Hello,
I am building a community website using Grails and I want to implement user notifications exactly like stackoverflow.com. For instance, user will get notified for new events ('You have new comments', 'one of your favorite has changed'...) either by email or in his mailbox anytime he returns to the website.
I suppose that this is a common problem and I'd like to hear what easy solution do you advice for implementing the back-end in Grails realm. For instance, is Java Message Service a recommended solution for this?
Thank you.
