Problem for access RFC through webservice

Hi Experts,

                 I have faced one problem in webservice.I have developed one RFC and created webservice for that function module.Also created a service consumer..When I have called my function module in my SAP server,it is working fine.But when I am going to test it through SOAP testing tool then it is showing the following error..
