我从这里下载了文件 SwingSet3.jnlp：java.net/.../SwingSet3.jnlp。我正在运行 Windows 7 64 位操作系统，每次单击文件时，java 7都会启动，但随后会出现以下错误：无法启动应用程序。
这是例外：

在另一个选项卡中，我得到了这个例外：

这不是唯一的问题，当我访问这样的网站时：Game Of Life 我得到一个异常：ClassNotFoundException
也许有人知道是什么问题。
现在我在尝试打开文件时遇到了一些其他异常：

我尝试了很多不同的东西。我禁用了我的防火墙、avira 和 Windows Defender（这个已经被禁用了）。我也这样做了：netsh advfirewall set global StatefulFTP disable
但我也为一些 FTP 问题从 Windows 安装了一个修补程序（在此处输入链接描述），在此处输入链接描述。我还为我的互联网连接禁用了 IPV6。
从设置中的控制面板-> Java 控制面板中，我删除了跟踪和日志文件以及缓存的应用程序。我还取消选中该框以在我的计算机上保留临时文件。
Java 控制面板中唯一剩下的就是更改互联网设置，我可以将其设置为 Use ProxyServer，但我不知道我应该在里面输入什么地址或端口号。
有趣的是 Eclipse 运行良好！
我真的不知道接下来我应该做什么。似乎也没有人知道如何解决问题。
什么都没做，我只是将我的 Windows 从 Windows 7 家庭版升级到专业版，现在问题已经消失了。
