Hot deployment is a term for deploying or upgrading a web application without having to shutdown and restart the application server.

Tomcat is mostly capable of this.
There are a few gotchas such as the handling of static variables from classes stored in common or shared directories. Also repeated hot restarts or redeploys will cause a slight memory leak to show.

All in all though, it does a good job.
If you need true 24/7 up time and can never afford to shut it down for a moment, then Tomcat also offers clustering capability with session replication so different nodes can be brought down and brought back up without interrupting service to the application.

I agree. Here's the link: http://ej-technologies/jprofiler - if it wasn't for jprofiler, we would need to run our stuff on 16 servers instead of 3.
