Log4j writes into catalina.out

I want to redirect application specific logger into a separate file from tomcat/logs/catalina.out.

Here is the content of log4j.xml file content which is residing at tomcat/lib folder

<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">

 <appender name="RollingFiles" class="org.apache.log4j.DailyRollingFileAppender">

        <param name="file" value="${catalina.home}/logs/application.log"/>        
        <param name="DatePattern" value="'.'yyyy-MM-dd"/>
        <layout class="org.apache.log4j.PatternLayout">
    <param name="ConversionPattern" value="%p-%d-{%C}-%t-%x-%m%n"/>
        </layout>
 </appender>

 <logger name="com.company">
        <level value="debug"/>
 </logger>

 <root>
        <priority value ="debug" />
        <appender-ref ref="RollingFiles" />
 </root>
</log4j:configuration>

Here is the content of logging.properties presented inside tomcat/conf folder

handlers = 1catalina.org.apache.juli.FileHandler, 2localhost.org.apache.juli.FileHandler, 3manager.org.apache.juli.FileHandler, 4host-manager.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler

.handlers = 1catalina.org.apache.juli.FileHandler, java.util.logging.ConsoleHandler


1catalina.org.apache.juli.FileHandler.level = FINE
1catalina.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
1catalina.org.apache.juli.FileHandler.prefix = catalina.

2localhost.org.apache.juli.FileHandler.level = FINE
2localhost.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
2localhost.org.apache.juli.FileHandler.prefix = localhost.

3manager.org.apache.juli.FileHandler.level = FINE
3manager.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
3manager.org.apache.juli.FileHandler.prefix = manager.

4host-manager.org.apache.juli.FileHandler.level = FINE
4host-manager.org.apache.juli.FileHandler.directory = ${catalina.base}/logs
4host-manager.org.apache.juli.FileHandler.prefix = host-manager.

java.util.logging.ConsoleHandler.level = FINE
java.util.logging.ConsoleHandler.formatter = java.util.logging.SimpleFormatter


org.apache.catalina.core.ContainerBase.[Catalina].[localhost].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].handlers = 2localhost.org.apache.juli.FileHandler

org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/manager].handlers = 3manager.org.apache.juli.FileHandler

org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/host-manager].level = INFO
org.apache.catalina.core.ContainerBase.[Catalina].[localhost].[/host-manager].handlers = 4host-manager.org.apache.juli.FileHandler

But still I am getting all logger output in catalina.out and application.log, but I don't want application specific log (i.e logger name="com.company") in catalina.out. Kindly help me on this.

Tomcat version : 7.0.35
Java : 1.7.0_45
Log 4j : log4j-1.2.16.jar

The issue is, I referred a jar in my project which has org.pentaho.di.core.logging.LogWriter class. It by default adding console logger into the root logger.

The fix is, removed it from LogWriter

Try to move your log4j.xml file under your app root directory : webbapps/[your app]/WEB-INF/classes

This way you are not depend on a specific tomcat installation for your logging and you can deploy your app on any tomcat instance without changing the default tomcat configuration.
