Which Java web frameworks provide hot-reload?

Question

I'd like to know which Java web application frameworks do provide a "hot reload" capability, i.e. allow to develop applications and have them redeployed on the server "almost instantly" (i.e. in less than a few seconds).

I the Java world, Play! has it out of the box, but what I'm looking for is a more exhaustive list.

Other examples that I'm aware of include: Nuxeo WebEngine, provided you're using Eclipse and the right plugin, or, in the Python world, Django and Pylons (when using the "--reload" option).

Answer 1

As far as I know, you can do hot reload with almost every java framework if using jrebel. Some frameworks have some kind of hot-deploy built in, as noted in other answers.
