jruby-rack | Rack for JRuby and Java appservers | Continuous Deployment library

I am trying to start the sonarqube with ./sonar.sh start command. It starts for 5 secs and then stops on it own.

The log file shows this:

We recently upgraded an old rails app from rails 3 to 4.2, along with many other gem updates. Now I can't get my rails app to load any pages. We were on JRuby 9.1.0.0 but upgraded to 9.1.8.0. However, I'm hitting the same problem on both versions.

Once we start tomcat with our latest .war, it runs all the way until I see the INFO: Server startup in 1234ms message. I've added some debug statements in my rails environment / initializers files to follow it through and it is hitting each of them. So once I see the startup message from tomcat, I figured it would be okay. However, it immediately spits out the following message quite a few times:

DEBUG: resetting rack response due exception

Every time I load a URL, it also shows that message in my logs.

I see that it's from this jruby-rack class but I have no idea how to debug or troubleshoot this further.

I assume that something in my configuration is causing a problem or that a class/module is somehow short-circuiting it but I'm not sure how to identify which one it is or isolate the issue.

Does anybody know of a way to get some more verbose logs or ways to figure out where the problem is happening?

Happy to post any config/gemfiles etc if it will help.

I have a Jruby project that is using background processes that need to be run every x minutes. I am using Jruby-rack-worker + delayed_cron_job library. I have followed the jruby-rack-worker instructions as follow:

1. Copy the jruby-rack-worker.jar file under lib folder

2. my web.xml located under config folder:

3. my worker rb file:

1. my GEM file:

   gem 'jruby-rack-worker', :platform => :jruby, :require => nil
   gem 'delayed_cron_job'

After the deployment of the WAR file on WebLogic, I have checked the log file and I can see that after the completion of deployment, It is trying to start the Worker but nothing happening:

We'd like to deploy multiple instances of the same Rails application within a single Tomcat container using jruby-rack.

The first instance comes up fine, but the second one fails:

I am trying to restore a quality profile on a fresh installation of SonarQube v.5.6.4 over Web API using curl.

In c:\temp I have an exported "Sonar way" profile from running Sonar and I have renamed it to test.xml (inside, the name was also changed to test so that both profiles are "different").

From the c:\temp location, I used the following curl command:

Steps to replicate:

1. Create a new Rails project. (rails 3.2.22.5)
2. Add dependencies (warbler, rake, rufus-scheduler) (/Gemfile)
3. JRuby 9.1.7.0
4. Create new files. (/config/warble.rb) (/web.xml.erb) (/config/intializers/scheduler_rufus.rb)
5. Create an executable war file with jetty webserver. (warble war RAILS_ENV=development)
6. Launch the executable. (java -jar mywar.war)
7. The scheduler does not run the cron job.
