解决使用Selenium2进行Web自动化测试时IE启动失败的方法

我的机器环境是WIN7，IE8，JDK1.5.0，Selenium2.19.0版本，在调试WEB自动化测试过程中，遇到Firfox启动正常，但是IE8却启动报如下的错误：

 找了一圈的Google，有些是说要去掉浏览器的安全模式选择，但是发现没有用。

于是对代码进行了修改如下：

 DesiredCapabilities ieCapabilities = DesiredCapabilities.internetExplorer();
            ieCapabilities.setCapability

                    (InternetExplorerDriver.INTRODUCE_FLAKINESS_BY_IGNORING_SECURITY_DOMAINS,true);
            driver = new InternetExplorerDriver(ieCapabilities);
