Client Server Sample Program

Hello Team

I've tried client server sample program given in examples.

When I start server, not sure on which URI it is coming up and may be because of that client program is not able to make a connection to server URI.

My observation is ' client is not identifying where server is running' and I could not find an option where to fix host & port for server & client program.

@darconeous : Please advise. I've attached sample server & client program.

Thanks
