1) Verify that the URL being used is correct. Log into Service Desk Manager server and run: http://localhost:8080/axis/services/USD_R11_WebService?wsdl
It's possible that the port number is incorrect and a different port number is being used to run Web Services. GRLoader will use Web Services to connect to CMDB.
2) Once you find the correct port number and URL, change the GRLoader command to use the right URL/port.
