Question

最新的JRE（1.7.0_25）更新后，我的应用程序将不会像以前那样从webstart启动。我没有部署任何较新的jar文件或更改了Web服务器上的JNLP文件，但我无法从webstart启动该应用程序。它可以从IDE运行，也可以从本地jar执行

运行

我尝试在控制面板的高级选项卡中禁用所有证书检查等，但错误仍然存在，我不确定这是否与最新JRE中的新安全设置有关，或者是否有其他更改（可能是在Web服务器上？）我不控制Web服务器我只有一个发布应用程序的页面，并且可以访问jar文件的驱动器位置，权限对于驱动器位置是正确的等等。我现在丢失了至于问题是什么！我试着辞去罐子并验证签名

我感谢民间所能给予的任何帮助！完整错误如下：

Answer 1

即使您在显示jar signing所示的jar后，您也无法在浏览器中运行您的applet。完成签名后，您应该使用policytool.exe为活动jdk / jre的java.polcy中的类sun.security.ec.SunEC添加访问权限。确保以管理员身份运行policytool.exe，以便允许您修改java.policy文件。你必须为grant codeBase添加一个条目“file：$ {{java.ext.dirs}} / *”{permission java.security.AllPermission; };正如Matt C.所建议的那样。

java.lang.NoClassDefFoundError：无法初始化类sun.security.ec.SunEC（在最近的JRE更新后发生）
