Youre trying to access something you dont have permission to

  Caused by: java.security.AccessControlException: access denied (java.util.PropertyPermission user.dir read)

You can sign your applet

And/or set the permissions in the users home directory

Applet has limited permissions. Non-signed applet cannot access file system and part of the system properties. In your case you tried to access user.dir.

You have the following solutions.

  1. try to avoid using user.dir
  2. sign your applet
  3. do not use applet at all. Use java web start instead.
