Hello, i want to access some files from my applet in a browser. I have signed my applet:



         137 Sun Dec 11 13:01:28 GMT+01:00 2005 META-INF/MANIFEST.MF
         258 Sun Dec 11 13:01:30 GMT+01:00 2005 META-INF/BORG.SF
        1044 Sun Dec 11 13:01:30 GMT+01:00 2005 META-INF/BORG.DSA
           0 Sun Dec 11 12:53:38 GMT+01:00 2005 META-INF/
sm      3722 Sun Dec 04 11:05:34 GMT+01:00 2005 browser.class

  s = signature was verified
  m = entry is listed in manifest
  k = at least one certificate was found in keystore
  i = at least one certificate was found in identity scope

jar verified.

Warning: This jar contains entries whose signer certificate will expire within s
ix months. Re-run with the -verbose and -certs options for more details.

But every time I call it:


<APPLET code="Browser.class" 
	archive="Browser.jar">
</APPLET>

I still get an Exception:


java.security.AccessControlException: access denied (java.io.FilePermission H:\Projects\meine_HP\borgsoft\index.html read)

So what have I to do, to access files from my browser via an applet? Thanks for your help!
