Forum: JRuby Who uses JRuby

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

Here are some orgs I'm aware of:

Danish Technological University - Library
University of Minnesota - Minnesota Population Center
Best Buy
GovDelivery
Tufts University - Digital Collections and Archives

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!

Interesting, do you know any details about the Best Buy deployment?

It's this product: https://bbyopen.com/developer

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.

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

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?

I believe Square use it quite a lot?

My company uses JRuby/SWT to write cross-platform desktop apps:

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 <http://www.logeek.fr> developed and still maintains 
a
group of Java CRM extensions for BMC
Remedy<http://www.bmc.com/products/product-listing/it-ser...
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.

[1] www.gov.uk

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

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

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!

I work on a jruby on rails application at IBM in the Big Data department 
and I know of another jruby on rails deployment in the Information 
Management department plus a bunch internal applications.

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.

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.

Hello,

We at Vinci Energies/Actemium  use JRuby in SCADA system for :
* coding web service : data in JSON, treatment in JRuby, data
  in memory(pojo) and Hibernate
* macro language : use JRuby for synoptics (animations, command
  interpret) server side, SVG/javascript  client side
* gateway for protocol adapter (when data flow com from serial line
  protocol)

Scripting install/run/stop/redundant (Oups, ruby 1.9 for that)

This SCADA base is use in transport systeme, video supervisor, gateway.

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! :)

-Darshan.
