I am receiving these error messages in the log file during deployment of my application in JBoss. The messages started to appear after I add a log4j jar file to the lib directory in WEB-INF. Can anyone help?

Remove the log4j.jar file from WEB-INF/lib. JBossAS already has that file, so you don't need it. And as you found it causes classloader issues if you have your own copy.
