共分三步：

1.selenium官网下载selenium-server-standalone.jar的最新版本号

2.启动selenium-server:::::
java
-jar "selenium-server-standalone-2.2.0.jar"

-Dwebdriver.firefox.bin="C:\FirefoxCollection\Mozilla
Firefox 36.0\firefox.exe"

3.java代码初始化webdriver对象时：

DesiredCapabilities
capabilities = new DesiredCapabilities("firefox", "", Platform.ANY);

driver=new RemoteWebDriver(new URL("http://127.0.0.1:4444/wd/hub/"),capabilities);

Ps:假设是调用本地的浏览器的话，

System.setProperty("webdriver.firefox.bin",
"F:\\InstalledFiles\\firefox\\firefox.exe");

WebDriver
driver = new FirefoxDriver(); 就可以
