Question

Here i am trying to load my Jruby script into my java code but am getting long error that i realy don’t know what it means,

The player.rb file is in the same folder as the TEST.java is.

Here is the error am getting:

java.io.FileNotFoundException: .player.rb (The system cannot find the file specified)

Here is my Java code:

import org.jruby.*; 
import java.util.ArrayList;
import java.util.List;
import org.jruby.embed.PathType;
import org.jruby.embed.ScriptingContainer;

public class TEST {
    private final static String jrubyhome = "C:/jruby-1.6.3";
    private final String filename = "player.rb";

    private TEST() {
        ScriptingContainer container = new ScriptingContainer();
        List<String> loadPaths = new ArrayList();
        loadPaths.add(jrubyhome);
        // JRuby 1.5.x
        container.setLoadPaths(loadPaths);
        // JRuby 1.4.0
        //container.getProvider().setLoadPaths(loadPaths);
        container.runScriptlet(PathType.ABSOLUTE, filename);
    }

    public static void main(String[] args) {
        new TEST();
    }
}

And here is my Ruby code:

def numberMethod
  number = 3
return number
end

puts numberMethod
puts "Test, test!"

The new error i got now:

Answer 1

I guess the PathType.ABSOLUTE constant is the culprit. Change that (e.g. to PathType.RELATIVE) or provide the full path to your test.rb file.
