How to Get data from JSON request in struts2

I'm trying to get data from a JSON request in Apache Struts 2.
I've tested with this url: http://ift.tt/1lseVxE.
In StrutsJsonClientAction.java file, line

System.out.println(result);

prints this to the console:

{ "time": "12:04:12 PM", "milliseconds_since_epoch": 1431086652240, "date": "05-08-2015"}

I want to know how to show this result in result.jsp

Today, I found there is resttemplate can use in spring,I want to know are there the tools like restemplate in struts2 that I can use??

My current solution: StrutsJsonClientAction.java

package com.example.action;

import java.io.BufferedReader;
import java.io.InputStreamReader;
import java.net.HttpURLConnection;
import java.net.URL;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts2.ServletActionContext;
import com.opensymphony.xwork2.ActionSupport;
import javax.servlet.http.HttpServletRequest;
import org.apache.struts2.ServletActionContext;

public class StrutsJsonClientAction extends ActionSupport{

    private static final long serialVersionUID = 1L;

    private final String url="http://ift.tt/1lseVxE";

    public String execute() throws Exception {

        HttpServletRequest request= ServletActionContext.getRequest();

        request.setCharacterEncoding("utf-8");

        URL myUrl = new URL(url);
        //System.out.println(myUrl.toString());
        HttpURLConnection connection = (HttpURLConnection) myUrl.openConnection(); 
        connection.connect();

        BufferedReader reader = new BufferedReader(new InputStreamReader(connection.getInputStream(),"utf-8")); 
        String result=""; 
        String temp=null;

        while ((temp=reader.readLine())!= null) { 
            result=result+temp;
        } 

        System.out.println(result);

        return SUCCESS;
    }

}
