How can I call a Lua script from Java

Question

I want to run a Lua script from Java GUI. Can I develop it in a Java IDE. What I want to achieve:

I will have a button in Java that will run a Lua script.
Then the Lua script will run and return something that I can capture in my Java code and show it in the GUI of java.

I found a package, which helps in integration of Lua with Java.

Simple Application:

import org.luaj.vm2.*;
import org.luaj.vm2.lib.jse.*;

Globals globals = JsePlatform.standardGlobals();
LuaValue chunk = globals.loadfile("examples/lua/hello.lua");
chunk.call();

On doing chuck.call(), save the return value to a variable. See, if that helps.

@setubasak I am not sure about that, coz loadfile basically load lua file and is been executed by doing call().
