Tomcat 5.5 Takes The Apache Avenue To Commons Logging

This is a quick reference to the loggind of Tomcat 5.5.

You will need to down load the following jars:

1.  Apache Commons Logging  commons-logging.jar
2.  Log4J (Wait A Mintue) *
   
• This requires little discussion, see below
3. Copy the commons logging and log4j jar in to the Tomcat  commons/lib directory : /usr/local/tomcat/common/lib
4. Then copy the log4j configuration file depending on your version of log4j as discussed below:

---

At this point startup Tomcat and tail [Remember?] the tomcat.log to see that your configuration worked.  After you get it up and running read the docs to configure log4j for your personal liking!

---

*[When downloading insrure that the version dowload and the configuratin files match]:

A. When downloading log4j and choosing  log4j-1.2.13.jar the file  log4j.properties must be place in the Neptune:~ zapcaster$ ls /usr/local/tomcat/common/classes/. A sample configuration is below:

# # Configures Log4j as the Tomcat system logge # # # Configure the logger to output info level messages into a rolling log file. # log4j.rootLogger=INFO, R # # To continue using the "catalina.out" file (which grows forever), # comment out the above line and uncomment the next. # #log4j.rootLogger=ERROR, A1 # # Configuration for standard output ("catalina.out"). # log4j.appender.A1=org.apache.log4j.ConsoleAppender log4j.appender.A1.layout=org.apache.log4j.PatternLayout # # Print the date in ISO 8601 format # log4j.appender.A1.layout.ConversionPattern=%d [%t] %-5p %c - %m%n # # Configuration for a rolling log file ("tomcat.log"). # log4j.appender.R=org.apache.log4j.DailyRollingFileAppender log4j.appender.R.DatePattern='.'yyyy-MM-dd # # Edit the next line to point to your logs directory. # The last part of the name is the log file name. # log4j.appender.R.File=/usr/local/tomcat/logs/tomcat.log log4j.appender.R.layout=org.apache.log4j.PatternLayout # # Print the date in ISO 8601 format # log4j.appender.R.layout.ConversionPattern=%d [%t] %-5p %c - %m%n # # Application logging options # #log4j.logger.org.apache=DEBUG #log4j.logger.org.apache=INFO #log4j.logger.org.apache.struts=DEBUG #log4j.logger.org.apache.struts=INFO

The good news is this is how you can rename the file to your liking.  The bad news is, its not XML.  However, that is what the item B option is all about. Version log4j and choosing  logging-log4j-1.3alpha.

# # Application logging options # #log4j.logger.org.apache=DEBUG #log4j.logger.org.apache=INFO #log4j.logger.org.apache.struts=DEBUG #log4j.logger.org.apache.struts=INFO Neptune:~ zapcaster$ cat ~/bin/xml.lotj_1.3.xml                            <?xml version="1.0" encoding="UTF-8" ?>  <!DOCTYPE configuration>   <configuration xmlns="http://logging.apache.org/">   <!-- <configuration xmlns="http://logging.apache.org/" debug="true"> -->   <!-- Create a rolling file appender called "T" for the Tomcat system log -->   <appender name="T" class="org.apache.log4j.rolling.RollingFileAppender">    <!-- Log files should use today's date and rotate at midnight -->      <rollingPolicy class="org.apache.log4j.rolling.TimeBasedRollingPolicy">    <!-- Set the path and file name pattern for your Tomcat log files -->       <param name="FileNamePattern" value="/usr/local/tomcat/logs/tomcat_nept_.%d.log"/>      </rollingPolicy>      <layout class="org.apache.log4j.PatternLayout">       <param name="ConversionPattern" value="%d [%t] %-5p %c - %m%n"/>      </layout>     </appender>    <!-- Configure the root appender -->     <root>      <appender-ref ref="T"/>  <!-- Set your root logging level: debug, info, warn, error or fatal -->  <level value="info"/> </root>  <!-- Configure the log level for Struts -->  <!--  <logger name="org.apache.struts">  <level value="debug"/>  </logger > --> <!-- Configure the log level for Velocity --> <!--  <logger  name="org.apache.velocity.runtime.log.SimpleLog4JLogSystem">  <level value="warn"/> </logger >  --> </configuration>
