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? -mike On Tue, Jul 12, 2011 at 1:36 PM, Jason Pyeron <jpye...@pdinc.us> wrote: > > -----Original Message----- > > From: Rick Curtis [mailto:curti...@gmail.com] > > Sent: Tuesday, July 12, 2011 14:00 > > To: users@openjpa.apache.org > > Subject: Re: Logging questions > > > > What do you have set for a configuration property?
