You can download JRuby 1.1.2 separately from:

   http://dist.codehaus.org/jruby/

And then add it to the Platform Manager. Since then you can use it for
your projects.

By default Gems are installed into an interpreter's directory. To share
RubyGems between two interpreter you might set the same GEM_HOME (from
Ruby Platform manager) for e.g. JRuby 1.1.1 and JRuby 1.1.2.

See:

   http://rubygems.org/read/chapter/3#page83

for more details.

I discourage the use of NB 6.1 Beta. Use 6.1 final and be sure you have
applied all the patches:
