Re: [jruby-user] jruby inside jython

I think the problem is your jython code doesn't set the path to Ruby
scripts resides in test/unit directory. As for Java, setting a system
property, "com.sun.script.jruby.loadpath," before getting a instance
of JRuby's engine might resolve this kind of errors.

     String loadPath =
         "C:/temp/jpythonruby/jruby-1.0.2/lib/ruby/1.8";
     System.setProperty("com.sun.script.jruby.loadpath", loadPath);
     ScriptEngineManager manager = new ScriptEngineManager();
     ScriptEngine engine = manager.getEngineByName("jruby");

But, sorry, I don't know how to set a system property by jython.
