I'm trying to access a local HTML page that contains a Java applet on my Windows machine with Firefox. I'm aware of the security implications, so I don't need a lecture about that. The page is from a trusted source...

The problem is that the Java Control Panel only allows "Very High" or "High Security," and does not allow file references in the Exception Site List. Does anybody know how am I supposed to get Java Applets to work locally?

This question came from our site for power users of web applications.

  • If it's a local file anyhow, why not just run it as a Java application instead of embedding it in an HTML file? Also, the schema for a file: URI is basically just file://; they don't usually have host/domain names (the way HTTP/HTTPS URIs do) and the third slash is the path separator; you can add it but it shouldn't be needed here (nor anything after it, like the C:, unless you're going to supply the full path to your file). – CBHacking Feb 9 '17 at 1:58
  • Also, does it need to be Firefox? I think IE's applet security rules are a little more flexible, though you'll need to change the defaults to make it work on local files with IE, too. – CBHacking Feb 9 '17 at 1:59
