Can't launch simple Sinatra app using rackup and jRuby (no response from web server)

Question

I\'ve got a Sinatra \"hello world\" app that I am trying to run using jRuby. It works when I run the app, but not when I run rackup. Can anyone tell me what is going on here?

Answer 1

#config.ru
require "./app.rb"

set :bind, '0.0.0.0'
set :port, 9292 #set your port!
Sinatra::Application.run!

try this code and type rackup

Then you can get the results you want.
