I configured Log4j to log into a file but it is instead logging to stdout.
it creates the log file but it does not write to it, instead to stdout.
Here is my config file:
log4j.rootCategory=INFO, file, mail
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=/path-to/jobs-batch.log
log4j.appender.file.MaxFileSize=10MB
log4j.appender.file.MaxBackupIndex=2
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=[jobs-batch] %p [%t] %c{1}.%M(%L) | %m%n
log4j.logger.org.springframework.jdbc=WARN
# Configuration for receiving e-mails when ERROR messages occur.
log4j.appender.mail=org.apache.log4j.net.SMTPAppender
log4j.appender.mail.To=xxx#xxx.com
log4j.appender.mail.From=xxx#xxx.com
log4j.appender.mail.SMTPHost=mail.xxx.de
log4j.appender.mail.Threshold=ERROR
log4j.appender.mail.Subject=Jobs Batch Error
log4j.appender.mail.layout=org.apache.log4j.PatternLayout
log4j.appender.mail.layout.ConversionPattern=%d %-5p %c %x - %m%n
any ideas?
Thanks
Adjust to suite your needs:
log4j.rootCategory=DEBUG, C
log4j.appender.C=org.apache.log4j.ConsoleAppender
log4j.appender.C.layout=org.apache.log4j.PatternLayout
log4j.appender.C.layout.ConversionPattern=%d{MMddyyyy HH:mm} %-5p %c{1}:%L - %m%n
log4j.appender.C.Target=System.out
Things to check:
What is the name of your Log4j property file? The default is log4j.properties, which is what the Log4j library will look for on startup.
Related to what Thorbjorn asks in his comment, where is the log4j property file located? Placing it in the default package will ensure it's found (by default Log4j searches the classpath).
Optionally specify the location of the log4j property file using the log4j.configuration property when starting the JVM.
i was stupid by myself.
i was using the -Dlog4j.configuration to set my file.
BUT i was also configuring log4j programmatically to use the SAME configuration file.
i still do not understand why it did behave like that since i was just setting the SAME configuration file twice. But once i did it only once it worked as expected.

I want to set default file path for my application, in case ${custom.log.path} is not defined or by any means can't be created than logs should be generated at default location.
I am using spring application, not sure how to configure the default file path.
log4j.properties :
# Root logger option
log4j.rootLogger=DEBUG, file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=${custom.log.path}/Application.log
log4j.appender.file.MaxFileSize=5MB
log4j.appender.file.MaxBackupIndex=10

log4j.appender.file.layout.ConversionPattern=%d [%t] %-5p (%F:%L) - %m%n
Check this topic and answers: Is there a way to specify a default property value in Spring XML?
Spring Framework supports the following syntax:
${my.variable:defaultValue}
I'm using log4j 1.2 and I need to:
log everything (including logging from referenced libraries) to console
log from my code to file (and maybe to console)
Using the following code:
log4j.rootLogger=DEBUG, CONSOLE
log4j.com.mypackage=ALL, CONSOLE, CSV
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.Target=System.err
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.conversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %-5p - %m%n
log4j.appender.CSV=org.apache.log4j.FileAppender
log4j.appender.CSV.File=./myfile.csv
log4j.appender.CSV.Append=false
log4j.appender.CSV.layout=org.apache.log4j.PatternLayout
log4j.appender.CSV.layout.conversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %-5p - %m%n
The logfile is not created.
Other try I done:
If I add CSV appender to rootLogger, then the file is created and filled.
If I add CSV appender to rootLogger and disable it, then the file is just created.
If I log only my logger to console... the it works fine
Do you have any idea to solve?
Thanks
You are missing an important part.
The value has to be
log4j.logger.com.mypackage
Note that you are missing logger in the log definition
How can I disable Struts2 zillions of logs?
I constantly get logs like this:
2012-04-12 23:20:31,487 DEBUG [XWorkConverter.java:388] : Property: menuExpandedOps
I'm using struts 2.0 and standard java logging (I'm not using log4j).
The logging.properties file of the JVM is set by default to INFO, and I already have struts.devMode = false in my struts.properties file.
If you are free to use log4j, i suggest you to use that, since Log4j has the ability to set different log levels for different packages and hence using the log level OFF we can disable logging for a particular package.
In S2 most of the log messages will be from these packages
xwork2
struts2
freemarker
ognl
and a simple property file/xml file in class-path can help you to turn on or off the logging information.
and a simple property file/xml file in class-path can help you to turn on or off the logging information.
For those who want an example:
1) Put log4j.properties inside src (where your packages are):
2) Turn OFF low-level logging:
# root logger option
log4j.rootLogger=DEBUG, stdout, file
# direct log messages to console
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=[%p: %d{yyyy-MM-dd HH:mm:ss} %F:%L] %m%n
# direct log messages to a log file, support file rolling
log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
log4j.appender.file.File=${catalina.home}/logs/sortingmonitor.log
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=[%p: %d{yyyy-MM-dd HH:mm:ss} %F:%L] %m%n
# disable apache low level logging
log4j.category.com.opensymphony.xwork2=OFF
log4j.category.org.apache.struts2=OFF
log4j.category.freemarker.beans=OFF
log4j.category.freemarker.cache=OFF

