Does anyone use the .java.policy file to give applets permission

Hi,
I'm having trouble getting a codebase to work for an applet run from a jar file in some browsers: FF3.6.3, Chrome and IE8. The applet works in Older versions of Mozilla.
The applet reads and searches files in a folder and sub folders.

The applet works if I add a permission allowing all files to be read to a grant that doesn't have a codebase (ie for all codebases).
grant {
/* permission java.io.FilePermission "<<ALL FILES>>", "read"; This WORKS!!! Testing ONLY */


I have another entry in the policy file that allows a test applet to read a file. That entry allows ALL of my browsers to read the test file. I've tested by commenting out the entry, get the access denied message and then uncommenting it and having it work.
grant codeBase "file:/D:/JavaDevelopment/-" {
permission java.io.FilePermission "<<ALL FILES>>", "read"; /* For AppletReader Test */
permission java.util.PropertyPermission "*", "read, write";
};


Does anyone have examples of codebase= entries that work with current versions of browsers?
