you can edit the file located under ${catalina.home}/conf/logging.properties setting org.apache.catalina.core.ContainerBase.[Catalina].[localhost].level = FINE,
restart tomcat and then post the output? tomcat is not complaining about superfluous jars, but about missing tlds definitions and adjusting the log level will show you some more details
(it will show you where tomcat is looking for the missing tlds and a suggestion on how to solve your issue)
