Grails background process

Question

I am fairly new to Grails and I have a requirement that I don't know how to implement. I need to make a process that will be running along the side with Grails application and making remote calls, process received data and writing it to DB so that Grails application can make use of it.

So far I figured that I need to leverage domain controllers, but I am not sure how to make a separate process that is constantly running in the background and updating DB.

Is it possible? Can I get references or code examples. Thank you.

Your best bet is Quartz via the http://grails.org/plugin/quartz or http://grails.org/plugin/quartz2 plugins. I've used the quartz plugin and the Job classes you create are artifacts (like controllers, services, etc.) so they support dependency injection. Services are the best place to do transactional database work, so inject one or more services into your Job classes to handle database work.

The quartz2 plugin is newer so you may have more luck using it in current versions of Grails, but it might not have all of the features of the older plugin.
