Subject Re: Logging questions
Date Wed, 13 Jul 2011 16:53:28 GMT
It looks like you have the log4j-over-slf4j bridge on your classpath. Or
some combination of the different logging facilities.

So commons-logging detects log4j and tries to use it. Log4j tries to
delegate to slf4j, but that fails due to the missing implementation class.

Do other parts of your application use log4j or slf4j? If not, can you
remove them from the classpath and try 'just' with commons-logging?
