Question

I\'d like to generate alarms on my Java desktop application :

• alarms set with a specific date/time which can be in 5 minutes or 5 months
• I need to be able

Answer 1

Of the available options you have listed, IMHO Option 3 is better. As you are looking only for an external trigger to execute the application, CRON or Scheduled tasks are better solutions than other options you have listed. By this way, you remove a complexity from your application and also your application need not be running always. It could be triggered externally and when the execution is over, your application will stop. Hence, unnecessary resource consumption is avoided.
