Nailgun has been a boon to me. I don't believe Nailgun has a problem

John,
Is like I am missing something? This thread mentioned making periodic tasks,
there was a java example to it. However, what you posted I am yet to figure
out how to make a periodic tasks possible.

My recollection from list and IRC was that (aside from random nailgun

VimClojure relies on Nailgun, with a bunch of people on this list
using it with Clojure every da

Overhead from starting and stopping the JVM every couple of minutes
would probably be unacceptable. My understanding is that solutions
iles , and rotate those files sometimes.
I am sure there are more fancy solutions than cron, and some that
don't require megabytes of XML as the usual Java stuff

Personally, I think Java-ish is the way to go here. John's actor lib
is pretty nifty, but it is relying on implementation details of the
threading o
How about:
(import '(java.util.concurrent Executors TimeUnit))
(let [s (Executors/newSingleThreadScheduledExecutor)]
(.scheduleAtFixedRate s
#(try
(println "I did it again")
(catch Exception e
(.printStackTrace e)))

What is a good and simple way to run periodic tasks in Clojure? I need
to run a simple function every couple of minutes. And make sure that
if it throws an exception that it won't kill the periodic task.
I come from a Spring world where XML, Timers, Jobs and Quartz rule the
world,
