From Quartz Scheduler's website
Quartz is a full-featured, open source job scheduling service that can be integrated with, or used along side virtually any Java EE or Java SE application - from the smallest stand-alone application to the largest e-commerce system. Quartz can be used to create simple or complex schedules for executing tens, hundreds, or even tens-of-thousands of jobs; jobs whose tasks are defined as standard Java components that may executed virtually anything you may program them to do. The Quartz Scheduler includes many enterprise-class features, such as JTA transactions and clustering.
Here is a quick blog post comparing the the Java version to the Ruby Version.
- Quartz 2.0 support
- All required JARs included
- This version doesn't support :at option. :cron and :every options are supported
- Support for Jobs with DisallowConcurrentExecution annotation set (pass :disallow_concurrent => true to schedule method)
- Support for interrupting jobs (example in the test file)
Install with
$ gem install quartz-jruby
Example code
require 'quartz'
class TestScheduler
include Quartz::Scheduler
schedule(:say_hello_5, :every => 5) { puts "every 5 seconds" }
schedule(:say_hello_5_dc, :cron => "0/5 * * * * ? ", :disallow_concurrent => true) { puts "every 5 seconds"; sleep(8) }
end
TestScheduler.instance.run
