When I start Tomcat I get the following error:
Jun 10, 2010 5:17:25 PM org.apache.catalina.core.StandardContext start SEVERE: Error filterStart Jun 10, 2010
Check the localhost_yyyy_mm_dd.log OR localhost.yyyy-mm-dd.log logs that Tomcat creates, these typically store that type of info. I wouldn't expect the full stacktrace to be dumped to standard out.
localhost_yyyy_mm_dd.log
localhost.yyyy-mm-dd.log
