Timer instance grabs 100% of CPU time

Question

Hi Javapeople,
I have a java process I want to run at regular time intervals, once a day when the code is actually deployed.
I sort of have it working but the problem is that java.exe takes all of the CPU time on my NT 4 Workstation machine and everything else running is starved.
My code for scheduling is:
public class PacTimer {
Timer timer;
public PacTimer(int seconds) {
timer = new Timer();
timer.scheduleAtFixedRate(new PacTask(), seconds*1000, 20000);
class PacTask extends TimerTask {
public void run()
new PacMailer();
public static void main(String args[]) {
System.out.println("About to schedule task.");
new PacTimer(5);
System.out.println("Task scheduled.");
while(true);
In this case, the process to schedule is 'new PacMailer();' and it runs every 20 seconds.
What's the best way of scheduling something as a background process to run at regular intervals does anybody know? Thanks very much!

Answer 1

I have a similar problem in an application, instead of waiting for a schedule time it listen to events. I think the solution must be multi-threading, we can use a low priority thread to hold the bucle, but I have to check it
