AccessControlException received when specifying Codebase

Name: yyT116575 Date: 01/16/2001


java version "1.3.0"
Java(TM) 2 Runtime Environment, Standard Edition (build 1.3.0-C)
Java HotSpot(TM) Client VM (build 1.3.0-C, mixed mode)

I have written an applet that accesses native code on the client pc. I have
coverted the HTML file to use the Java 2 Plug-in. It is able to run and
view in the appletviewer.

It will run in the Netscape and IE with the following entry in file:
.java.policy:

grant {
      permission java.security.AllPermission;
};

If 'codebase' is specified:
grant codeBase "http://fncpc/dennisw/-" {
      permission java.security.AllPermission;
};

The applet returns the following exception:
java.security.AccessControlException: access denied (java.lang.RuntimePermission
