Out of interest, what's the advantage to being "more enterprise" in this case? Having a webserver with a working REPL seems like a rather useful thing to have.
Yes, that is very useful, in a way that's not normally possible with java.
But it is very nice to just give a .war file to techops. They know what to do with it, and how to keep such an application running and reboot it should it be needed. It's nice to not have to write custom init.d scripts.
