I tried to import a jar as explained on the wiki page: https://github.com/jruby/jruby/wiki/CallingJavaFromJRuby but failed:

require 'java'
require 'jars/commons-lang3-3.4.jar'

include_class org.apache.commons.lang3.StringUtils
...

When running a ruby file from the console, it gives the below error:

C:\Users\XXXXX\Documents\projects\ruby_drafts\lib>jruby draft.rb
LoadError: no such file to load -- jars/commons-lang3-3.4
  require at org/jruby/RubyKernel.java:939
  require at C:/jruby-9.0.1.0/lib/ruby/stdlib/rubygems/core_ext/kernel_require.rb:54
    <top> at draft.rb:2

As you see, the ruby script is in lib folder, the jar to load is in lib/jarsfolder.

Reproduced on a Windows 7 PC, JRuby version:

jruby 9.0.1.0 (2.2.2) 2015-09-02 583f336 Java HotSpot(TM) 64-Bit Server VM 24.79-b02 on 1.7.0_79-b15 +jit [Windows 7-amd64]

Any idea ? Thank you.

the current directory is not automatically (anymore) on the $LOAD_PATH. you have to add it yourself:

jruby -I. draft.rb

Does it concern Windows only ? Because I have no problems with the same script on OS X.

does help on windows ?

the current directory could be on the classpath on OS X and not on windows. not sure how to check this.
