[2.0] Programatically shut down Play 2.0?

[Jostein Austvik Jacobsen]

Is it possible to create a button on a Play 2.0-based website which, when clicked, would stop the website (equivalent of "play stop") ?

Calling System.exit() is enough to shut down the JVM.

What about a graceful restart? Is it possible to stop accepting new requests, wait for all open connections to close, and then restart the instance reloading changes from disk? I mean, programatically in production mode?

What I thought of doing at some point was to set-up a mechanism (for
continuous deployment) which would shut down the JVM with a specific
exit code (e.g. -2) and have the JVM process watched by a linux agent
of sorts (I think one process-watching tool was mentioned on the list
before) which then would restart it after updating the version.

Then simply System.exit(-2).

Yes, it was more of a suggestion to Marconi on how to restart from
within the application. Though it won't do it gracefully (i.e. running
connections will just be cut off).

I have done something similar using HAProxy
