Calling function by clicking a button in JSP?

Question

Can I call specific function (present in my JSP page) by clicking a button?

Answer 1

I am using TimerTask in my JSP page to print some message:
<%
                  Timer timer = new Timer();
                  TimerTask monitorTimerTask = new Monitor();
                  timer.schedule(monitorTimerTask,1000,1000);
%>
<%!
     private class Monitor extends TimerTask{
          int i = 0;
          public void run(){
                   System.out.println("TimerTask ["+i+"]");
                   ++i;
%>And to stop the TimerTask daemon, I created the following function:
<%!
     public void stopTimerTask(){
          if(monitorTimerTask != null){
               System.out.println("Stopping the Timer Task");
               monitorTimerTask.cancel();
%>Now, I am trying to call funtion "stopTimerTask()" by click of a button in JSP page. The function is being called BUT the daemon keeps on printing the text message to the console. It means the above function is not able to stop the TimerTask.
What to do?
Please help!
Thanks,
