How to wait for messages alert

[Jas Oberai]

Hi Friends,
I have a java web application.I want to automate it.Right now,when I click the "submit button",my appln reads messages from the phone sim card(attached to my pc),queries the database and then automatically sends a response back to the originator.
How to automate this,such that my java program automatically knows that a new message has arrived on the phone and read that message and send the response back.
Please suggest some easy way.
Thanks

You might have to keep polling the phone to check for new messages.
See java.util.Timer class on how to execute your program after
every 'n' minutes.

That was one way,I was thinking.But isn't there any way to listen to some port or something that notifies you when a new message arrives...thanks a lot.

Hi,
I wrote this class to run every 5 seconds but it executes only once,can someone please tell me where i am going wrong

public class Test{
Timer timer = null; 
  
    public Test(int seconds) { 
        timer = new Timer(); 
        timer.schedule(new RemindTask(), seconds*1000); 
    } 
 
    class RemindTask extends TimerTask { 
        public void run() { 
        RMessages rm = new RMessages();
        Message rmsg = rm.getMessage();
        System.out.println("Messaage is:" + rmsg);
            System.out.println("Time's up!"); 
      timer.cancel(); //Terminate the timer thread 
        } 
    } 
 
 

public static void main(String[] ar) {
 //  while(true){
   System.out.println("About to schedule task."); 
       new Test(5); 
       System.out.println("Task scheduled.");
   //}
 
}
 
}

Thanks

Remove this line.

timer.cancel(); //Terminate the timer thread
