I have created a class with a class method. I am trying to call it
from a different class and I get the “uninitialized constant” error.
Could some body help me out.

Will configure log4r from the xml configure file passed
The file object can be just the name of the file if the
file is in the same folder, if otherwise file object
should be a complete path to file’s location.
ToDo: Needs Tesing.
