Apache Error Log
the help of Apache Commons Logging library. That library is a thin wrapper above different logging frameworks. It provides Tomcat with the ability to log hierarchically across various mysql error log log levels without the need to rely on a particular logging implementation. Since Tomcat 6.0, Tomcat uses a private package-renamed implementation of Apache Commons Logging, to allow web applications to use their own independent copies of the original Apache Commons Logging library. In the default distribution this private copy of the library is simplified and hardcoded java error log to use the java.util.logging framework. To configure Tomcat to use alternative logging frameworks for its internal logging, one has to replace the logging library with the one that is built with the full implementation. Such library is provided as an extras component. Instructions on how to configure Tomcat to use Log4j framework for its internal logging may be found below. A web application running on Apache Tomcat can: Use system logging API, java.util.logging. Use logging API provided by the Java Servlets specification, javax.servlet.ServletContext.log(...) Use any logging framework of its choice. The logging frameworks used by different web applications run independently of each other. See class loading for more details. The exception to this rule is java.util.logging, if it used directly or indirectly by your logging library. That is because it is loaded by the system and is shared across web applications. Java logging API — java.util.logging Apache Tomcat has its own implementation of several key elements of java.util.logging API. This implementation is called "JULI". The key component the

I uploaded a WAR using the manager interface and tried to start the application but get a pretty generic error on the Web interface saying it couldn't be started. I am trying to find the logs to determine why my war won't start (I suspect low memory as i'm on a small VPS) but I don't know where they are. /var/lib/tomcat6/logs is empty. My Tomcat http://serverfault.com/questions/127640/where-are-my-tomcat-logs splash page reliably informs me of the following; Tomcat is installed with CATALINA_HOME in /usr/share/tomcat6 CATALINA_BASE in /var/lib/tomcat6, following the rules from /usr/share/doc/tomcat6-common/RUNNING.txt.gz.

The simplest solution is to change the JULI permissions to: // These permissions apply to JULI grant codeBase "file:${catalina.home}/bin/tomcat-juli.jar" { permission java.security.AllPermission; }; Obviously, there may be security issues I'm not aware of, but I really can't be bothered to dig deeper - I've spent too long on this myself. share|improve this answer answered Jul 24 '12 at 19:18 Auspex 1615 Thanks for the u

Whereas, I have an older instance where the logs are in: /opt/tomcat7/logs/ I'm not sure why there is a disparity in this, as both applications use the tomcat7 container, but this seems to be the state of things to date. share|improve this answer answered Dec 3 '12 at 16:29 Paul Sanwald 5,38512242 The location was changed in one of the late 2012 AMI updates. –Ken Liu Apr 6 '13 at 21:15 add a comment| up vote 6 down vote By default, AWS Elastic Beanstalk log output from Tomcat is written to /opt/tomcat7/logs/tail_catalina.out.

This is where the log file paths are defined. –sean_m Sep 2 '14 at 5:56 add a comment| 2 Answers 2 active oldest votes up vote 1 down vote I usually find any files using file command and filter the results using grep. It helps on many situation. For your case it is possible that your tomcat6 log file would be located in some other place. So you can use following command to locate it, you would get few results then it would be easier to look the actual path: sudo find / -type f | grep tomcat| grep log For example if I want to find all the log files of apache2 then I have to execute this (I don't hav
