java - smslib の Java: smslib を使用してメッセージを送信するための構築エラー

Question

lib smslib-v3.5.3でメッセージの例を送信するために、プロジェクトにlib smslibをインストールしました。libのセットアップについては、Webサイトsmslib.orgのすべての指示に従いました。しかし、私はエラーを見つけました。

 public class SendMessage{
public void doIt() throws Exception
{
    OutboundNotification outboundNotification = new OutboundNotification();
    System.out.println("Example: Send message from a serial gsm modem.");
    System.out.println(Library.getLibraryDescription());
    System.out.println("Version: " + Library.getLibraryVersion());
    SerialModemGateway gateway = new SerialModemGateway("modem.com9", "COM9",                 9600, "InterCEL", "");
    gateway.setInbound(true);
    gateway.setOutbound(true);
    gateway.setSimPin("0000");
    gateway.setSmscNumber("+84920210006");
    Service.getInstance().setOutboundMessageNotification(outboundNotification);
    Service.getInstance().addGateway(gateway);
    Service.getInstance().startService();;
    System.out.println();
    System.out.println("Modem Information:");
    System.out.println("  Manufacturer: " + gateway.getManufacturer());
    System.out.println("  Model: " + gateway.getModel());
    System.out.println("  Serial No: " + gateway.getSerialNo());
    System.out.println("  SIM IMSI: " + gateway.getImsi());
    System.out.println("  Signal Level: " + gateway.getSignalLevel() + " dBm");
    System.out.println("  Battery Level: " + gateway.getBatteryLevel() + "%");
    System.out.println();
    OutboundMessage msg = new OutboundMessage("0987623500", "Hello");
    Service.getInstance().sendMessage(msg);
    System.out.println(msg);
    System.out.println("Now Sleeping - Hit <enter> to terminate.");
    System.in.read();
    Service.getInstance().stopService();
}

public class OutboundNotification implements IOutboundMessageNotification
{
    public void process(AGateway gateway, OutboundMessage msg)
    {
    }
}

public static void main(String args[])
{
    SendMessage app = new SendMessage();
    try
    {
        app.doIt();
    }
    catch (Exception e)
    {
        e.printStackTrace();
    }
}

}
