HtmlUnit-PKIX路径生成失败：找不到请求目标的有效证书路径

Question

我在Glassfish上有一个使用GoDaddy SSL证书的JAVA EE webapp。HTTP侦听器重定向到HTTPS侦听器。

我正在尝试让HtmlUnit从Googlebot爬虫的网络应用程序中获取页面。该代码在未启用SSL的暂存服务器上按预期工作。但是，在具有GoDaddy SSL证书的实时服务器上，当HtmlUnit尝试获取网页时，我会收到以下错误。

我已经尝试了这里指定的解决方法(http://www.mkyong.com/webservices/jax-ws/suncertpathbuilderexception-unable-to-find-valid-certification-path-to-requested-target/)，但这没有帮助。你知道我为什么会犯这个错误吗？

解决方法是只在请求的页面上禁用SSL。当然，情况不一样，但这些废话太令人讨厌了。要禁用SSL，请在webClient对象上使用以下命令：

 webClient.getOptions().setUseInsecureSSL(true);
