What is required to make DynamicTcpClientApplication also return data with the send interface?

[Syrou]

I'm trying to wrap my head around how to make the DynamicTcpClientApplication also give back the response data sent with:

	@MessagingGateway(defaultRequestChannel = "toTcp.input")
	public interface ToTCP {

		public void send(String data, @Header("host") String host, @Header("port") int port);

	}

Just changing from void to byte[] is not enough. What is needed to make sure a client can get the response from a tcp request back through the interface?

Use gateways instead of channel adapters - see this commit garyrussell@901363d
