I\'m having some problems putting my log4j.properties file on classpath. I can use it when I\'m developing (Eclipse Indigo) but, when I export my app as a JAR, I can\'t.
I tried the answer of Jesper, and at first it didn't work. Then I tried with
Class-Path: lib/ lib/log4j-1.2.15.jar
And it worked after that.
