Java小程序涉及磁盘读取的应用程序安全警告
我有一个java小程序，当用户访问网页时，它会下载到用户的浏览器，并允许他们将可恢复的文件上传到我的服务器。显然，这需要小程序访问用户的硬盘，据我所知，这超出了小程序可以运行的常规沙箱范围。用户会看到一个安全警告弹出窗口，要求他们允许该小程序运行。
我已经使用 verisign 对小程序进行了签名，并且获取小程序的链接是通过 SSL 和经过验证的证书进行的。这些都不能消除警告。
有没有办法让所有警告消失？谁能解释一下幕后发生了什么？
I have a java applet that is downloaded to a user's browser when they visit a webpage and allows them resumable file uploads to my server. Obviously, this requires the applet to access the user's hard disk, which I understand is outside the regular sandbox applets can run in. The user sees a security warning popup which asks for their permission to allow this applet to run.
I have signed the applet using verisign and the link from where is applet is fetched is over SSL with a versigned cert. None of these make the warning go away.
Is there a way to make all warnings go away? Can anyone explain what is going on behind the scenes?

JNLP 有一个 FileOpenService，它允许不受信任的 Java Webstart 应用程序向用户显示“文件打开”对话框并访问用户选择的文件：

您无法避免此消息，如果可以的话，这将是一个安全问题。
您可以做的是进行配置（策略文件）以允许该小程序使用某些文件。但您必须手动执行此操作（出于明显的安全原因）。检查下面的链接。

You can't avoid this message, it would be a security issue if you could.
What you can do is having a configuration (a policy file) to allow this applet to use some files. But you would have to do this manually (for obvious security reasons). Check the link below.
