send sms from web application

I am trying to send sms from java application using SMPPSim as SMS gateway and smppapi

This is the code to send SMS

public class SyncTransmitter extends SMPPAPIExample {

private Log logger = LogFactory.getLog(SyncTransmitter.class);

public SyncTransmitter() {
}

public void execute() {
    try {
        logger.info("Binding to the SMSC");

        myConnection = new Connection("localhost", 2775);
        myConnection.autoAckLink(true);
        myConnection.autoAckMessages(true);

        BindResp resp = myConnection.bind(
                Connection.TRANSMITTER,
                "smppclient1",
                "password",
                null);
        /**
        BindResp resp = myConnection.bind(
                Connection.TRANSMITTER,
                "smppclient1",
                "password",
                systemType,
                sourceTON,
                sourceNPI,
                sourceAddress);

         */
        if (resp.getCommandStatus() != 0) {
            logger.info("SMSC bind failed.");
            System.exit(1);
        }

        logger.info("Bind successful...submitting a message.");

        // Submit a simple message
        SubmitSM sm = (SubmitSM) myConnection.newInstance(SMPPPacket.SUBMIT_SM);
        sm.setDestination(new Address(1, 8, "9988776655"));
        sm.setMessageText("This is an example short message.");
        SubmitSMResp smr = (SubmitSMResp) myConnection.sendRequest(sm);

        logger.info("Submitted message ID: " + smr.getMessageId());

        // Unbind.
        UnbindResp ubr = myConnection.unbind();

        if (ubr.getCommandStatus() == 0) {
            logger.info("Successfully unbound from the SMSC");
        } else {
            logger.info("There was an error unbinding.");
        }
    } catch (Exception x) {
        logger.info("An exception occurred.");
        x.printStackTrace(System.err);
    }
    }
}

public static void main(String[] args) {

    System.out.println("Test");
    SyncTransmitter st = new SyncTransmitter();
    st.execute();
    System.out.println("Done….");
}

This is the SMPPSim Console output

I am not able to understand what is the problem

Also please suggest some open source SMS Gateway

I'm not sure about this lib, but you can use smslib. It requires a mobile device which is GSM-capable which will act as a virtual SMS aggregator.
