Subject: I suspect syntax got me this time

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
