如何使用jruby从Java运行需要Ruby库的Ruby（mcollective）

Question

I am trying to run the following ruby script.

require 'rubygems'
require 'mcollective' 

from following java code

ScriptingContainer ruby = new ScriptingContainer(LocalVariableBehavior.PERSISTENT);
        Object result = ruby.runScriptlet(PathType.ABSOLUTE,"/opt/ruby_test.rb");

But I am getting the following exception.

require at org/jruby/RubyKernel.java:1027
  require at jar:file:/tmp/target/dependency-jars/jruby-complete-1.7.3.jar!/META-INF/jruby.home/lib/ruby/shared/rubygems/custom_require.rb:36
   (root) at /opt/ruby_test.rb:3

Please help me to solve this.

我通过使用rvm安装mcollective-client ruby​​ gems解决了该问题。
