Re: Call function periodically
Should you prefer using Java Concurrent, please have a look at what these guys did: http://code.google.com/p/parfait/ <http://code.google.com/p/parfait/>They succesfully merged *JSR-275*, the Units of Measure API with elements in java.util.concurrent, allowing a far greater flexibility with regards to TimeUnits than the plain JDK enum provides. Also great for conversion between units, e.g. Parfait uses it for Bit/sec or TB/h, etc. On Thu, Sep 2, 2010 at 11:20 AM, Werner Keil wrote: > You could also use Quartz. > > Werner > > > On Thu, Sep 2, 2010 at 11:18 AM, wrote: > >> > This has to be done independently of the activity of the users on the >> web application >> Whats not clear to me is if you will be updating a UI or not... unless you >> are, then why use JavaScript?

You could also use Quartz.

Re: Call function periodically
Quartz is nice but if you need something simple to happen every minute
just use plain Java:
timer = new Timer();
timer.scheduleAtFixedRate(new TimerTask() {
@Override
public void run() {
// do something
}
}
}, 0, 6L);

Hi, you should look at quartz integration provided by ChenilleKit : http://www.chenillekit.org/chenillekit-quartz/index.html 2010/9/1, Mite : > > I need to have a function called every one minute from the moment the > application is deployed on the server, that does some database row updates. > This has to be done independently of the activity of the users on the web > application.

Call function periodically
I need to have a function called every one minute from the moment the application is deployed on the server, that does some database row updates. This has to be done independently of the activity of the users on the web application. Even if there are no users using the application, this call has to be done. Is there any way of doing this in Tapestry5?
