Hi guys

I try to create Custom web service for call it from external application

1. Created simple apex class in sandbox 
global class MyWebService {    webService static Integer SumValue(Integer a, Integer b) {
        return a + b;
    }
}
  
// Test class for the previous class.
@isTest
private class MyWebServiceTest {
  testMethod static void testSumValue() {
    Integer x = MyWebService.SumValue(5,10);
  }
}
2. Deployed to production

3. Get Seeeion ID from Enterprise WSDL

When i Try to call SumValue from MyWebService   

Request (SoapUI) 
<soapenv:Envelope xmlns:soapenv="http://schemas.xmlsoap.org/soap/envelope/" xmlns:myw="http://soap.sforce.com/schemas/class/MyWebService">
