This is an ESB user forum question, not a developer forum question.
Still, I can attempt to help, if:
1. Required: you provide me with your WSDL (CustomerIdentityRequest.wsdl)
2. Required: you provide me with your full server.log, at INFO level.
3. Optional: you provide me with a sample HTTP request, including all headers and body
What is happening is that the SOAPProxy could not find a match between soapaction->binding, or operation->binding. Providing me with the information above will help me tell you WHY.
