JRebel maps your project workspace directly to your running application. When a developer makes a change to any class or resource in their IDE the change is immediately reflected in the application, skipping the build and redeploy phases. For further information see their site: http://www.zeroturnaround.com/jrebel
We have two personal licenses of JRebel including their Enterprise Add-on (a combined value of $159 USD) to offer this month.
To take part in the promotion all you have to do is send an email to me at firstname.lastname@example.org with your name and email address. Please mark JRebel as the subject title.
