ashishnegi / problem-quartz.clj

My problem with quartz.

	Thanks for quartzite.
	I am trying to make quartz work with jdbc store. However, i find that new jobs are not triggering.
	I can see all new jobs and triggers in my database. My `defjobs` from another files also work.
	It is just that jobs are not getting triggered.
	My scheduler code is :

	```clj
	(ns theophrastus.utils
	(:require [clojurewerkz.quartzite.scheduler :as qsched]
	[clojurewerkz.quartzite.triggers :as qtrigger]

Last active September 4, 2016 16:55

	-- Sometimes we want to decode value of type a from a json list of a.. but each with some little differences..
	-- Like server sends json: [{"name" : "a"},{"name" : "b"}]
	-- and we have

	type alias Player =
	{ name : String
	, color : Color
	}

	-- color is view specific and server is not sending it..
