I am using weblogic 10.3.6 and Iam trying to use log4j1.2 for logging purposes.
I have created log4j.xml in src/main/resources.
But log4j is not creating any file or nor even logging on console.
I tried giving jvm property -Dlog4j.debug=true but even that is not printing anything on console.
Any pointers?

Ok. So I was using JRebel and It was not creating any logs. After disabling JRebel it worked.

Log4j logging doesn't work on wildfly-10.1.0.Final, even logfile is not created. Application seems to be working

This is my configuration file of log4j, on Windows works fine but on centos only create the in /tmp/ControllerDebug.log file and nothing is written in it.
I have checked that it isn´t a problem of permissions.
My server is jboss.

Well, I resolved this adding jboss-deployment-structure.xml file with this information:
<jboss-deployment-structure>
<deployment>
<!-- Exclusions allow you to prevent the server from automatically adding
some dependencies -->
<exclusions>
<module name="org.apache.log4j" />
<module name="org.apache.commons.logging" />
</exclusions>
</deployment>
</jboss-deployment-structure>
I have this log4j.xml file which should only log from INFO Level
but i was also getting the WARN Level also in my log .
<?xml version="1.0" encoding="UTF-8"?>

This is the output i was getting in my Custom Appender and RollingFileAppender
LOgged One is 2013-06-23 01:05:55,954[main] FATAL(Hi.java:<main>:14)- This is a fatal Message
LOgged One is 2013-06-23 01:05:55,965[main] WARN (Hi.java:<main>:15)- This is a warn Message
please tell me how to avoid this .
This behavior is normal. Setting a logger to a specific level value indicates that you want that level AND all level above.
Levels are :
TRACE
DEBUG
INFO
WARN
ERROR
FATAL
OFF
If you want only the INFO level, you have to use filters on your appenders :
<filter type="org.apache.log4j.varia.LevelMatchFilter">
<acceptOnMatch value="true" />
<levelToMatch value="INFO" />
</filter>
<filter type="org.apache.log4j.varia.DenyAllFilter" />
My requirement is to log the messages to 3 separate log files.
I am using 3 appenders in a JBOSS server.
Three of them need to work in the way such as
1.RollingFileAppender, consoleAppender work for 'INFO' and 'ERROR' modes.
2.DailyRollingFileAppender for 'ERROR' mode and for a specific category only.
I have tried lots of combinations like changing the priority value and the categories, but I have so far found no way in which all the three work simulatneously. Either fileAppender and ConsoleAppender work(logging both ERRROR and INFO) and the DailyRollingFileAppender does not or DailyRollingFileAppender does but the other two log only ERRORS not INFO.
Please tell me a way so that the three of them work.
Below mentioned is the log4j.xml I am using.
<?xml version="1.0" encoding="UTF-8"?>

You can restrict an appender to only log a certain level by using filter class specifying which level you would want to log . See the sample code below
<appender name="TRACE" class="org.apache.log4j.ConsoleAppender">
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="[%t] %-5p %c - %m%n" />
</layout>
<filter class="org.apache.log4j.varia.LevelRangeFilter">
<param name="levelMin" value="DEBUG" />
<param name="levelMax" value="DEBUG" />
</filter>
</appender>
I have a class which events I want to log. Say, there are 2 levels: debug and error. How can I log errors to an errorFile and debug info to a debugFile?
So that I use log4j.xml there is a filter mechanism, but it seems to work only for different categories not inside one class.
Please, help to newbie. =)
You have to define and use two appender with different Threshold like this:
<?xml version="1.0" encoding="UTF-8" ?>
<!DOCTYPE log4j:configuration SYSTEM "log4j.dtd">
<log4j:configuration xmlns:log4j="http://jakarta.apache.org/log4j/">
<!-- Error -->
<appender name="ErrorFile"
class="org.apache.log4j.RollingFileAppender">
<param name="Threshold" value="error"/>
<param name="file" value="log.err" />
<param name="MaxFileSize" value="10MB" />
<param name="MaxBackupIndex" value="10" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p %d %C.%M (%L) - %m%n" />
</layout>
</appender>
<appender name="LogFile"
class="org.apache.log4j.RollingFileAppender">
<param name="Threshold" value="debug"/>
<param name="file" value="log.log" />
<param name="MaxFileSize" value="10MB" />
<param name="MaxBackupIndex" value="10" />
<layout class="org.apache.log4j.PatternLayout">
<param name="ConversionPattern" value="%-5p %d %C.%M (%L) - %m%n" />
</layout>
</appender>
<logger name="foo.bar" additivity="false">
<level value="debug" />
<appender-ref ref="LogFile" />
<appender-ref ref="ErrorFile" />
</logger>
<root>
<priority value="warn" />
<appender-ref ref="ErrorFile"/>
</root>
</log4j:configuration>
This question is also answered in the log4j FAQs.
Just found the LogToAppenderByLevel solution (here) which may be also helpful for you.
