If your log4j library is included within your EAR file, then check your app server's JVM properties to ensure the log4j.configuration property is set:
- Login to the Glassfish Admin Console (http://[hostname]:4848/)
- For your server, navigate to Configuration > JVM Settings > JVM Options
- If an entry for -Dlog4j.configuration exists, verify that it contains the location of your log4j.xml file
- If an entry do not exist for -Dlog4j.configuration, create one. It must follow the following template: -Dlog4j.configuration=file:///path/to/your/log4j.xml
