInterceptorChain doDefaultLogging WARNING: Interceptor for {urn:test.sale.au/schema/common}RSIService#{urn:test.sale.au/schema/common}SetSale has thrown exception, unwinding now org.apache.cxf.binding.soap.SoapFault: The signature or decryption was invalid -- Sent from: http://cxf.547215.n5.nabble.com/cxf-user-f547216.html
