I am totally new to SLF4J/Logback, and I am using WebLogic Server 11. We previously were using log4j and used an external file and some custom class so that we could update the log4j file at runtime and not have to reboot the server or application. We didn't use the WebLogic Server console to change the logging level. So if I want to use slf4j/logback, is there anything special I have to do for placing jars in the bootclasspath or lib directory. As well as when I want to have runtime changes to the log level, what is the best way to do this with slf4j/logback and WebLogic Server? I read this blog for help: http://blog.kares.org/2009/10/log4j-logging-without-log4j.html Thanks for your help...jay -- View this message in context: http://old.nabble.com/Logback-with-WebLogic-Server---Suggestions-tp30829362p...
