Hey Sumit, most probably you are missing something in your configuration file. Make sure there is no misspelling in the ‘log4j.properties’ file name, that it is located in the default package, etc..
Download and check the linked NetBeans project (at the end of the post), it should work as-is.

I tried this code and followed the steps mentioned.. Although i am able to print my log message on the console, but nothing goes into the .log file.
