java.lang.SecurityException: Permission denied: file:////Videos/public/scripts/screenshot.jar当我尝试使用小程序时，我得到了。
这是小程序代码：
<applet code="Screenshot" archive="file:////Videos/public/scripts/screenshot.jar" width="100px" height="100px">
</applet>
我该如何解决它，问题甚至意味着什么？
编辑：
据我所知，我需要签署小程序。有人可以解释如何以及为什么这样做吗？提供的网站在解释它方面做得不好，因为它甚至没有解决我将它嵌入到我的网站中并希望每个客户都使用它而不必签署任何东西的事实。只需点击运行。

应用程序本身的代码：

// and now The inevidable "Hello World" example :)
// tell the compiler where to find the methods you will use.
// required when you create an applet
import java.applet.*;
// required to paint on screen
import java.awt.*;
// the start of an applet - HelloWorld will be the executable class
// Extends applet means that you will build the code on the standard Applet class
public class Screenshot extends Applet
{
// The method that will be automatically called when the applet is started
public void init()
{
// It is required but does not need anything.
}
// This method gets called when the applet is terminated
// That's when the user goes to another page or exits the browser.
public void stop()
{
// no actions needed here now.
}
// The standard method that you have to use to paint things on screen
// This overrides the empty Applet method, you can't called it "display" for example.
public void paint(Graphics g)

// String first, then x and y coordinate.
g.drawString("Hey hey hey",20,20);
g.drawString("Hellooow World",20,40);
}
