Run method at a certain time of the day

[Pichdude]

Hi,

I am wondering if it is possible to have a method run at a certain time of a day? I want to send and e-mail to all users that have an unanswered message stored in the database of the CRM system I am building. The message should be sent i.e. at 3PM every day.

Regards

Hi again (sorry to bump this thread)

I am wondering, is the Timer class the best solution for wanting to do something at the same time every day? It looks like it sets a delay (for example 24h) for when it is suppose to do it next time. But it adds the delay to when it is finished so if it take a few seconds to do the task everytime it will be a small displacement everytime. Is there any better solution in Java or do I have to settle with this?

Best regards

Have you tried rescheduling the timer after each time it executes ?

Have a look at Quartz.

Just an opinion: wouldn't it be better to use OS features to do that?
