while calling a apex class generated by wsdl2apex, through anonymous block getting error 'System.CalloutException: Web service callout failed: WebService returned a SOAP Fault: INVALID_SESSION_ID'

Below is the apex class for which I have generated a wsdl
global class DemoWS{
    static webservice String greetings(){
    String s='Happy Holidays';
    return s;
  }
}

Below is my wsdl which I have used in another org to generate apex class---

Using the above wsdl the generated apex is below

response_x = response_map_x.get('response_x');
return response_x.result;
}
}
}

and the anonymous block where I have used the below code to run that apex is

demo.DemoWS stub = new demo.DemoWS();
stub.greetings();

I have used correct endpoint in remote settings .

Please help .

Thanks in advance.
