No gateways are defined SMSlib

Question

I am trying to learn to use SMSlib to send sms using ZTE MF631 usb modem. Here is my code:

        Service.getInstance().startService();
        SerialModemGateway gateway = new SerialModemGateway("modem.com5","COM5", 115200, "ZTE", "MF631");

        gateway.setInbound(true);
        gateway.setOutbound(true);
        gateway.setSimPin("0000");
        gateway.setSmscNumber("+9779800009000");

        try {

           Service.getInstance().addGateway(gateway);
           OutboundMessage outboundMsg = new OutboundMessage("+9779843669921", "Hello there!");
           Service.getInstance().sendMessage(outboundMsg);
        } finally {
            gateway.stopGateway();
            Service.getInstance().removeGateway(gateway);
            Service.getInstance().stopService();
        }

When I run my code I get the following error:

org.smslib.SMSLibException: No gateways are defined.

I think you are missing something like this before you start service:

Service.getInstance().addGateway(gateway);

Here is SMSlib example.
