Code For OCR Scanner Not Working As Applet

I need to make a scanner (that has a built in ocr) output some content to a browser. I haven't gotten to the browser yet, but the code works when I run it as an application. With the scanner, I received Java code that makes the scanner take a picture, then read from it and output it back to the console. I added a few lines to make it an applet:

Java Code:

import gx.*;
import pr.*;
import java.applet.*;
public class DocScan extends Applet {
/**
*
*/
private static final long serialVersionUID = 1L;

[Code] .....

I am using Eclipse as an IDE. Right now my goal is to simply make the scanner "flash". I know that the output is to the console and I will not see anything from it in an applet, but it should still flash.

When I run this code as an application, it works. The scanner takes a picture and then it outputs what it has read to the console.

When I run this code as an Applet, the applet starts and does nothing. It just stays there with no errors of any kind (at least that's what Eclipse is showing me).

I read that I should allow the applet access, so I edited:

Java Code:

c:program filesjavajre8libsecurityjava.policy mh_sh_highlight_all('java');

And added this at the end:

Java Code:

grant {
permission java.security.AllPermission;
}; mh_sh_highlight_all('java');

Which should allow applets full access. However, there is no change - the applet still launches and does nothing. Why is the code not working when I run it as an applet?
