LOAD_PATH

org.jruby.rack.RackInitializationException: no such file to load -- ...

Do not assume a lib (or any other folder) being on the $LOAD_PATH - make sure its properly added or use require_relative or absolute require File.expand_path ....

# config.ru
require './lib/myapp.rb'

# lib/myapp.rb
require 'myapp/helpers' # won't work
require_relative 'myapp/helpers' # or
# $LOAD_PATH << File.expand_path('lib')
