selenium2 测试 SSL HTTPS问题：报错

我用selenium2 测试 https网站，但是获取不到页面内容例如：

代码：

WebDriver driver = new InternetExplorerDriver();
driver.get("https://www.citi.net/confluence/display/159223/Cloud+Development");
WebElement element = driver.findElement(By.xpath("//input"));
element.sendKeys("asdfasdf");

结果报错：
