Hello, I have some problem trying use log4j with System environment. This is my log4j.xml:

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration PUBLIC  "-//APACHE//DTD LOG4J 1.2//EN" "">

<log4j:configuration xmlns:log4j="">
	<appender name="main" class="org.apache.log4j.ConsoleAppender">
		<layout class="org.apache.log4j.PatternLayout">
			<param name="ConversionPattern" value="%d{HH:mm:ss} %5p [%-20c{1}] %m%n" />

	<appender name="file" class="org.apache.log4j.RollingFileAppender">
		<param name="append" value="false" />
		<param name="maxFileSize" value="10MB" />
		<param name="maxBackupIndex" value="10" />
		<param name="file" value="${CATALINA_HOME}/logs/info.log" />
		<layout class="org.apache.log4j.PatternLayout">
			<param name="ConversionPattern" value="%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n" />

	<category name="org.jboss.logging">
		<priority value="WARN" />
		<appender-ref ref="main" />

	<category name="org.jboss.weld">
		<priority value="INFO" />
		<appender-ref ref="main" />

	<logger name="controller">
		<level value="INFO" />
		<appender-ref ref="main" />
		<appender-ref ref="file" />
	</logger >

I can see the logs on catalina.out, but is not creating the info.log.

Works fine on my computer, lol. Ty,

Does ${CATALINA_HOME}/logs/info.log exist? You might need to create the file and allow Tomcat to write to it.

If catalina.out works fine, you can transfer its permissions to info.log:

sudo chmod --reference /path/to/catalina.out /path/to/info.log
sudo chown --reference /path/to/catalina.out /path/to/info.log
