平，

在Windows 7-64位上将我的java版本从6u31更新到7u4后，applet停止工作。我使用java-32位，浏览器也是32位（尝试IE9和Firefox 12.0），唯一的原因是更新java。 我使用了来自http://www.java.com/en/download/testjava.jsp的测试，得到了这个结果：

我已经尝试了很多不同的选择，例如禁用防火墙，禁用Java控制面板上的下一代插件，清除缓存，卸载和重新安装（JRE和JDK），使用混合模式安全验证，也许还有一些我不记得了。 我不知道还有什么我可以尝试让它发挥作用..任何人经历过同样的事情并解决了它？

啊，作为公司政策，如果可能的话，我们必须坚持使用最新版本，因为安全性更新。

答案 0 :(得分：1)

好的，问题是我在使用java访问页面时连接了VPN（CISCO）。从Java 7开始，由于Ipv6（http://jonathangiles.net/blog/?p=1126）存在问题。所以我从VPN连接禁用它并将此行添加到java运行时参数： -Djava.net.preferIPv4Stack =真

现在它工作正常。
