Question

I'm trying to run selenium webdriver program, getting following error : 我正在尝试运行Selenium Webdriver程序，出现以下错误：

Exception in thread "main" java.lang.NoSuchMethodError: org.openqa.selenium.io.FileHandler.unzip(Ljava/io/InputStream;)Ljava/io/File;

Firefox version : 47.0.1 Selenium version : 2.53.1 Eclipse : Oxygen Release (4.7.0) Firefox版本：47.0.1硒版本：2.53.1 Eclipse：氧气发行版（4.7.0）

import org.apache.xpath.XPathContext;
import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

    public class PG1 
    {
        public static void main(String[] args) 
        {
            WebDriver driver = new FirefoxDriver();
            driver.get("http://demo.guru99.com/selenium/newtours/");
            System.out.println("The title of page is : " + driver.getTitle());
            driver.close();
        }
    }

This program was working fine in another laptop, but not working on new laptop/setup. 该程序可以在另一台笔记本电脑上正常工作，但不能在新的笔记本电脑/设置上工作。

Can someone please help. 有人可以帮忙吗？

Answer 1

Found what was wrong.. it was that in "Java Build Path", the JRE system library was not added earlier. 发现问题所在。在“ Java Build Path”中，JRE系统库没有被添加。 I went to configure Build path-->Add Jars selected "jRE system library", Applied & Closed. 我去配置Build path-> Add Jars，选择“ jRE system library”，Applied＆Closed。

Then on all the programs worked fine. 然后，所有程序都运行良好。
