Dear Harendra,
There can be two reasons for this error. Either the server application that you've created is not running or, if running, it's listening on a different port no.
Please ensure that the server and client applications both use the same port numbers, channels and formatters. Also try to rename the object uri so that it contains only a single period, e.g. try using
http://localhost:8082/customers.rem instead of
http://localhost:8082/myobjects.customers.rem.
Regards,
