I assume that you are talking about hot deployment so that you can deploy without restaring yr server.
If thats the case this feature is available in Jboss3.2.1 and you dont have to do anything else, other then using JDK 1.4 which has this hot deploymen feature. Please correct me if I am wrong here.
I am using Jboss3.2.1 and JDK 1.4. Hot Deployment seems to be working but when I make a change to and existing class I've been having to restart JBoss.
Maybe I have something configure incorrectly.
