If you put the contents of your war file in a directory with suffix '.war' inside the deploy directory, JBoss will deploy it and you can edit JSPs directly. Touch WEB-INF/web.xml to trigger a redeployment of the whole web application which will reload classes, resources and configuration.
I need to deploy my app to many servers. I don't want to deploy many files (i.e. exploded my war file manually).
Can I configure JBoss to explode the war file? Currently I only copy my war file to /server/all/deploy.
