求教大神如何解决运行selenium webdriver的程序时7054端口如何解决

Amamiyuki

自学基于Java的webdriver 照着网上找的一些入门教程写了一段简短的代码，但运行时发生异常，求教各位大神如何解决此问题。

代码为：
package org.coderinfo.demo;

import org.openqa.selenium.WebDriver;
import org.openqa.selenium.firefox.FirefoxDriver;

public class TestEnv {
        public static void main(String[] args)  {
                System.setProperty("webdriver.firefox.bin", "D:\\Program Files\\Mozilla Firefox\\firefox.exe" );
                WebDriver driver = new FirefoxDriver();       
                driver.get("http://www.baidu.com");
                System.out.println("page title is:"+driver.getTitle());       
        }
}


报错信息为：
