Hello !
I have developed a remote object that runs on a server and is communicating with the client through tcp.
This remote object does call functions of another remote object B and communicates with it through http.
Everything was ok until i changed the implementation of the remote object B and now it implements an interface.
Instead of RemotingConfiguration.Configure("RemoteobjectB.config")

and then RemoteObjectB obj=new RemoteObjectB();

i now do

ChannelServices.RegisterChannel(new HttpChannel());
IRemoteObjectB obj = (IRemoteObjectB)Activator.GetObject(typeof(IRemoteObjectB),
"http://someaddress:8989/RemObj);
where IRemoteObjectB is the interface of the remote object b

but i get this error despite the fact that i have already registered a httpchannel for communication .

System.Runtime.Remoting.RemotingException: Cannot create channel sink to connect to URL . An appropriate channel has probably not been registered.
