Spring is ignoring commons-logging.jar

I am getting following stacktrace while deploying my web application on Tomcat v6. commons-logging.jar is already included in my class path but still Spring is ignoring it.

You didn't say HOW you're including the jar in your classpath. You should put this jar in the WEB-INF/lib directory of your WAR file.
