@Configuration
public class FtpConfiguration {
    @ServiceActivator(inputChannel = "ftpLS")
    @Bean
    public FtpOutboundGateway getGW() {
        FtpOutboundGateway gateway = new FtpOutboundGateway(sf(), "ls", "payload");
        gateway.setOption(Option.NAME_ONLY);
        gateway.setOutputChannelName("results");
        return gateway;
    }

    @Bean
