Hi All,

I made a mistake in my test code. It should be:

$ irb
irb(main):001:0> require 'rubygems'
=> true
irb(main):002:0> require_gem 'rails'
re=> true
irb(main):003:0> require_gem 'rjb'
=> true
irb(main):004:0> Rjb::import 'junit.framework.Assert'
=> #<Rjb::Junit_framework_Assert:0x2b25d052dac0>

cheers,
Rich
