I'm trying to build a development environment for a Java/Spring web application in Tomcat. I've recently used Grails and, as you can see, in Grails there is a file scanner that intercepts changes on Java/Groovy files and automatically, and hot deploys on Tomcat server.

I have looked at the Grails source code and I can see that it uses a Tomcat7 embedded server, but I can't understand how the hot deployment works.

It don't use the standard Tomcat7 context redeploy feature.

Someone knows how Grails hot deployment works?

Grails use Spring Loaded as it's reload agent, you can look how it works.
