Use Log4J in wsadmin and Jython

We all love Log4j and I was really surprised to find how easy it is to use it from within your jython script and wsadmin. The log4j related classes are loaded with wsadmin (as part of its own classpath ) so you need no jars to be configured. Just use the following line of code to import the classes you need and start logging:

from org.apache.log4j import Logger
from org.apache.log4j import PropertyConfigurator
# change the path to your properties file
PropertyConfigurator.configure("log4j.properties") 
logger = Logger.getLogger("YourClassName")
logger.info("statement")

You can do everything you are used doing with log4j and this is just a simple example. An example property file will look like:

#Author Abhijeet Kumar
#Version 1.0
#FileName:log4j.properties
#Root Loggers
log4j.rootLogger=debug, stdout, R
#------------------------------------------------------------------------------
#
#  The following properties configure the console (stdout) appender.
#  See http://logging.apache.org/log4j/docs/api/index.html for details.
#
#------------------------------------------------------------------------------
log4j.appender.stdout=org.apache.log4j.ConsoleAppender
log4j.appender.stdout.layout=org.apache.log4j.PatternLayout
log4j.appender.stdout.layout.ConversionPattern=%d{yyyy-MM-dd HH:mm:ss} %c{1} [%p] %m%n
# Pattern to output the caller's file name and line number.
#------------------------------------------------------------------------------
#
#  The following properties configure the Rolling File appender.
#  See http://logging.apache.org/log4j/docs/api/index.html for details.
#
#------------------------------------------------------------------------------
log4j.appender.R = org.apache.log4j.RollingFileAppender
log4j.appender.R.File = /usr/logs/ApplicationDeployment.log
log4j.appender.R.MaxFileSize = 1000KB
log4j.appender.R.Append = true
log4j.appender.R.layout = org.apache.log4j.PatternLayout
log4j.appender.R.layout.ConversionPattern = %d{yyyy-MM-dd HH:mm:ss} %c{1} [%p] %m%n
