Log4j with HTML output

LOG4j is a simple and flexible logging framework. While developing any framework logging is must needed to track all the events at runtime and this will help further testers to debug the application logs and take some valuable decision's.

The most common configuration options are in practice industry wide i.e. using  log4j.properties configuration.

This this post, I am showing the example code for configuring log4j using log4j.properties file with HTML output

Step 1 : Download the log4j JAR : http://www.apache.org/dyn/closer.cgi/logging/log4j/1.2.17/log4j-1.2.17.zip   Click on zip link and store in your local disk, and later unzip the same. 

Step 2 : In eclipse create a new project(as log4jDemo) and with package com.log and also make sure that point the log4j.jar in class path

Step 3 : Create log4jhtml.properties file as show : make sure this is under src folder 

# Define the root logger with file appender

log4j.rootLogger = DEBUG, HTML

# Define the file appender

log4j.appender.HTML=org.apache.log4j.FileAppender

log4j.appender.HTML.File=/youtprojectpath/src/com/log/application.html

# Define the html layout for file appender

log4j.appender.HTML.layout=org.apache.log4j.HTMLLayout

log4j.appender.HTML.layout.Title=Application logs

log4j.appender.HTML.layout.LocationInfo=true

log4j.appender.HTML.Threshold=DEBUG

Please see the snapshot for the same 

Step 4 : Create a simple class called Log4jHTML under com.log package 

}

Step 5 : Right click and run the Log4jHTML.class  file 

Step 6 : Should create a html file  called Application.html as path set in the log4j properties file and output would look like this.Application.html

Thanks

Happy logging
