I've worked with Tomcat, OC4J (Oracle appserver). Both of them support exploded archive deployment, i.e., i extract my WAR contents on the OS filesystem and point to a given directory as my webContent folder from my server configuration. I can then easily change things on the file system and restart the server to reflect the same.
I want to know if JBoss supports such a thing. I'm pretty sure that someone should've got it to work. If so, could you please throw some light on this,
