  com.cryptovide.log
  (:gen-class)
  (:use
   clojure.contrib.logging))

...

(def logger (org.apache.log4j.Logger/getLogger "A1"))
(def log-levels (vec ( org.apache.log4j.Level/getAllPossiblePriorities)))

(defn start-logging []
  (org.apache.log4j.BasicConfigurator/configure))

main.clj:

(start-logging)
(. logger setLevel (log-levels verbose-level))
