In GlassFish v3 I am using JRuby APIs to instantiate JRuby and Rails
runtime. I am using maven to write a unit test for rails. My maven
dependency is on jruby-complete.jar. However when my test tries to
loadup
the rails application I get the error
“Missing the Rails 2.1.0 gem. Please gem install -v=2.1.0 rails,
update
your RAILS_GEM_VERSION setting in config/environment.rb for the Rails
version you do have installed, or comment out RAILS_GEM_VERSION to use
the
latest version installed.”
This explains why, because jruby-complete.jar does not have Rails gem.
What
options do have to make it work so that JRuby runtime can locate Rails
gem
as resource from the classpath?I tried copy Rails gem as part of maven
test
resources but this does not help.
Anyone, any idea how I can make Rails gem or anyother gem available to
JRuby
runtime while using jruby-complete.jar?

Set the environment variable GEM_PATH to the location of a place where
you’ve pre-installed the Rails gem. Typically this will be something
like
GEM_PATH=/usr/local/jruby/lib/ruby/gems/1.8
Entries on GEM_PATH have cache, doc, gems, and specifications
directories.

Great! This works. Although I would have preferred a java system
property
but this would do.
thanks,

Well it would work in my standalone case, I can do export GEM_PATH=…
but
it does not help me when I try to automate. The unit test will be run
using
maven and there does not appear a way to set environment variables from
inside maven pom files:-(

Not ideal, but could you require/export GEM_PATH in ~/.mavenrc on the
build machine? You’d probably have to have the gems directory set up
ahead of time anyway, unless you plan to have the gem repository
checked in somewhere.
Otherwise you could use a java system property to pass the value along
and have a special path to handle setting GEM_PATH inside JRuby during
your test setup.
