6 个解决方案

#1

I had this issue. The security settings in the ControlPanel seem to be user specific. Try running it as the user you are actually running your browser as (you are not browsing as root!??) and setting the security level to Medium there. - For me, that did it.

我有这个问题。ControlPanel中的安全设置似乎是特定于用户的。尝试以实际运行浏览器的用户的身份运行它(不是以root用户身份浏览)，并将安全性级别设置为中等。-对我来说，就是这样。

#2

As an alternative answer, there's a command line to invoke directly the Control Panel, which is javaws -viewer, should work for both openJDK and Oracle's JDK (thanks @Nasser for checking the availability in Oracle's JDK)

作为另一种解决方案，有一条命令行可以直接调用控制面板(即java aws -viewer)，它应该同时适用于openJDK和Oracle的JDK(感谢@Nasser检查Oracle的JDK中的可用性)。

Same caution to run as the user you need to access permissions with applies.

与需要访问权限的用户一样，要使用同样的警告。

#3

$pwd /usr/lib/jvm/jre1.8.0_25/bin

$ pwd /usr/lib/jvm/jre1.8.0_25 / bin

./jcontrol

。/ jcontrol

as follow,

遵循,

java Control Panel --> Security --> Edit Site list ,
then apply, and ok.

java Control Panel——> Security——>编辑站点列表，然后应用，ok。

#4

The application that you are running is blocked because the application does not comply with security guidelines implemented in Java 7 Update 51

您正在运行的应用程序被阻塞，因为应用程序不符合Java 7 Update 51中实现的安全指导原则

#5

You can also use Edit Site List and make it be an exception so that you can run it from the specific website.

您还可以使用编辑站点列表，并使它成为一个异常，以便您可以在特定的网站上运行它。

Just start your browser with superuser rights, and don't forget to set Java's JRE security to medium.

只要用超级用户权限启动浏览器，不要忘记将Java的JRE安全性设置为medium。
