Amazon webservice sample project not working.

I have imported the WSDL
http://webservices.amazon.com/AWSEComme ... rvice.wsdl
& started working on it.

I am always getting the soap response as


 
     
        aws:Client.MissingParameter
        The request must contain the parameter Signature.
       
            b0da3244-857a-465c-9371-485ecb7b056e
       
     
 


Why is it so???

    Hey,

    You need to understand the WSDL Contract frist, which defines the input out parameters and the data format.

    I believe your are seeing because of wrong data for any of the parameter in the request. or you may need to specify the security certificate x.509 to invoke the service.

    see  aws:Client.MissingParameter tag in the response which cleary says some data in the request is wrong or some parameters which the service expects is missing.

    Hope this helps,

    Thanks,
    Raj
