i am trying to send sms through java program.i am usining ubuntu 6.04.i am using modem MC35i.i use the jSMSEnjine.jar and rxtxcomm.jar.
these are the following program.

import org.jsmsengine.*;
import java.util.*;


class SendMessage
{

public static void main(String[] args)
{
int status;

// Create jSMSEngine service.
CService srv = new CService("Com2",9600);
//CService srv = new CService("COM2",9600);



System.out.println();
System.out.println("SendMessage(): sample application.");
System.out.println(" Using " + srv._name + " " + srv._version);
System.out.println();
try
{
// Initialize service.
srv.initialize();

Thread thread =Thread.currentThread();
thread.sleep(1000);
System.out.println(srv);

// Set the cache directory.
srv.setCacheDir(".\\");

// Set the phonebook.
// srv.setPhoneBook("../misc/phonebook.xml");
// Connect to GSM device.
status = srv.connect();
// Did we connect ok?
int st=CService.ERR_OK;
System.out.println(st);
System.out.println(status);
if (status == CService.ERR_OK)
{
// Set the operation mode to PDU - default is ASCII.
srv.setOperationMode(CService.MODE_PDU);

// Set the SMSC number (set to default).
srv.setSmscNumber("");

// Print out GSM device info...
System.out.println("Mobile Device Information: ");
System.out.println(" Manufacturer : " + srv.getDeviceInfo().getManufacturer());
System.out.println(" Model : " + srv.getDeviceInfo().getModel());
System.out.println(" Serial No : " + srv.getDeviceInfo().getSerialNo());
System.out.println(" IMSI : " + srv.getDeviceInfo().getImsi());

System.out.println(" Battery Level : " + srv.getDeviceInfo().getBatteryLevel() + "%");
System.out.println(" Signal Level : " + srv.getDeviceInfo().getSignalLevel() + "%");

// Create a COutgoingMessage object and dispatch it.
// *** Please update the phone number with one of your choice ***
// String smsLengthTest="Hi"+"\nTesting is going on.Test for sending unlimited number of charecter.So you will get N number of SMS.Initially I trancate the whole string by 70 charecter.Later I will put it upto 90 charecter.Some chararecter should kept for header portion.I don't know the total number.It is just test.If you got the sms u should appreciate me...This is Ripon...I have written sms program";
