我有一个使用来自MicroFocus公司的公共API的应用程序。我目前不打算在API上做太多事情，更简单的是使用X.509身份验证向网站进行身份验证。
我正在Eclipse Mars.2版本（4.5.2）中构建应用程序，并针对Java JRE 1.8执行该应用程序。
我希望我能提供代码，但是我被告知了它的专有性，但是目前，当我启动应用程序时，它连接到服务器，提示我进行X.509认证并返回会话。
当尝试完成身份验证部分时，我在Eclipe中收到以下错误消息：

我们已要求提供SDK的公司提供帮助，这就是他们所说的。
我相信异常错误与参数无关，而是由此SDK Java应用程序使用的类路径中缺少某些内容引起的。
我不是计算机的管理员，无法设置CLASSPATH环境变量，但被告知有一种方法可以通过Eclipse完成。
