Hi, 

I am trying to invoke Swipe Clock, an external server through SOAP from Salesforce. I have generated apex class from wsdl file. Generated class is :

        private String[] field_order_type_info = new String[]{'AddEmployeeResult'};
    }
}

Code snippet through which I am invoking the server is:

mc2csComScci m = new mc2csComScci();
mc2csComScci.AuthHeader a = new mc2csComScci.AuthHeader();
a.userName = 'testaccount';
a.password = 'password';
a.site = '1';

mc2csComScci.EmployeeWebInterfaceSoap e = new mc2csComScci.EmployeeWebInterfaceSoap();

String result = e.AddEmployee('12344','mathurtest','ptest','test','test','test','313065406','test','test','test','','',1,12,2,2,2,2,'324545','','','','','','','','',1);

system.debug('result is '+result);

Error received is:

System.CalloutException: Web service callout failed: WebService returned a SOAP Fault: System.Web.Services.Protocols.SoapException: Server was unable to process request. 

But I tried the same wsdl file with SOAP UI , it ran successfully providing desired output.

My instincts are that I am not setting the auth header parameters properly. But dont know for sure. If  anybody has any ideas, please help.

Thanks,

Pragati
