RE: Timer implementation with servlet

[Aaron Smuts]

For one, it looks like you are using the wrong schedule method if you
want it to repeat.  Also, the delay is in millis.  So, you have it set
for 1 second.

If you want it to repeat, you have to use the 3 arg method.  

timer.schedule(new SessionTrack(), 0, 6);

.util.TimerTask,%20long)

Timer implementation with servlet

[Jignesh Patel]

Hi All,
I am trying to implement timer with servlet but it works only at the time of 
loading only while I schedule it to work after every 1 minute. 
What is the reason for not working later on?

My servlet code is as follows:
public class TimerServlet extends GenericServlet implements SingleThreadModel 
{
public void init(ServletConfig config) throws ServletException {
Timer timer = new Timer();
System.out.println("timer started");
timer.schedule(new SessionTrack(),1000); 
}
public void service(ServletRequest arg0, ServletResponse arg1) throws 
ServletException, IOException {

}
public String getServletInfo() {
 return null;
}

}
And code for TimerTask is as follows:

public class SessionTrack extends TimerTask {
 public void run(){
System.out.println("sending email");
Mailer mailer = new Mailer();
mailer.sendMail("profile","[EMAIL PROTECTED]");
 }
}
