Hello neha,

Welcome to the Java Programming Forums.

I know of two solutions you can try.

WMA (Wireless Messaging API) is a wireless messaging api defined in MIDP 2.0. These apis are designed to handle text, binary and multipart messages. To make a connection, the application obtains an object implementing the MessageConnection from the Connector class by providing an URL connection string that identifies the address.

/* Make a connection */
public boolean connectSMSServer() 
{
  try 
  {
    messageConnection messageConnection = 
      (MessageConnection)Connector.open("sms://:" + port);
    messageConnection.setMessageListener(this);
  }
  catch (Exception e) {
  }
}
 
/* Send text message */
public void sendTextmessage(String address,String message) 
{
  try 
  {
    //creates a new TextMessage
    TextMessage textMessage = (TextMessage)messageConnection.newMessage(
            MessageConnection.TEXT_MESSAGE, address);
    textMessage.setPayloadText(message);
    messageConnection.send(textMessage);
  } 
  catch (Exception e) {
  }
}
 
/* Recieve text message */
public void receiveTextMessage() 
{
  try 
  {
    Message message = messageConnection.receive();
    if (message instanceof TextMessage) 
    {
      TextMessage textMessage = (TextMessage)message;
    } 
    else 
    {
      //Message can be binary or multipart
    }                   
  } 
  catch (Exception e) {
  }
}
 
/* Notify Incoming Message */
public synchronized void notifyIncomingMessage(MessageConnection conn) 
{
  //notiy thread of incoming message
  synchronized (this)
  {
    notify();
  }
}
 
/* Close Connection */
public void closeConnection() 
{
  if (messageConnection != null) 
  {
    try 
    {
      messageConnection.setMessageListener(null);
      messageConnection.close();
    } 
    catch (Exception e) {
    }
    }
  }
}

WMAPI allows Java ME applications to access messaging functionalities, as sending and receiving SMS and MMS messages. This article explains how to use it to send a simple text message.

public boolean sendSms(String number, String message){
    boolean result = true;
    try {
      //sets address to send message
      String addr = "sms://"+number;
      // opens connection
      MessageConnection conn = (MessageConnection) Connector.open(addr);
      // prepares text message
      TextMessage msg =
      (TextMessage)conn.newMessage(MessageConnection.TEXT_MESSAGE);
      //set text
      msg.setPayloadText(message);
      // send message
      conn.send(msg);
      conn.close();
    } catch (SecurityException se) {
        // probably the user has not allowed to send sms
        // you may want to handle this differently
        result = false;
    } catch (Exception e) {
        result = false;
    }
    return result;
  }
