simple question - policy file

  1. Default simple question - policy file

    Hi,
    I have this simple scenario. I have a target class in
    D:\java\Target.class. I have a caller class in D:\java\Caller.class. I
    also have another caller class in D:\java\BadCaller.class. I want to
    give access only to Caller.class to access Target.class. For this I
    created an entry in the policy file like this:

    grant codeBase "file:d:/java/Caller.class" {
    permission java.lang.RuntimePermission "d:\java\Target", "read";
    };

    When I run the caller classes, I provide -Djava.security.manager
    variable. However, both Caller and BadCaller can access Target class.
    Am I missing anything here? Appreciate any help.
    Thanks.

    Are you doing this in an Applet or application? You can use the
    policy file only to give permission, not to block access to what would
    normally be ok, not unless you put your own security manager check in
    the potentially forbidden code.
