[jruby-dev] Exception in thread "main" java.lang.NoSuchMethodError: org.jruby.Ruby.newInstance()Lorg/jruby/Ruby;

Hi 

I am trying to JSR223 to call ruby method from java. 

My Jruby version is 0.9.8. My Java Version 6.

 

Here is my Code

import javax.script.*;

import java.util.*;

 

public class EvalScript {

    public static void main(String[] args) throws Exception {

     ScriptEngineManager mgr = new ScriptEngineManager();

      // Create a JRuby engine.

      ScriptEngine engine = mgr.getEngineByName("jruby");

      // Evaluate JRuby code from string.

      try {

        engine.eval("puts('Hello')");

      } catch (ScriptException exception) {

        exception.printStackTrace();

      }

    }

}

 

When I try to run this application, I am getting the following error:

Exception in thread "main" java.lang.NoSuchMethodError:
org.jruby.Ruby.newInstance()Lorg/jruby/Ruby;
