[jruby-user] Who uses JRuby

[jr...@smallruby.com]

Hi, I'm preparing a presentation to make a case for JRuby. I hope to
find some list of companies that use it. The more enterprise level the
list the better since that's the main space we deal with.

I was not able to find such a list or much PR related content on
jruby.org.

thanks in advance

-Charles

We, Datek Wireless in Norway, use JRuby for two critical systems at Oslo Airport Gardermoen: Fleet control of the passenger busses and fuel trucks.

So there! Write a wiki page! https://github.com/jruby/jruby/wiki/SuccessStories

My company, Burt (burtcorp.com), processes a couple of billion messages or around a terabyte of raw data per day, using JRuby.

We currently use JRuby for the first time in one bigger project (can't give you specific details, but in essential a big database coupled with a SOLR search in conjunction with 2 other administrative applications. The main application is split into multiple rails applications, which is in itself quite interesting. So far the experience has been quite good, although I would not recommend the Tomcat/JRuby combination for beginners (caused a headache or two). Also, i had some problems with encoding in 1.6.x when parsing CSV data, although this now works nicely when using 1.7.0.

[Florian Kraft]

I should probably mention that my company is http://www.ewerk.com and is a service provider.

[Samer Abukheit]

At On-Site (www.on-site.com), after many years of Java, we're now using JRuby, and doing everything in JRuby/Rails. When we need to, we sometimes use old business logic from java land, after testing it with JRuby.

Was the problem with tomcat or jruby? If tomcat is the problem what do you suggest as an alternative?

[James Abley]

I believe Square use it quite a lot?

The problem is that we encountered some problems with rails needing root context for proper execution (this is not a jruby problem), as the routes get messed up. This is partly due to my inexperience with tomcat itself, i haven't really used it before :-) I can't really suggest alternatives in production, as i have not tried any yet - i am still fairly new to the whole jruby experience. I can post an update when the application goes live and i have gained more experience with the whole process in production

Hi,

> I hope to find some list of companies that use it. The more enterprise level the list the better since that's the main space we deal with.

My (small) company developed and still maintains a group of Java CRM extensions for BMC Remedy in JRuby, in a fairly enterprisey environment (call-center subsidiary of a french insurance company, so fairly far away from startups).

It's a small scale system (handling =~10k Resque jobs per day, generating PDF documents, creating/updating tasks in the CRM via the API, statistics etc), but it showed me that using JRuby for "enterprise glue" works great, and is a place where JRuby definitely shines (good testing quality, concise code, ability to leverage both ruby and java libraries etc).

hope this helps,

We're [1] using logstash for log collection from both Ruby and Scala apps.

I hope to have some more JRuby-related news our stack in a couple of months.

[Mark Thomas]

The Bureau of Labor Statistics (www.bls.gov) uses JRuby in production on
several Rails apps. Some are externally facing, and others are internal.

[Kimberley Scott]

Hmm.

I use JRuby but mainly for cmd line apps on multiple 16/32 core boxes with 32Gb+ RAM and 100Tb+ plus file systems.

(I'm a dinosaur from the 70's before we had graphics - I live at the command line :-)

Currently have record label reports going through a large number of cronned jobs that use ActiveRecord in a Rails project with no front end (yet).

These thrash the daylights out of a dozen databases on a load of boxes with oodles of tables and 100s of millions of rows and do a great job.

One table has 140+ million rows in it for example and JRuby chomps down and relishes it.

No dramas.

Ok. One. I had to add -J-Xmx2000m on one script due to legacy issues. But in general no dramas.

Real time ETA minutes instead of hours for the archaic, un-frickin-believably long and un-maintanable PHP scripts.

Managers are happy…

Scored a badass Ubuntu box free for home use based on latest results.

Sweet.

This is really an excellent thread, thank you all! We will need to
pull this into our Success Stories page on the wiki, which definitely
needs some refreshing.

Keep these stories coming!!! Tell your friends who use JRuby to tell
us their stories!

Duolog Technologies is happily using JRuby in its System On Chip (EDA) integration tools:

At Groupon we use MRI for a lot of our tooling / site, but I've setup some internal services using JRuby in the past 6 months. We definitely had teething pains setting it up (picking an app server, setting up a deploy, getting consoles/rake tasks do have a ruby env, JVM tuning, ...), but it's been working well after we ironed most of those out. I personally expect having access to the JVM ecosystem will be a huge asset long-term.

Thank you Charles and the rest of the JRuby team for all of the hard work you have done over the years to make JRuby so awesome.

I am an independent consultant that works in the Enterprise software
space and I use jruby for almost anything that I would have used perl,
awk or shell scripts for in the past. Since there is no requirements
other than Java I have been able to bring it into the environments I
work without issue.

It has been a huge help to me. 1+ for sure on the thank the jruby team
for all the tremendous work they have put into this.

my company nokaut.pl is using jruby + torquebox to process product feeds, deliver internal apis & inside customer apps.

Flexibility of including legacy java code is amazing. Not to mention speed improvements. I love it!

We at Tata Consultancy Services use JRuby (on Rails) in one of the
internal applications & it is running strong since past 1 and a half
years now.

Thank heavens that Charles & team invented JRuby! :)
