  config.jar_name = "jsinatra"
  config.webxml.booter = :rack
  config.webxml.jruby.compat.version = "1.9"
  config.webxml.rackup.path = '/WEB-INF/config.ru'
end

any help, advice apricciated. thank you.

over all, i am trying to create docker container and i am using pdf file as a reference but the pdf is somehow vaguely written. http://www.ibm.com/developerworks/cloud/library/cl-sinatra-softlayer-app/cl-sinatra-softlayer-app-pdf.pdf

Solution

  • Worked for me

    In the pdf I posted there is file named rackup.ru with this contents:

    require "sinatra"
require File.dirname(__FILE__) + '/app/main'
run MyApp

    After hours of googling, I decided to create identical file and name it config.ru. Worked.

    Not working

    I have also tried to change

    config.webxml.rackup.path = '/WEB-INF/config.ru'

    to

    config.webxml.rackup.path = '/WEB-INF/rackup.ru'

    Did not work.
