When using a SoapUI call with Javelin, the WebService call through Javelin fails with the error message: Object reference not set to an instance of an Object. I am also seeing the error message: The ‘Content-Type’ header must be modified using the appropriate property or method. Parameter name: name.
SoapAction field is being passed as "" (null). The wsdl of the service has the action defined as "" (null). Other headers like user-agent, content-type, etc. are being passed as well. The Javelin service call fails, however, SoapUI seems to get the response for the service successfully with same setup.
