What would you like to know? In a nutshell, hot deploy is the ability to drop your 
application into the deploy directory while the server is running. If there is no app 
there it will be deployed fresh. If there is an 
earlier version of the app there, it will replace the existing deployed app 
with the new one, without shutting down the server.

In our initial testing, we have been able to hotdeploy with no apparent interruption 
to actiuve clients. It does seem to flush all the caches, which makes sense. After 
all, it is replacing the entity beans.

It works by periodically checking the timestamp onthe ear. If it sees it change, it 
redeploys. So, you can redeploy an existing deployed app just by 
touching it.

Let us know what other questions you have, but it might be best if you did so on the 
jboss-user list (or on the new web based discussion system). This 
list is supposed to be reserved for issues concerning the devleopment of jBoss itself.

I shall be telling this with a sigh
Somewhere ages and ages hence:
Two roads diverged in a wood, and I -
I took the one less traveled by,
And that has made all the difference.
