ScriptEngineManager manager = new ScriptEngineManager();
ScriptEngine engine = manager.getEngineByName("lua");
List testList = new ArrayList();
engine.put("age", 21);
engine.put("testList", testList);
Object i = engine.eval("sys = luajava.bindClass(\"java.lang.System\") "
+"sys.out:println( sys:currentTimeMillis() ) "
+ "if (age >= 22) then "
+ "    sys.out:println('Old enough to vote!') "
+ " else "
+ "    sys.out:println ('Back to school!')"
+ "end"
+ " testList:add (\"in list\") ");
 
System.out.println(testList.get(0));
