[logback-user] Wire up logback

Hello, I have an application that already has logback 1.1.3 packaged up with it. I want to take the logback.xml configuration that is in the application and override the log path without building a new package. I can currently accomplish this by just adding logback jars to lib/logging/, but that means i have the same jars on the file system twice. Is there a way I can utilize the already loaded jars instead of keeping two locations sync Thanks, Russ
