I am using Jooq along with JAX-RS to create a REST API.
I have the following dependencies in my maven pom file log4j 1.2.7 and jooq 3.9.4
I have put the log4j.properties file in resources folder. Here are the contents of the file:
log4j.rootLogger=DEBUG, stdout, file
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=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=/home/ps06756/log4j-application.log
log4j.appender.file.MaxFileSize=5MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
Still, Jooq is not logging the SQL statemennts being executed.
How should I correct this problem.
Please check if you have logback or slf4j on your classpath as that is the first logger the JooqLogger tries to find on the classpath.
If it fails it tries log4j and after that it falls to java.util.logger.
When it does find logback or slf4j but you don't have any configuration you will not see anything being logged.

I have implemented the log4j with following properties.
# Root logger option
log4j.rootLogger=DEBUG, stdout, file
# Redirect log messages to consol
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=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
# Redirect log messages to a log file, support file rolling.
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=/home/../log4j-application.log
log4j.appender.file.MaxFileSize=5MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
It is working on localhost where in server side it log nothing . I guess above are the general configuration. Is there something i am missing here? I use TomEE on both client and server.Also i used the logger as following. It also does not write in local file. Only logger seems to work on client.
private static final Logger LOGGER = Logger.getLogger(MyClass.class);
I think problem with this line
log4j.appender.file.File=/home/../log4j-application.log
Please use (if you have a log folder)
log4j.appender.file.File=log/log4j-application.log
I am using probe along with tomcat. My application which is deployed in tomcat 8.5 use log4j for its logging.
This is Log4j.properties configuration :
# Root logger option
log4j.rootLogger=DEBUG, file
log4j.logger.org.hibernate.SQL = DEBUG, file
log4j.logger.org.hibernate.type = TRACE, file
# Redirect log messages to a log file, support file rolling.
log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
log4j.appender.file.File=${catalina.base}/logs/my-app.log
log4j.appender.file.Append=true
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
log4j.appender.file.DatePattern='.'yyyy-MM-dd
log4j.appender.file.rollingPolicy.ActiveFileName=${catalina.base}/logs/my-app.log
log4j.appender.file.rollingPolicy.FileNamePattern=${catalina.base}/logs/archive/my-app-%d{yyyy-MM-dd}.log.gz
Everything is fine and i could fine my logs, but when the server restart i lost everything.
It seams like probe delete the log file after reboot
Am i missing something in the configuration on my application or even in the prob side?
# Root logger option
log4j.rootLogger=DEBUG, stdout, file
# Redirect log messages to console
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.Target=System.out
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
# Redirect log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
#outputs to Tomcat home
log4j.appender.file.File=${catalina.home}/logs/my-app.log
log4j.appender.file.MaxFileSize=5MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
can you check above code?
put all properties in your log4j properties file
i have an application, i have applied log4j, but i can't able to create log file inside jboss application.
when i put absolute path of system in log4j.appender.file.File= D:/log/application.log it was working fine but when i put log4j.appender.file.File= ${jboss.server.home.dir}/log/application.log it is not working.
# Root logger option
log4j.rootLogger=DEBUG, stdout, file
# Redirect 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=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
# Redirect log messages to a log file, support file rolling.
log4j.appender.file=org.apache.log4j.DailyRollingFileAppender
#log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File= ${jboss.server.home.dir}/log/application.log
log4j.appender.file.MaxFileSize=5KB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
try using $JBOSS_HOME instead of ${jboss.server.home.dir}.. so it becomes
log4j.appender.file.File= ${JBOSS_HOME }/log/application.log
I don't understand why my Log4J is not logging to file. Ive been looking many similar posts but none helped me. I configured all correctly, but it doesn't log to the file.
Let me show you, this is the config log4J.properties:
# Root logger option
log4j.rootLogger=INFO, file, stdout
# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=log.out
log4j.appender.file.ImmediateFlush=true
log4j.appender.file.MaxFileSize=1024MB
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.Append=true
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
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=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
And this is how I use the Logger:
import org.slf4j.Logger;
import org.slf4j.LoggerFactory;
...
private Logger logger = LoggerFactory.getLogger(GameBoardService.class);
...
logger.info("log this text into file....");
Try to specify your base package for the logging
log4j.logger.[your own class base package ]=INFO
e.g.
log4j.logger.org.springframework=WARN
log4j.logger.org.hibernate=WARN
Be specific with the log path to enable you to easily locate the path, e.g. below.
log4j.appender.file.File=/var/logs/log.out
Furthermore, /var/logs/log.out is created in Windows as C:\var\logs\log.out and in Linux as /var/logs/log.out and there is no need to switch path slashes according to OS. Just a reminder, ensure you have permission to the specified path.
I'm getting two warnings.
log4j:WARN No appenders could be found for logger (com.org.Resolver).
log4j:WARN Please initialize the log4j system properly.
How to resolve it?
My java class name Resolver.java
In java class i'm calling
private static Log log = LogFactory.getLog(Resolver.class);
You need to put log4j.properties or log4j.xml in your classpath. So, create file name log4j.properties and replace the content with below:
# Root logger option
log4j.rootLogger=INFO, DEBUG, stdout, file
# Redirect 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=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
# Redirect log messages to a log file, support file rolling.
log4j.appender.file=org.apache.log4j.RollingFileAppender
#. represents the current folder (usually the project root folder)
log4j.appender.file.File=./logging.log
log4j.appender.file.MaxFileSize=5MB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c{1}:%L - %m%n
