Thanks a lot to Amit Hurvitz for providing a file of Virtual Disk Image (VDI) of VirtualBox, containing an up and running JRuby on Rails on Glassfish with Mysql. Image also contains some examples (actually solutions to the code camp exercises), all running on top of an OpenSolaris guest OS (can be run on many host systems).

Grab the image ~1.5GB archive.

Grab the exercises ~9.7MB archive.
