| $h1 Application Server Integration |
| |
| The Application Server module provides support for integrating Log4j into various Java Application Servers. |
| |
| $h2 Apache Tomcat |
| |
| Log4j may be used as the logging framework for Apache Tomcat. This support is implemented automatically by including |
| the log4j-api, log4j-core, and log4j-appserver jars in the boot classpath. A file named log4j2-tomcat.xml, |
| log4j2-tomcat.json, log4j2-tomcat.yaml, log4j2-tomcat.yml, or log4j2-tomcat.properties must also be placed |
| in the boot classpath. This is most easily done by: |
| |
| 1. Creating a set of directories in catalina home named log4j2/lib and log4j2/conf. |
| 2. Placing log4j2-api-${Log4jReleaseVersion}.jar, log4j2-core-${Log4jReleaseVersion}.jar, and |
| log4j2-appserver-${Log4jReleaseVersion}.jar in the log4j2/lib directory. |
| 3. Creating a file named log4j2-tomcat.xml, log4j2-tomcat.json, log4j2-tomcat.yaml, log4j2-tomcat.yml, or |
| log4j2-tomcat.properties in the log4j2/conf directory. |
| 4. Create or modify setenv.sh in the tomcat bin directory to include |
| ```CLASSPATH=$CATALINA_HOME/log4j2/lib/*:$CATALINA_HOME/log4j2/conf``` |
| |
| $h3 Requirements |
| |
| Requires Tomcat 8.5 or later. |
| |
| $h2 Eclipse Jetty |
| |
| Log4j may be used as the logging framework for Eclipse Jetty. |
| |
| To direct Jetty to use this class, set the system property `org.eclipse.jetty.util.log.class` to `org.apache.logging.log4j.appserver.jetty.Log4j2Logger`. |
| |
| From the command line with: |
| ```-Dorg.eclipse.jetty.util.log.class = org.apache.logging.log4j.appserver.jetty.Log4j2Logger``` |
| |
| Programmatically with: |
| ```System.setProperty("org.eclipse.jetty.util.log.class", "org.apache.logging.log4j.appserver.jetty.Log4j2Logger");``` |
