如何使用 Java 使用 Selenium 运行 ghostdriver

I want to use phantomJS for some web testing, and I've come across GhostDriver (https://github.com/detro/ghostdriver). I've built it using the instructions in the readme and I can run it on a specified port, but I am not sure how to access the web driver from my java code. To clarify, I've seen this example in ruby:

  caps = {
  :browserName => "phantomjs",
  :platform => "LINUX"
   }

urlhub = "http://key:secret@hub.testingbot.com:4444/wd/hub"

client = Selenium::WebDriver::Remote::Http::Default.new
client.timeout = 120

@webdriver = Selenium::WebDriver.for :remote, :url => urlhub, :desired_capabilities => caps, :http_client => client
@webdriver.navigate.to "http://www.google.com/"
puts @webdriver.title
@webdriver.save_screenshot("./screenshot.png")
@webdriver.quit

我只是不确定如何在 java 中做同样的事情.
