Some time the need arises to have our log4j.properties with different name. By default, if no other configuration is given, log4j will search your classpath for a 'log4j.properties' file.

Now to use your own named log4j property add the following line in your main program:

  PropertyConfigurator.configure("File  name with path")

exmaple:

 PropertyConfigurator.configure("c:\\logs\\my-log4j.properties")   this will set this as a default property name and all done =)

This is a very common problem, it occurs when log4j.properties not found in classpath.

Create a file called log4j.properties. Place it in the root folder where your java classes are found. When log4j initializes, it will look for a file named EXACTLY log4j.properties (if you are using a properties file).

Another alternate way is to put the path to the log4j.properties file in your classpath.

Hope this will help you :)
