One oft cited complaint about Java Web Applications is the slow and laborious deployment step. This step seriously undermines the ability to get into a flow state and is generally a major buzz kill. The absense of a deployment step is one reason why people like Ruby on Rails so much.

JSF-Extensions Design Time brings good news for flow-impaired Java Web application Developers: the JMX PhaseListener.

The implementation of this was really simple. I just took Jean-Francios Arcand's JMXDeploy class, modded it ever so slightly, as you can see in the source code, and called it from a PhaseListener.

I did a screencast about it too.
