[jboss-as7-dev] Deployment -- why marker files?

Hi, In AS7 it uses a bunch of 'Marker files' to control and indicate a deployment. Comparing to previous AS 4 I found this is not so convenient. For example if I want to deploy an EJB jar I need to drop it to the /deployments dir and create a .dodeploy marker file. And if my EJB failed to deploy the marker file changed to .fail mark file. In a debug process this deployment can be repeated many times, each time a .dodeploy has to be manually added. And that's for a single EJB. If I have 5 EJB jars deployed I need file marker files manually created. In AS 4 I just drop it and done. I wonder what's the good reason for those marker files? From a user's point of view, for what other purposes could it be to drop something to the deployments directory than for deploying it right away? Thanks Howard
