Hi
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.
Class with class method
# To change this template, choose Tools | Templates
# and open the template in the editor.
require "log4r/logger"
class XELogger < Log4r::Logger
def XELogger.get(fullname)
begin
return self.superclass.get(fullname)
rescue NameError
return Log4r::Logger.new(fullname , nil , true , false)
end
end
end
