Hi, I don't know J2me. But, I have one book regarding this. And from that book I have got the following code which help you in Sending/Receiving SMS on J2ME device. Try to execute it.

public boolean connectSMSServer() 
{
   try 
  {
    messageConnection messageConnection = (MessageConnection)Connector.open("sms://:  " + port);
    messageConnection.setMessageListener(this);
  }
  catch (Exception e) 
  {
  }
}

public void sendTextmessage(String address,String message) 
{
  try 
  {
    TextMessage textMessage = (TextMessage)messageConnection.newMessage( MessageConnection.TEXT_MESSAGE, address);
    textMessage.setPayloadText(message);
    messageConnection.send(textMessage);
  } 
  catch (Exception e) {
  }
}

public void receiveTextMessage() 
{
  try 
  {
    Message message = messageConnection.receive();
    if (message instanceof TextMessage) 
    {
      TextMessage textMessage = (TextMessage)message;
    } 
    else 
    {
     }                   
  } 
  catch (Exception e) {
  }
}

public synchronized void notifyIncomingMessage(MessageConnection conn) 
{
  synchronized (this)
  {
    notify();
  }
}

public void closeConnection() 
{
  if (messageConnection != null) 
  {
    try 
    {
      messageConnection.setMessageListener(null);
      messageConnection.close();
    } 
    catch (Exception e) 
   {
    }
    }
  }
}

Hi, I have created one source code which will help you to achieve this. Just use this to send sms using J2ME.

import javax.microedition.midlet.*;
import javax.microedition.lcdui.*;
import javax.microedition.io.*;
import com.siemens.mp.gsm.*;
public class smsone extends MIDlet implements CommandListener
{
private Form form;
private Command cmdOk,cmdExit;
private TextField msg;
public smsone()
{
}
public void startApp()
{
Display dis=Display.getDisplay(this);
form=new Form("Send SMS");
msg=new TextField("Dest No",null,160,2);
cmdOk=new Command("Send",Command.SCREEN,0);
cmdExit=new Command("Exit",Command.SCREEN,0);
form.append(msg);
form.addCommand(cmdOk);
form.addCommand(cmdExit);
form.setCommandListener(this);
disp.setCurrent(form);
}
public void pauseApp()
{
}
public void destroyApp(boolean b)
{
}
public void commandAction(Command c,Displayable dis)
{
if(c==cmdOk)
{
int rep=0;
String err_msg="";
try
{
SMS sms = new SMS();
String dest_no=msg.getString();
dest_no=dest_no.trim();
rep=sms.send(dest_no,"Sent from j2me");
msg.setLabel(""+rep);
}
catch(Exception e)
{
err_msg="error :"+e.getMessage();
System.out.println("error has occur:"+e);
e.printStackTrace();
}
}
else if(c==cmdExit)
{ 
notifyDestroyed();
}
}
}

Hi, you can send sms in java with the following two techniques.
1)Using SMTP to Send a sms:

import java.io.*;
import java.net.InetAddress;
import java.util.Properties;
import java.util.Date;
import javax.mail.*;
import javax.mail.internet.*;
import javax.activation.*;

public class EmailSMS
{
String To;
String From;
Striring Subject;
String Text;
String MailHost;
String lasterror;
public static void main(String[] args) throws Exception
{
EmailSMS SMS = new EmailSMS();
SMS.setMailHost("mail.domain.com");
SMS.setTo("123456789@messaging.intel.com");
SMS.setFrom("name@domain.com");
SMS.setSubject("");
SMS.setText("Hello World!");
boolean ret = SMS.send();
if (ret)
{
System.out.println("SMS was sent!");
}
else
{
System.out.println("SMS was not sent - " + SMS.getLastError());
}
}
public EmailSMS()
{
To = null;
From = null;
Subject = null;
Text = null;
MailHost = null;
lasterror = "No method called.";
}

public void setTo(String to)
{
To = to;
}

public String getTo()
{
return To;
}

public void setFrom(String from)
{
From = from;
}

public String getFrom()
{
return From;
}

public void setSubject(String subject)
{
Subject = subject;
}

public String getSubject()
{
return Subject;
}

public void setText(String text)
{
Text = text;
}

public String getText()
{
return Text;
}

public void setMailHost(String host)
{
MailHost = host;
}

public String getMailHost()
{
return MailHost;
}

public String getLastError()
{
return lasterror;
}

public boolean send()
{
int maxLength;
int msgLength;
if (To.indexOf("mobile.att.net") > 0)
{
maxLength = 140;
}
else if (To.indexOf("messaging.nextel.com") > 0)
{
maxLength = 280;
}
else if (To.indexOf("messaging.sprintpcs.com") > 0)
{
maxLength = 100;
}
else
{
maxLength = 160;
}
msgLength = From.length() + 1 + Subject.length() + 1 + Text.length();
if (msgLength > maxLength)
{
lasterror = "SMS length too long.";
return false;
}

Properties props = System.getProperties();
if (MailHost != null)
{
props.put("mail.smtp.host", MailHost);
}

Session session = Session.getDefaultInstance(props, null);
try
{
Message msg = new MimeMessage(session);
if (From != null)
{
msg.setFrom(new InternetAddress(From));
}
else
{
msg.setFrom();
}
msg.setSubject(Subject);
msg.setText(Text);
msg.setRecipients(Message.RecipientType.To,InternetAddress.parse(To, false));
msg.setSentDate(new Date());
Transport.send(msg);
lasterror = "Success.";
return true;
}
catch (MessagingException mex)
{
lasterror = mex.getMessage();
return false;
}
}
}


2)Using a Third-Party Wireless Platform to Send a Message in java:

import com.simplewire.sms.*;

public class SimplewireSMS extends java.lang.Object
{
public static void main(String[] args) throws Exception
{
SMS sms = new SMS();
sms.setMsgPin("1005101234");
sms.setMsgFrom("Joe");
sms.setMsgCallback("6165551212");
sms.setMsgText("Hello World From Java SMS!");
System.out.println("Submitting SMS To Simplewire...");
sms.msgSend();
if (sms.isSuccess())
{
System.out.println( "The message was sent!" );
}
else
{
if(sms.getErrorCode().equals("345"))
{
System.out.println("Sample request was success.");
System.out.println("However, could not recognize carrier.\n");
}
else
{
System.out.println("The message was not sent!");
System.out.println("Error Code: " + sms.getErrorCode());
System.out.println("Error Description: " + sms.getErrorDesc() + "\n");
}
}
}
