Thanks for the reply Charles. It's a CentOS 5.4 system with Sun JDK 1.5 and tomcat-5.5.28 version. Tomcat was not installed using CentOS package manager, but it is a core binary package downloaded from tomcat project site.
I downloaded a fresh copy of tomcat package and took a diff of it against tomcat in-use. Attached below is a snippet of it. On further digging around I found following configuration related to logs: * $CATALINA_HOME/common/classes/log4j.properties: contains a line which is spitting out logs to tomcat.log So I guess I am using log4j for internal logging and they are going to tomcat.log file. * $CATALINA_HOME/conf/logging.properties I don't see any configuration that specifies catalina.out. But the reason I see logs in catalina.out are because of following reasons: ** Tomcat startup/shutdown information that goes to Stdout and Stderr ** My lazy programming practice: Not using log4j or any other logging API. Am I understanding it correctly? Any thoughts? Thanks, jM.
