introduction to jruby
DESCRIPTION
jRuby allows a developer to run Ruby applications in a Java Virtual Machine. Adam Kalsey from Tropo explains why you'd want to do that, what jRuby can do for you, and show how Tropo uses jRuby in building a real-time communications cloud service. Includes how to deploy apps on jRuby, and some of the pitfalls to watch out for.TRANSCRIPT
