I wrote the following in my log4j.properties 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{ABSOLUTE} %5p %c{1}:%L - %m%n
log4j.logger.org.springframework.web = TRACE, stdout
But I'm just getting the init logging. What should I do so as to get detailed logging so as to get the trace whenever i enter a url in my browser.
Its very simple to log the execution of program :
1) Add log4j dependency in pom.xml
<dependency>
<groupId>org.slf4j</groupId>
<artifactId>slf4j-log4j12</artifactId>
<version>1.4.2</version>
</dependency>
2) Add the one Listner class in web.xml
<listener>
<listener-class>org.springframework.web.util.Log4jConfigListener</listener-class>
</listener>
3) Then add log4jConfigLocation in web.xml
<context-param>
<param-name>log4jConfigLocation</param-name>
<param-value>/WEB-INF/classes/log4j.properties</param-value>
</context-param>
and then add your log4j properties as follows :
# Direct log messages to a log file
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.File=C:\\loging.log
log4j.appender.file.MaxFileSize=1MB
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{ABSOLUTE} %5p %c{1}:%L - %m%n
# Direct log messages to stdout
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{ABSOLUTE} %5p %c{1}:%L - %m%n
# Root logger option
log4j.rootLogger=debug, file, stdout
4) Go to the particular java file in your application import log4j package
and then implement your logging mechanism
5) Now you should be able to trace the log

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 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 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 have a simple maven project and trying to get log4j implemented.
deploying to local tomcat. Nothing printing in console of eclipse where I have logger.debug().
Am I missing something?
This is my structure:
pom.xml:
<!-- http://mvnrepository.com/artifact/log4j/log4j -->
<dependency>
<groupId>log4j</groupId>
<artifactId>log4j</artifactId>
<version>1.2.17</version>
</dependency>
Class:
final static Logger logger = Logger.getLogger(myclass.class);
.properties file
# Root logger option
log4j.rootLogger=INFO, stdout
log4j.rootLogger=DEBUG, stdout
log4j.rootLogger=ERROR, stdout
# Direct log messages to stdout
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
Simply remove the superfluous rootLogger declarations:
# Root logger option
log4j.rootLogger=DEBUG, stdout
# Direct log messages to stdout
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
Logging levels are inclusive of those levels "above" them. For example, setting the logging level to DEBUG will include DEBUG, INFO, WARN, ERROR, and FATAL messages automatically. There is no need to declare logging levels for each one.
I used log4j for logging in my web application which is deployed using Tomcat on Amazon Cloud.
I can see the output of log4j on catalena. But, log file is not being created in the given location "/home/ec2-user/EmailLog/userdetails.log" and no logging is being done.
The same web application is running fine and creating the file and logging when tried on localhost.
My log4j.properties content:
# 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=/home/ec2-user/EmailLog/userdetails.log
log4j.appender.file.MaxFileSize=15MB
log4j.appender.file.MaxBackupIndex=1
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %-5p %c:%L - %m%n
# Direct log messages to stdout
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:%L - %m%n
And I instantiated the Logger by:
private static final Logger logger = Logger.getLogger(DBManager.class);
Please, suggest modification to make it work on Tomcat-Amazon.
