Is it somehow possible to create mock service in soapUI without having wsdl file? All I have is sample request and responses. I think that should be possible to generate WSDL from request and response examples with soapUI but I'm not able to find any tutorials about it.
You can just trick SOAPUi with some dummy WSDL, at least with a single request/response definition! Just replace the requests it generates with the XML document you wanted. You an also add additional requests with entirely different request/responses by copy and pasting!
