htmlunit驱动程序给我com.gargoylesoftware.htmlunit.html.HtmlPage无法转换为com.gargoylesoftware.htmlunit.InteractivePage错误

请在此处找到我的代码段，并且我在linux中使用rhel框:

Please find my code snippet here and I am using rhel box in linux:

WebDriver driver = new HtmlUnitDriver();
driver.get("https://www.amazon.com/ap/register?_encoding=UTF8&openid.assoc_handle=usflex&openid.claimed_id=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select&openid.identity=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0%2Fidentifier_select&openid.mode=checkid_setup&openid.ns=http%3A%2F%2Fspecs.openid.net%2Fauth%2F2.0&openid.ns.pape=http%3A%2F%2Fspecs.openid.net%2Fextensions%2Fpape%2F1.0&openid.pape.max_auth_age=0&openid.return_to=https%3A%2F%2Fwww.amazon.com%2Fgp%2Fyourstore%2Fhome%3Fie%3DUTF8%26ref_%3Dnav_newcust");
driver.findElement(By.id("ap_customer_name")).sendKeys("krish"); // line 24

我收到以下错误:

Exception in thread "main" java.lang.ClassCastException: com.gargoylesoftware.htmlunit.html.HtmlPage cannot be cast to com.gargoylesoftware.htmlunit.InteractivePage

    at org.openqa.selenium.htmlunit.HtmlUnitWebElement.sendKeys(HtmlUnitWebElement.java:330)
    at com.amazon.digitalmusic.UnitBrowser.main(UnitBrowser.java:24)

HTMLunit-2.17和Selenium jar文件在我的项目路径中.

HTMLunit-2.17 and selenium jar files are there in my project path.

我尝试了谷歌搜索，但无法解决.在这方面以及我出了问题的地方可以提供一些帮助.

I tried googling but could not be able to resolve it. Could some help in this and where I went wrong.

预先感谢
