java.security.AccessControlException

[Vaibhav Tomorrow]

Hi,
I am trying to perform authorization and using jaas.policy file.
Can any one suggest what is wrong with the policy file.
it is placed in the same folder where code exists.
jaas.policy file:
grant Principal UserPrincipal "TestUser" {
permission PersonnelPermission "access";
};
The Client code is :
LoginContext loginContext = new LoginContext("Userpass",new MyCallbackHandler());
loginContext.login();
Subject.doAsPrivileged(loginContext.getSubject(),new PersonnelAction(),null);
loginContext.logout();

PersonnelAction implements PrivilegedAction.
I am trying to check the access permission but getting the following error:

java.security.AccessControlException: Access denied (test.PersonnelPermission access)
at java.security.AccessController.checkPermission(AccessController.java:104)
at test.PersonnelAction.run(PersonnelAction.java:9)
at java.security.AccessController.doPrivileged(AccessController.java:215)
at javax.security.auth.Subject.doAs(Subject.java:495)
at test.Client.main(Client.java:17)

How are you specifying the policy file to be used? In won't get used just by virtue of being in the same directory as your code.
