Logger.IsDebugEnabled() always return false

log4j

i am new to log4j and i have the following log4j.properties file in my java application
i am working on this in websphere 6.1

log4j.properties file

log4j.rootLogger=info, console

log4j.appender.console=org.apache.log4j.ConsoleAppender
log4j.appender.console.layout=org.apache.log4j.PatternLayout

log4j.package_name=debug

However this is working if i am using only one project as part of my application.If there are multiple projects and i want to use logging facility,logger.isDebugEnabled() always return false.. can anybody suggest a solution for this?

Thanks in advance

Websphere use a classloader for default for each EAR. If you have several Web modules or EJB modules and several files for log4j, only one is loaded by the classloader.

See A Powerful, Easy-to-Use Logging System for configure log4j with several projects in a EAR.

# Set root logger level to INFO and appender to STDOUT.
log4j.rootLogger=INFO, STDOUT

#------------------------------------STDOUT-----------------------------------#
# STDOUT is set to be a ConsoleAppender.
log4j.appender.STDOUT=org.apache.log4j.ConsoleAppender

# STDOUT uses PatternLayout.
log4j.appender.STDOUT.layout=org.apache.log4j.PatternLayout
log4j.appender.STDOUT.layout.ConversionPattern=%d %-5p (%c.java:%L).%M - %m%n

log4j.appender.STDOUT.Encoding=UTF-8

#-----------------------------------------------------------------------------#

# Specify the logging level for loggers from other libraries

log4j.logger.org.apache.commons.beanutils.BeanUtils=DEBUG

log4j.logger.org.apache.struts.action=DEBUG

log4j.logger.org.apache.struts.tiles=DEBUG

log4j.logger.org.apache.struts.util.ModuleUtils=DEBUG
log4j.logger.org.apache.struts.util.RequestUtils=DEBUG
log4j.logger.org.apache.struts.util.PropertyMessageResources=ERROR

log4j.logger.com.ibm._jsp=DEBUG

May you are missing the log4j.logger. prefix for each particular package.

Java – log4j’s configuration

Your configuration file isn't properly written.
Appender shouldn't be the class/package deceleration but a type of appender you would like to output messages to (leave it blank if you wish to output to the default appender)
The file should look more like:

log4j.rootLogger=FATAL 
log4j.logger.com.A=DEBUG

Java – log4j.properties configuration

Try assignining root logger as FATAL and divert the log to a dummy file :

    log4j.rootLogger=FATAL, fatalFile
    log4j.appender.fatalFile=org.apache.log4j.RollingFileAppender
    log4j.appender.fatalFile.file=log/fatal.log
    log4j.appender.fatalFile.MaxFileSize=10MB
    log4j.appender.fatalFile.MaxBackupIndex=10
    log4j.appender.fatalFile.layout=org.apache.log4j.PatternLayout
    log4j.appender.fatalFile.layout.conversionPattern=%d{[dd.MM.yyyy] [HH:mm:ss]} %p [%t] %c (%F:%L) - %m%n

and add console appender in log4j.logger.infoNTS as:

log4j.logger.infoNTS=DEBUG, file, nConsole
log4j.appender.file=org.apache.log4j.RollingFileAppender
log4j.appender.file.file=log/spider.cisco.log
log4j.appender.file.MaxFileSize=1GB
log4j.appender.file.MaxBackupIndex=10
log4j.appender.file.layout=org.apache.log4j.PatternLayout
log4j.appender.file.layout.conversionPattern=%d{[dd.MM.yyyy] [HH:mm:ss]} %p [%t] %c (%F:%L) - %m%n

log4j.appender.nConsole= org.apache.log4j.ConsoleAppender
log4j.appender.nConsole.target=System.out
log4j.appender.nConsole.layout = org.apache.log4j.PatternLayout
log4j.appender.nConsole.layout.ConversionPattern = %d{[dd.MM.yyyy] [HH:mm:ss]} %p [%t] %c (%F:%L) - %m%n
