Having issues getting a war file to run #487

I created a simple test Rails app with sqlite db and used warbler to create a compiled executable war file. I used java -server -jar app.war -S puma -p 3000 -c config/puma.rb to start the app. I also tried with -S rails s but no luck. It says either "config.ru not found" or "no application configured, nothing to run" or some other errors and exit system. Googling did not yield much, a few articles from 2012-14, and a couple recent but wasn't helpful.

Could you help guide on how to get create a compiled rails application? Let's start with:

  1. Is it better to create a runnable or executable war or jar file of the Rails app?
  2. Can I use puma as the jruby server or something else? I saw one article using puma.
  3. What do you recommend on how to handle filling in values for database.yml and other such configuration files when doing production deployments of the compiled war app? Env vars?
  4. How would I run rails db:setup and rails db:migrate to setup production databases using the compiled war app?
  5. Lastly is there any examples of a working rails production app that I can refer to on how they configure warbler to create war file and run?

Using Rails 6.0.3.4, latest JRuby 9.2.13 for simple test app but the target app will be rails 5.1.7.

Thank you in advance.

Could you show us the commands you used to build the war file?

It sounds like it is getting built but upon booting up it can't find the files inside the war. Perhaps the way those files get loaded no longer works in a jar/war form.

Sure. Thank you for your quick response. Really need to get this working soon.

I created warble.rb and set compiled runnable options. Every thing else is default values. I had issues with executable option trying to download jetty and failed with socketError to repo2.maven.org - name or service not known.

The sample rails app works when I run bundle exec rails s so I know the app is working with puma.

Let me know if there's anything else you require. The rails app is a simple test app with the default scaffold cars model, controller, view.

Same issue here, here's how I solved:

.rbenv/versions/jruby-9.3.2.0/lib/ruby/gems/shared/gems/warbler-2.0.5/lib/warbler/web_server.rb

Changed line 91 from this
@artifact = Artifact.new(ENV["MAVEN_REPO"] || "http://repo2.maven.org/maven2",
to this
@artifact = Artifact.new(ENV["MAVEN_REPO"] || "https://repo.maven.apache.org/maven2",

Thank you @daemonzone, this worked for me as well. Would be nice if you would open a pull request for that. 😉