So, I have the log4j configurations set up and it output to the console just fine. But I need it to output to a file now. I am using Axis2 in Eclipse Galileo.
I edited the default log4j.properties file to this:
Set root category priority to INFO and its only appender to CONSOLE.
log4j.rootCategory=INFO, CONSOLE
log4j.rootCategory=INFO, CONSOLE, LOGFILE
Set the enterprise logger priority to FATAL
log4j.logger.org.apache.axis2.enterprise=FATAL
log4j.logger.de.hunsicker.jalopy.io=FATAL
log4j.logger.httpclient.wire.header=FATAL
log4j.logger.org.apache.commons.httpclient=FATAL
CONSOLE is set to be a ConsoleAppender using a PatternLayout.
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.ConversionPattern=[%p] %m%n
LOGFILE is set to be a File appender using a PatternLayout.
log4j.appender.LOGFILE=org.apache.log4j.FileAppender
log4j.appender.LOGFILE.File=C:\Users\*username*\Desktop\Android\Android_WS\src\wtp\AndroidWS_Log.log
log4j.appender.LOGFILE.Append=true
log4j.appender.LOGFILE.layout=org.apache.log4j.PatternLayout
log4j.appender.LOGFILE.layout.ConversionPattern=%d [%t] %-5p %c %x - %m%n
But the output is still not getting to the Log file. Any help would be much appreciated. Thanks Guys!
Remove line 2:
log4j.rootCategory=INFO, CONSOLE
Also, try using a forward slash, '/' for the directory separator:
log4j.appender.LOGFILE.File=C:/Users/*username*/Desktop/Android/Android_WS/src/wtp/AndroidWS_Log.log
Make sure that your server has write access rights to the log file.
Is there any way to tell to log4j to write its log to the file and to the console?
thanks
there are my properties:
log4j.rootLogger=DEBUG,console,R
log4j.rootLogger=INFO, FILE
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.CONSOLE.Target=System.out
log4j.appender.CONSOLE.layout=org.apache.log4j.PatternLayout
log4j.appender.CONSOLE.layout.conversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %-5p - %m%n
log4j.appender.FILE=org.apache.log4j.RollingFileAppender
log4j.appender.FILE.File=log4j.log
log4j.appender.FILE.MaxFileSize=512KB
log4j.appender.FILE.MaxBackupIndex=3

log4j.appender.FILE.layout.conversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %-5p - %m%n
Your root logger definition is a bit confused.
See the log4j documentation.
This is a standard Java properties file, which means that lines are treated as key=value pairs. Your second log4j.rootLogger line is overwriting the first, which explains why you aren't seeing anything on the console appender.
You need to merge your two rootLogger definitions into one. It looks like you're trying to have DEBUG messages go to the console and INFO messages to the file. The root logger can only have one level, so you need to change your configuration so that the appenders have appropriate levels.
While I haven't verified that this is correct, I'd guess it'll look something like this:
log4j.rootLogger=DEBUG,console,file
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.file=org.apache.log4j.RollingFileAppender
Note that you also have an error in casing - you have console lowercase in one place and in CAPS in another.
Your log4j File should look something like below read comments.
# Define the types of logger and level of logging
log4j.rootLogger = DEBUG,console, FILE
# Define the File appender
log4j.appender.FILE=org.apache.log4j.FileAppender
# Define Console Appender
log4j.appender.console=org.apache.log4j.ConsoleAppender
# Define the layout for console appender. If you do not
# define it, you will get an error
log4j.appender.console.layout=org.apache.log4j.PatternLayout
# Set the name of the file
log4j.appender.FILE.File=log.out
# Set the immediate flush to true (default)
log4j.appender.FILE.ImmediateFlush=true
# Set the threshold to debug mode
log4j.appender.FILE.Threshold=debug
# Set the append to false, overwrite
log4j.appender.FILE.Append=false
# Define the layout for file appender
log4j.appender.FILE.layout=org.apache.log4j.PatternLayout
log4j.appender.FILE.layout.conversionPattern=%m%n
This works well for console in debug mode
log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.Threshold=DEBUG
log4j.appender.console.Target=System.out
log4j.appender.console.layout=org.apache.log4j.PatternLayout
log4j.appender.console.layout.conversionPattern=%d{yyyy-MM-dd HH:mm:ss,SSS} %-5p - %m%n
Write the root logger as below for logging on both console and FILE
log4j.rootLogger=ERROR,console,FILE
And write the respective definitions like Target, Layout, and ConversionPattern (MaxFileSize for file etc).
Thats the exact usecase I was looking for my command line based tool. Wanted to show INFO on console but wanted to log more detailed info to log file. After various suggestion, finally go this solved by using 'log4j.appender.FILE.Threshold'
Something like below.:
log4j.rootLogger=DEBUG,CONSOLE,FILE
log4j.appender.CONSOLE=org.apache.log4j.ConsoleAppender
log4j.appender.FILE=org.apache.log4j.RollingFileAppender
log4j.appender.FILE.File=output/log.log
log4j.appender.CONSOLE.Threshold=INFO
log4j.appender.FILE.Threshold=DEBUG
