ScriptEngine engine = new ScriptEngineManager().getEngineByName("nashorn");

try {
String path = BankTradeList.class.getResource("").getPath();
System.out.println(path);
//String path = "woori.js";
engine.eval(new FileReader(path + "woori.js")); 
Invocable invocable = (Invocable) engine; 
Object result = invocable.invokeFunction("wooriTrade", "1");
System.out.println(result);
