We are prototyping this in JRuby as a single .war file using warble. The HTTP server is…

JRuby, Torquebox, and Rails presentation from GR DevDay 2011

By Matt Fletcher | Published: November 7, 2011

This weekend I gave a talk at GR DevDay 2011 titled JRuby, Torquebox, and Rails. Overall it went well – plenty of practice meant I got the timing just right. I’m sure the walls in my kitchen are thankful they don’t need to listen to motivations for JRuby anymore. The talk was largely a reprise…

Pry yourself away from IRB

By Shawn Anderson | Published: September 16, 2011

.gist-meta {display: none;} For the past couple of weeks I’ve switched to using pry as my rails console / IRB replacement. I am loving it so far.

Be aware of jruby.launch.inproc

By Matt Fletcher | Published: July 5, 2011

Heads up for those not aware: it’s not hard to get burned when you’re executing other Ruby processes from within a JRuby process. Suppose you satisfy these conditions: You’re running a Ruby program via JRuby. Your program needs to execute another program via something like system or backticks. The command for the new program looks…

Bundle Your Torquebox Gems for Production

By Micah Alles | Published: April 28, 2011

We recently decided to try Torquebox for a JRuby on Rails app we’re working on. We chose Torquebox for the same reason we chose JRuby: reduce external platform dependencies to maximize ease of deployment in heterogeneous environments. Getting it up and running in development was pretty straight forward. However, when we tried to get a…
