I'm a Java programmer trying for the first time to use JRuby with
eclipse.


I downloaded the .exe file of the latest JRuby, and Java DLTK - Ruby
Development Tools. I installed both of them.
Than I set Ruby's interpreter in eclipse to jruby.bat, and the engine
debugger to be Ruby Built-In Debugger.


I wrote a simple Ruby code which compiled neatly and afterwards added:
require 'java'


I get an error message:

C:/Ruby21-x64/lib/ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in
`require': cannot load such file -- java (LoadError)
  from
C:/Ruby21-x64/lib/ruby/2.1.0/rubygems/core_ext/kernel_require.rb:55:in
`require'
  from C:/Users/eternalStudent/workspace/LetsTryRuby/HelloWorld.rb:1:in
`<main>'
