Unable to instantiate logger class 'com.mysql.jdbc.log.Log4JLogger'

I recently upgraded from jboss 4.03SP1 to 4.04GA and the following message appears when I run my web app: Unable to instantiate logger class 'com.mysql.jdbc.log.Log4JLogger'.

While the app appears to be running as normal from a user view it is producing this stacktrace. If I deploy to jboss 4.03SP1 it runs as normal. Do you have any ideas on how to resolve this?

Thanks

Niklas

you probably forgot to include the mysql.jar in your new jboss environment.

Thank you thebugslayer, you are correct. What I had to do was just copy the mysql jar file to jboss4.0.5GA\server\default\lib and then it works.Niklas
