WebDirver截图报错，请前辈们指点下

ragpickerlee

使用WebDirver进行截图时报类型转换出错，困扰好几天了，请有经验的朋友帮忙指点下。

代码如下，运行完后有报错，D盘下也没有生成文件：
public void testTakesScreenshot() {  
        WebDriver driver = new InternetExplorerDriver();  
        driver.get("http://www.xxx.com");  
        try {  
            File scrFile = ((TakesScreenshot)driver).getScreenshotAs(OutputType.FILE);  
            FileUtils.copyFile(scrFile,new File("d:\\screenshot.png"));  
        } catch (Exception e) {  
            e.printStackTrace();  
        }   
        driver.close();  
}


报错信息如下：
