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

-Justin

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?

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.

The data mining and business intelligence system for the following sites
is
powered by JRuby. Over 500 million transactions processed.

http://www.couponcodes.com
http://www.dailydeals.com/

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?

Reuters finance news

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 :slight_smile: 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
Remedyhttp://www.bmc.com/products/product-listing/it-service-management-suite.htmlin
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,

– Thibaut

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.

My company uses JRuby/SWT to write cross-platform desktop apps:
http://fireapp.handlino.com/ and http://compass.handlino.com/

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!
