Hi, I have upgraded from Tomcat 5.5 to Tomcat 6.0.35 I am getting java.lang.NoClassDefFoundError: org.apache.commons.logging.LogFactory I didn't have this problem before. Note that I have commons-logging already in my web apps WEB-INF\lib And this exception is from a class (custom class) running from a jar in %TOMCAT_HOME%\lib If I drop commons-logging in %TOMCAT_HOME%\lib the exception does not happen BUT now I get exceptions in log4j from inside my web app. I tried also deleting the commons-logging from %TOMCAT_HOME%\webapps\myApp\WEB-INF\lib but no success.
Any idea what is the problem here?
