Is it possible to use JRuby (or other JVM-based scripting languages) to run scripts against RTC, using its Java client API?  Are there any examples showing how?

Yes.  I've started a wiki topic for this: https://jazz.net/wiki/bin/view/Main/JRubyScripting

"JRuby is an implementation of the Ruby programming language (and libraries), running on top of the Java runtime. It also makes it easy to call existing Java code, in a way that's idiomatic to Ruby. As an interpreted, dynamically typed language, it's easy to try things out and to iterate quickly, with quite concise code."


The examples there are Build-centric at the moment, but the same approach could be used for scripting other components in RTC / Jazz Foundation.

A similar approach could be taken with other JVM-based scripting languages, e.g. Groovy, Jython.
I'm considering switching these scripts to Groovy, since it's more "native" / common in the Java world (even though I personally quite like [J]Ruby).

I gave a lightning talk on this at Innovate 2013.  The BuildEnginesAndDefinitions.rb script is a slightly tweaked version of the one I walked through then.
