SOAP API method errors

Can anyone tell me whether the below SOAP method looks correct. To me it seems this autogenerated method does not contain the correct information, but I may be wrong. I am trying to understand whether it is my script which is wrong or the SOAP method.

function result = SpectrumMatch(obj,SpectrumMatchRequest) %SpectrumMatch(obj,SpectrumMatchRequest) % % Input: % SpectrumMatchRequest = (SpectrumMatchRequest) % % Output: % result = (spectrumLineInfo)

% Build up the argument lists. values = { ... SpectrumMatchRequest, ... }; names = { ... 'SpectrumMatchRequest', ... }; types = { ... 'SpectrumMatchRequest', ... };

% Create the message, make the call, and convert the response into a variable. soapMessage = createSoapMessage( ... 'Metlin', ... 'SpectrumMatch', ... values,names,types,'rpc'); response = callSoapService( ... obj.endpoint, ... 'SOAP/Metlin#SpectrumMatch', ... soapMessage); result = parseSoapResponse(response);

The errors I get are:

??? Error using ==> callSoapService at 130 SOAP Fault: SOAP-ERROR: Encoding: Cannot find encoding
